What is the maximum current the PTT line can switch? Just ordered two kits. 73, Tim N1BTQ
It is switched with a 2N2222A transistor. If more current capability it needed, you can interface a relay.

Release date for TT2???
It is looking like beta will start in December, and release a month or two after that. Also, it looks like I may be able to use the 18 pin PIC16CE625, which would work in the existing hardware.

From: Ken Baremore (w0krb) on Tue Oct 10 08:02:25 2000
I have a Kenwood TM-V7A, a laptop computer with Street Atlas 7 and the Earthmate GPS receiver. I need to know what is needed besides the tinytrak to have an operational aprs system. I heard of some adapter that will change the rockwell data from the earthmate to usuable data for the tiny trak. What is it? Where can I find it? What else is needed to hook up to the laptop and my radio? Can I use one band of the radio for APRS and still use the other side for normal communications? Will this hook to the data port on the V7A?
The GST-1 will allow use of the Earthmate with APRS. To build a tracker, you need a TinyTrak, or a TNC, your radio, and a NMEA GPS, or an Earthmate and GST-1. To monitor APRS, you need your laptop, and an Internet connection, or laptop, a radio and a TNC.

My first TT works great, and am about to order two more units. Then i see a tt Mk 2 is in progress. Do i wait?? Any information about price, features, etc??
It will probably be a couple months away. Features should include all the TinyTrak features, plus altitude reporting, smart beaconing, time slotting, 9600 baud, WX support, and more.

If anyone is interested in looking at the TinyTrak inside a Delorme TripMate, go to http://kliernetwork.net/aprs/tinytrak - Just made up a quick page for people to look at. Once again, the TinyTrak is a great product!

From: Charlie (KB8PXM) on Sun Oct 8 11:53:22 2000
Help with using a Delorm Tripmate with the TinyTrack.. I have modified the tripmate to initialize on power up, works on the computer. The Tinytrack works with my Garman gps. Switched pins 2 and 3 from the gps. Any Ideas on what to do next? Thanks!
Try to confirm that the serial data is getting into PIC pin 3. Use a scope or a logic probe. Also, try sending GPS data from a computer terminal program to the TinyTrak.

From: Roger Sewing ((ZL/)N6TNF) on Sat Oct 7 03:05:02 2000
Greetings: I am currently living in Gisborne, New Zealand, and am trying to promote interest in APRS here. I would like to order a Tiny Trak but need to know the shipping costs/methods and payment arrangments (other than putting the credit card over the net). One ham here had a Tiny Trak brought back from Europe (with Dutch instructions). The unit works great but is having difficulty programming the parameters. (the ham who brought it back has HIS callsign on it) What parameters can you change? I suppose my unit should have all the info included. Also, do you program the "chips" and sell them alone (without the kit itself)- it is possible this ham's "chip" may be no longer any good due to some drastic programming measures. Hope to hear from you soon. Thanks for your time. 73!! Roger Sewing, ZL/N6TNF
You can use CCNow for on-line ordering. If you do not wish to use a credit card, a check in $US can be sent to my address on the ordering page. With the config software, you can adjust callsign, digi path, transmit rate, txd time, quiet time, calibration, beacon text and rate, and some mic-e settings. If the chip is damaged, replacement chips can be ordered by contacting me.

STEPHEN: We having seem problem. We mention this several times to Byon.

From: Hans () on Fri Oct 6 03:59:00 2000
TINY-TRAK NOT TRANSMITTED HEIGHT! we found out TT is not transmitting height information in his beacon. Das anyone know why not? We use the BETA 1.2 VERSION. And also report Byon several just after BETA release, about this problem.
TinyTrak does NOT send altitude data. Version 1.2 decodes the position information from the GGA sentence only. TinyTrak II is in development, and will send height.

From: Werner (oe9fwv) on Fri Oct 6 01:09:27 2000
Does the Tiny Trak transmit height? I have a Garmin III+ and Tinytrak Firmware version 1.0 Any comment welcome... 73! Werner
No, it does not.

From: Gerald Peklar (DK7XE / OE6DLD) on Wed Oct 4 09:27:04 2000
both TT's i received and built up are working fine! but now i need help: i want to supply power to my delorme-tripmate via the 9pin connector of the TT. does anyone have information about ?? which pin do i have to use for +5V?? - another thing: some guy's had problems with setting the transmitting audio-level. i replaced the 10k pot with an 5k fine tuning one and add an 5k6 serial. now setting the level works!

From: Stephen H. Smith (WA8LMF/6) on Mon Oct 2 15:35:34 2000
Just finished assembling the kit I received about 3 weeks ago. The automatic beacon mode works perfectly but I CAN NOT get the PTT-triggered Mic-E mode to work at all. I saw the diagram below on this BBS (that was missing from the documentation) showing the added diode so that mic PTT can key both the radio and the input to the TT. What is the reference to setting S1 to the alternate mode about. Is there some beacon interval value that says don't beacon on a timed basis at all but respond to PTT instead?? All I seem to get is automatic beacon at either the "normal" rate or the "alternate" rate depending on the switch... Is there some other setting I need to make??
SW1 should be left unconnected (floating) for MIC-E mode. Set the primary time to 600 seconds, and the secondary time to 10 seconds. If PTT IN pin is grounded when the mic is keyed, then, when it is released, if it has been at least 10 seconds since the last beacon, a burst will be sent. When you stop sending voice, a position will be sent every 10 minutes. I've had this working. If anyone else has also, please let me know.

From: Mike Killian (kc7jgc) on Thu Sep 28 20:04:42 2000
I am looking to get into tracking. I have 2 meter equipment (Yaesu ft11 and ft2500 and Icom 2000). I have not TNC's yet, but discovered the www.aprs.net web site. Oh, I also have a Garmin GPS II. Will your unit interface to these?
Yes, TinyTrak should work with your equipment.

From: Mike Huffstetler From Kit Builders in Watsonville. Ca (wa6ouw) on Wed Sep 27 14:05:16 2000
Was talking to Doug Mckinney at Mckinney Technology and he said you might be interested in having your kits assembled. I build through hole as well as surface mount (0805/1206)with references from Doug , Dave Benson/Small Wonder Labs, etc. Pls advise. 73's Mike/Kit Builders

I WONT TO PLUG MY GPS RANDMCNALLY ON MY TINYTRACK HELP ME
I'd recommend cutting off the DB9 and PS/2 connector, connect the red wire to 5V, the shield to ground, and the white wire through a 10K resistor to DB9 pin 3. Do not use the yellow wire.

From: SIMARD NORMAND (VE2LHS AND DIGI VE2LHS-3) on Sat Sep 23 18:33:39 2000
sorry for my english. I SEARCH THE PIN OUT FOR MY RANDMCNALLY GPS FOR CONNECT WITH MY TINYTRAK. WELCOME FROM qUEBEC 73 VE2LHS SINCE 78

GUY: I notice the same. Not possible to set exactly on freq....but still works oke here.

From: Mike (KB0TIY) on Sat Sep 23 10:53:32 2000
Thanks for the reference to Digi-Key there in MN. Found all the parts I need and look forward to operating the device for tracking. 73's

From: Ted McArthur (AC7II) on Thu Sep 21 19:29:30 2000
I built the TT a few months ago and it has been working fine but in a hurry to get it set up in another vehicle for a bike race it got reverse power (not good) the 7805 went bad i think the pic smoked too. So I had a pic-e from tapr and I down loaded the hex prog sent in your download file and it looked like it programed. but after replacing the regulator and pic I don't get the flashing lights only power and when trying to verify with your config prog it says it isn't connected. do you think it didn't prog right or did something else also go.
If you don't get the flashing LEDs, it is not programmed correctly. Make sure the PIC is receiving power at pin 14.

From: Ken Bording (W5KNB) on Tue Sep 19 17:17:15 2000
What is the max distance the LEDs can be remoted from the PC board? Also, can any of the Radio Shack LEDs (designed for panel mounting) be substitued? I'd like to have the LEDs visble from outside my tracker cases. Thanks in advance. Ken
They are just standard LEDs, so any ones will work. You can probably remote them a couple feet away.

From: M. Baratta (K3NMR) on Mon Sep 18 06:28:50 2000
Is the Tiny Trak compatible with Trimble's "Acutime" (GPS receiver/antenna) that outputs TSIP (Trimbles protocol) using Rockwell's binary format?
No, only with GPSs that will output the standard NMEA-0183 format ($GPRMC)

From: Earl S. Garber (N3EG) on Sun Sep 17 17:07:33 2000
I got to see a TinyTrak recently - it was small, but I'd still like to see something smaller...I have a Tripmate and already have a 5 watt radio which would fit inside with a smaller unit...any plans yet for a SMD version? I'm up to the challenge of assembling it.
I've been thinking about it, but made no progress yet.

From: Guy Beaumont (G7BWP) on Sun Sep 17 07:04:40 2000
Having tried both 1.1 and 1.2 betas, I have found 1.1 is more accurate with regard to tx tones. Using a measured 10.000080 mhz clock for the pic, cal value of 61 output tones are 1197 and 2204 hz. The 1.2 beta gives 1202 and 2254 hz. Otherwise it works superbly. The individual tone selection allows easy setting up of the unit.
The 1.2 version may not have more accurate tones, but should decode on TNCs better, especially Kantronics in Software CD mode.

From: John Scott (N0HZN) on Sat Sep 16 19:34:30 2000
For those of you that have been trying find a way to combine a TT with a GPS to make a low cost tracker, I have a possible solution. I mounted the TT inside a Delorme Tripmate GPS. The total cost was about $85 to $90. Add a radio and you're all set to go. I've created a web page to go take a look at what I have done with pictures and short desrciption. http://members.aol.com/n0hzn Go take a look.

From: Mark Stappenbeck (N0PWZ) on Sat Sep 16 16:12:38 2000
I've received the tinytrak and I've yet to build it (unfortunately). The troubleshooting section of the construction manual states that, "the only NMEA-0183 GPS string recognized by TinyTrak is $GPRMC". I currently have a Trimble Flightmate GPS that outputs a number of different formats including what is referred to as "RMC" format. I suspect that this is the same format, but I don't know for sure. Does anyone have the specific format of this sentence that the Tinytrak accepts?
Yes, I believe that GPS will work with TinyTrak. TinyTrak expects sentences like : $GPRMC,201050,A,3610.9912,N,11516.4034,W,0.0,005.2,240799,013.7,E*67

From: Bill Engelke (AB4EJ) on Sat Sep 16 12:59:38 2000
At what baud rate does tinytrak send packets? 300, 1200 or 9600? I have tried various settings on my TNC and have not yet gotten successful decode. I can try changing the calibration setting, but want to make sure I have the right baud rate first.
TinyTrak sends 1200 baud packet.

From: Doug Leach (VE3XK) on Sat Sep 16 11:14:54 2000
Hi Byon Kit arrived last week. I saw the plastic bag of parts and the manual so threw out the envelope. I was just getting ready to assemble the kit when I discovered there is no PCB in the plastic bag. If it was supposed to be in there it was not. If it was separate in the outer bag I must not have noticed it. The garbage was picked up Thursday so it is long gone. Can I previal on you to send me another board by mail to Doug Leach - VE3XK, 683 Richmond Rd., Ottawa, ON K2A 0G6 CANADA. It can just go in a mail envelope. No cover letter, invoice etc required. Let me know by e-mail what I owe you. Vy 73 Doug VE3XK
No Problem.

From: Karl Geng (N1DL) on Sat Sep 16 05:56:56 2000
Byon: the replacement PIC did the trick - all is back to normal. Have used TT now in car, yacht and last week on my plane. Any chance for altitude mode in the future? 73 Karl PS WX permitting I'll fly up to Orlando
TinyTrak II will support altitude.

From: shamim khan () on Wed Sep 13 16:42:11 2000
what is the smallest size of the tracker, i have heard that they build a tracker that can even track a small fly so how small that would be,can u give me more information on that. thannks.

From: Victor Luis Quintili () on Wed Sep 13 05:24:08 2000
I need information of GPS equipment to produce in my countries.(Argentina)

From: Jim Hopper (K5IWK) on Tue Sep 12 17:19:17 2000
If I change R5 so I can use it with a mobile rig, can I still turn the deviation down enough to switch back to a hand-held? I tried it on an Azden PCS-3000 but not loug enough. Am using it on a Kenwood TH25AT now.
Yes, changing the resistor to a lower value will give more adjustment range, but you will still be able to set to the original range.

From: Joe LaGreek (N0OTM) on Tue Sep 12 14:08:02 2000
Used 3 TT for our MS-150 last weekend. All worked perfectly. Thanks Joe

From: Scott Currie (KJ7QY) on Tue Sep 12 10:48:57 2000
Saw the TT at the NWAPRS Summer Gathering. Mine is on order! Any chance TT will support weather data sometime soon? Sure be nice to have a TT sending the home station and weather data and let me use the TNC for other stuff. Regards, Scott
Yes, TinyTrak II will support weather stations. I am looking for current WX users to beta test. Please contact me if interested.

From: Greg Lane (k7sdw) on Sun Sep 10 08:41:56 2000
Got the tiny trak assembled. I take it you can not access the tiny track without the radio attached? When I power mine up all I get is the pwr led lit and everything else blank. The program will not talk via my com port. Is there an error on the board for a trace or pad ? I checked against the blank board (bought 3 kits) and recheck the components and alignments of parts. Made measurements at the voltage reg, 4.98. and hope to see what serial data will show up on a scope. The varb resistors were a bit tough to get through the holes to make a good solder connection. Any ideas would be appreciated. Greg
If you are not getting the LEDs flashing, then there is a problem with the chip or the traces/soldering on the PCB. Check the soldering for cold joints and bridges. Try jumpering 5V to the PIC socket for the LED to see if it lights. If you think the chip is bad, I will replace it.

From: Bob Hollister (N7INK) on Wed Sep 6 14:18:53 2000
Great package. I used it last weekend and seems to be working well with IC281H 2 mtr & Garmin 48XL GPS. Toshiba laptop used for setup, no problem. Is it supposed to report elevation? Using the same GPS unit(Garmin XL48) with the KPC-3+, Elevation was also reported. Tiny Trak does not seem to provide that data. I use WIN APRS 2.4.3 for monitoring. Has anyone used TT with Yaesu/Vertex 150 HT?
Altitude is not sent. Watch for TinyTrak II to add the feature.

From: Bill (N5ZTW) on Wed Sep 6 04:43:54 2000
Beta testing of V1.1 firmware and config looks good! GPGGA now supported & working! Tone generation great for tweaking with O-scope. Super improvements.

From: Hans () on Mon Sep 4 12:25:52 2000
BYON: We will upload a small/simple diagram for PIC programmer on homepage soon. Needed 2xR 1xC 1xD this will do the trick.

From: Jim Fonte (K9FI) on Mon Sep 4 05:43:15 2000
The TinyTrak is really a FB(!) product!! I built and installed the TT inside a self-start-modified DeLorme TripMate (removed the battery case, and used that location). The green GPS-acqusition LED & the red TX led is mounted on the TM-case, along with a bullet-type DC jack, three 3.5mm, 3-conductor closed-circuit jacks (one for TX-out, one for GPS-data out, and one for TT! programming. The TT!/TM combo-package serves an ICOM IC-2AT + RS 30W amp (packaged in a small, plastic case. Byon...you and your associates did a wonderful job developing a very useful tool for amateur radio --- I appreciate the quality of your collective crafting! I look forward to your next projects!! VERY 73! Jim, K9FI

From: Markus Fackler (DL1GFM) on Sun Sep 3 01:58:32 2000
Hello Byon, The new firmware works fine with the $GPGGA data form my GPS. Thanks for the good work. markus

From: Chris Verbil (N5CV) on Fri Sep 1 14:33:14 2000
Byon, my kit went together quickly but I am having difficulty talking to the PIC through the DB9 comm port. When powered up, the TinyTrak does the expected LED light dance and the PTT LED illiminates every two minutes as if it is sending (I don't have the radio hooked up yet, though). So it would appear to me that the microprocessor is alive and functioning normally. When I use the TinyTrak configuration utility, it does not find the board. I have tried multiple PC's, swapped cables, comm ports, etc. but no luck. I even checked with a null modem in line but your documentation seems to tell me that is not required. When I put a protocol analyzer on the port there is no traffic coming out pin 2 of the comm port. I have checked the board traces extensively and find everything is as it should be. Any ideas?
Do you see data entering the PIC at pin 3 when you attept to find it with the software? If you hook up a GPS, does it read it, turn on the GPS LED and send the position?

From: Vince Staffo (WB2FYZ) on Wed Aug 30 12:47:30 2000
Byon, Has anything further been done to enhance the firmware in Tiny Trak to operate as a stand alone fixed position tracker without a GPS unit attached? I have a 16F84 programmer and I would be willing to test firmware for this when I get my Tiny Trak up and running.
TinyTrak II should have enough room to hold a stationary position beacon.

From: Michael Pischel (KB0TIY) on Mon Aug 28 18:30:04 2000
I bought a Tiny Trak and now need to buy a connector for the header? Where is everyone buying these? I tried Newark's and found I bought the wrong type... Any help is great! Mike KB0TIY

From: Ted McArthur (AC7II) on Sun Aug 27 20:06:30 2000
I have been using TT for about2 months now its been working great. I prevously had put together a PIC-E had all sorts of bad luck with it. I took the TT to a APRS conference this week evcerone feel in love with it. Any plans in the future to make one that you can have a computer output for running like winaprs with.
The TinyTrak hardware cannot decode packet, so probably not.

From: John (N6NHJ) on Sun Aug 27 18:31:55 2000
Oh yea, what other adjustments can I make to make it more accurate for receiving TNC's?
Try different calibration values to find which ones decode best on TNCs

From: John (N6NHJ) on Sun Aug 27 18:29:41 2000
Byon, I received my tiny trak last month or so. Great little unit! I have been using it all the time. I have noticed that the packet does not get captured about 50-60 percent of the time while I travel. I just checked the deviation with an IFR, and cannot get it to go below 4 khz, but the signal looks clean. If I turn the pot any further, it just goes to zero. It seems that the pot keeps it at 5 khz most of the range, until just before the limit at one end, where it goes to 4 khz, then drops off to zero. Also, my red power on LED has never worked. What can I do to get the deviation to 3 khz? I am using it with a Radio Shack HTX 202 radio.
If you change R5, you should be able to get more or less range from the pot. Doubling R5 will give half the range on the pot (finer control), Halving R5 will give double the range (but less control.)

From: Byon Garrabrant (N6BG) on Sun Aug 27 16:20:41 2000
I have a beta version of the next TinyTrak firmware ready for testing. This version allows generating test packet tones for calibration and deviation setting. Also included is support for $GPGGA sentences. eMail me if you have a PIC programmer and would like to test this version. Thank you.

From: Byon Garrabrant (N6BG) on Sun Aug 27 16:18:25 2000
Due to CCSLIDE no longer accepting international orders, I have switched to CCNow for accepting credit cards. I will still accept PayPal and checks.

From: Vince Fero (AA7JB) on Sun Aug 27 11:16:24 2000
Corrected the problem I had with my icon not showing on my maps. Byon got me going in no time. I was running WinAprs 2.46 and apparently there is a glitch in that version that drops the 1st number in the longitude (my icon was in Morocco). I loaded WinAprs 2.45 and it tracks Tinytrack fine.

From: Lloyd Mitchell (KD4HTW) on Sat Aug 26 16:50:46 2000
Will the TinyTrak work with a unsquelched radio or in DCD configuration? This unit along with a MFJ 8621 would be great! email answers direct.
No, but if APRS activity is low in your area, you may be alright just leaving the audio input unconnected.

From: Vince Fero (AA7JB) on Thu Aug 24 17:12:14 2000
Got the Tinytrack last week and it was a breeze to put together. Mounted it in an Altoids mint box with the DB9 out the side. I have one problem, it does not show an icon on the map for my station. I tried different symbols. I am running Winaprs and the tinytrack is in the heard list with the correct location but nothing on the maps. I have no problem seeing other stations. ..Vince..
It seems this may be a bug in WinAPRS 2.46

From: Karl Geng (N1DL) on Thu Aug 24 12:16:02 2000
I put the Tinytrak together and it worked right away but when I handled it a few times it gave up its ghost. I believe I killed the microprocessor. Can you send another one and charge my credit card again or bill be and I send a check. Tks Karl N1DL Karl Geng, 695 Embassy Ct, Marco Island, FL 34145 Fax 941-430-2063 Tel 430-2015

From: Mike Pendley (K5ATM) on Wed Aug 23 20:16:49 2000
I hate to keep putting Byon on the spot via this list (he is really a nice guy) but here goes anyway. Does anyone else have problems with data being transmitted when the valid lamp is off? When I first start up my system my Tripmate is often not locked in before the first packet is sent. As a result my first APRS data point is far away from where I really am. The Tripmate is usually locked in by the next cycle and I appear to race at warp speed to the correct location. I am thinking about ANDing PTT and Valid with a simple diode AND gate but don't want to bother if this is a local APRS support issue. You can see my TT/Tripmate combo (I installed the TT inside the Tripmate) at http://www.rt66.com/~mycall/TTT.jpg -Mike
I'll add the ability to holdoff transmissions during invalid data to the wish list.

From: Mike Pendley (K5ATM) on Wed Aug 23 19:59:06 2000
Regarding calibration. Byon -- I was wondering if you would be willing to post a simple program for the TT. All it would do is assert PTT and output a continuous mark (or space). A simple frequency counter (like the one in my Fluke multi-meter) could then be used to fine-tune the calibration value (with no radio connected). Deviation would be easier to measure with a continuous signal to work with as well. I bet you could just take your current software and put the "output a mark subroutine" in an infinite loop. -Mike
The next version of the TinyTrak firmware will have this feature. Beta testing begins soon.

From: Mike Pendley (K5ATM) on Wed Aug 23 19:47:30 2000
Regarding my position problem (see below). Byon was very quick to respond. We exchanged e-mail all weekend trying to understand and resolve my problem (Thanks Byon!). Not sure I understand all the issues. All I know is if I leave the PATH pick list as "conventional" and put wide3-3 in the path at the top -- every thing seems to work just fine. -Mike

From: Brian Klier (N0QVC) on Tue Aug 15 19:49:42 2000
First of all, I'd like to say what a simply amazing little device. I placed my order on Saturday, and received a little package on Tuesday!!! The Assembly Instructions were very straightforward and easy to follow. It's a fun project for an evening... I am posting a message today primarily to ask a question. The 78L05 that came with my kit is non functional. The TinyTrak works fine hooked directly to +5 using the connections provided. If I try using +12 through the regulator, I get +12 at the Input of the reg., and 0 Volts at the output. How can I go upon getting a replacement for the 78L05?
I would be happy to send a replacement 78L05, or, if you can't wait, you can pick up a 7805 from Radio Shack.

From: Curt (WE7U) on Tue Aug 15 09:30:01 2000
A pic huh? Prepare to be scared at what I've done: http://wetnet.wa.com/~we7u Click on the "ruggedized" link and picture links are at the bottom. Site is down right now so I'll tell you: 2" I.D. ABS plastic tube, 20" long. Contains batteries, tinytrak, Trimble SveeSix GPS. Added a 3" I.D. extension temporarily to house ICOM IC-2AT HT. Will remove it when I find 2-meter transmitter board that'll fit the 2" tube. Ruggedized packaging for search & rescue. Fun stuff.

From: Espen (LC3ZBT) on Tue Aug 15 04:02:16 2000
Suggestion: would it be possible for the byonics site to house a few pictures from users of TT, to show other people mods and others tecnical solutions. Wold bee great to see how others are "doing it". My TT works great, the sad thing is that i am the ONLY in my town to do APRS and not a digi in sight
I'd be happy to. Send me any pictures or URLs you have.

From: Hans () on Mon Aug 14 15:22:28 2000
McCOY: Cali set around 60 will do the trick using normal xtal, and connect a GPS to it who having view at 3 sats, otherwise nothing is happening in TT.

From: McCoy (N5YAV) on Mon Aug 14 10:44:55 2000
Thanks Curt,,,I'm in the process of trying all of your suggestions till something works. I'm hoding my breath each time I plug or unplug TT to/from computer that TT doesn't break. Guess I should run to town to buy a cable. I have added a second DB9M with pins 2 and 3 crossed on a short cable to make the Garmin III hook up a bit easier. Not to bother, I don't intend to hookup computer and GPS at same time. I'll keep the group informed of developments.

McCoy: On three different TinyTraks I had to adjust the calibration value to three different values. See my other messages below for details on a spectrum analyzer program for DOS that works with soundcards. You can use it to walk your tones in to where they should be. Also crank your transmit delay way up until you get packets decoding, then start cranking it down. In my experience the audio should sound QUIETER than most of the rigs on the air when you have the audio level set properly. Most people are overdeviating. A LOT!

To Byon or anyone who can help. I got the Tiny Trak together and it's working, but not putting out packets that my TNC will decode. I have tried adjusting the audio out pot to many different positions, but it made no difference. I'm using AEA PK232 TNC and winAPRS. I can copy many stations with this setup, but it doesn't hear the Tiny Trak. When I monitor the receive audio from Tiny Trak, it sounds OK. I'm thinking of maybe adjusting the keyup delay or the resonator calibration or both. All suggestions for help is welcome. Thanks--McCoy
It sounds like you should try adjusting your calibration setting.
