Is the root question essentially whether you can feed one Port PEET data and receive Data from your radio's audio on the other Port as KISS? It may be a trick question, but it seems to me the answer

I am not quite following this idea. The TT4 has 2 ports, so you can make 2 connections -> B. Peet Weather You appear to have something setup like this:?? Peet -> Pi (Java) -> TT4 (port B) -> Radio

Greetings from Columbus, I am currently using my TT4 to transmit Peet weather station data into the APRS network on 144.390 using port B of the "Y" adapter. That was the easy part....? Now, I would

Steve, Excellent! The MT-8000FA might be over 84 years old ( In dog years...) so it has a right to have some of its joints to get a little crepitus. Keep in mind that the Gate Voltage will also decay

Thank you Allen. I can not tell a lie. I had the meter hooked on to the PCB at the proper points and never saw the voltage change from "0", so yes I was measuring when the mt8k was not transmitting.

Steve, Just to be clear, you are reading the voltage on the gate of the amplifier during the time the device is transmitting? It is normally at zero Volts. If you don't see any voltage on the

Although I can see the aprs packets being received and translated on the Kenwood TMD710GA mounted in the same vehicle as the mt8k, I do not see any packets being posted on aprs.fi no matter how close

UPDATE for folks: Sure enough the cable was wired VERY wrong. Got that sorted out according to the pinout from Allen (Thanks again!) and set the settings in the TT4 to?ABAUD 19200 and AMODE KISS per

Alright, I got my "home brew" cables taken apart and I'm pretty sure I see the problem. This thing is NOT wired right and might have some broken connections. It looks like he built it with scraps of

"Have you gone through the CALIBRATE and MONITOR setup to get the TT4 configured for the radio you will be using?" Yes. If I connect the TT4 to the PC, TeraTerm displays all the packets the TT4

Almost all APRS clients prefer the TNC (TT4 in this case) to be in KISS mode. I run my TT4 with APRSIS32 all the time.? I set ABAUD 19200 and AMODE KISS (match in APRSIS32) Again, for

I ran into a similar problem with my home brew cable. Make sure you have pins 7 and 8 jumpered (on the DE9 connectors going to the devices, not on the TT4) as many of the interfaces will not work

Good morning, Rob! Thanks for the reply. Sadly, I did not get a schematic with the cable. This was a "I'm not doing APRS any more and so I've stuffed everything that looks even remotely related to

Thank you very much for the excellent link and the callsign comment! :D I will admit to not being the world's best web searcher, so that diagram was eluding me. It's exactly what I was looking for!

You need to figure out how the splitter was mode. Did the person you received the splitter from give you a schematic of how it is connected? There are 3 legs to the splitter: PC????? DE9F where

Vaughn, Here is a link to an old post with the cable pinout you SHOULD

Howdy folks! I have a TinyTrak4 with display and keyboard running 0.72, GPS5, and a home-brew splitter cable another ham gave me years ago. I'm trying (for the first time) to use the splitter cable

I used the diagram you speak of just to get the info on the GPS wire colors. You are right - it confused me too. So I re-soldered the GPS wires using the green wire (GPS TX) on pin 2 of the DE9F which

When I look at the website diagram, I see the explanation to be confusing.What are they telling you about the pins on which connector?? The Green TX pin from the GPS will connect to the RX pin of the

I've been using one of these on a tinytrak FA since 2015 or so. yes it has a small led along the edge. sirfstar 3 is very good. it is on the rear deck of my car with the mag antenna on the trunk lid.
