Geoffrey, I am using an ICOM IC2200H in my 2001 Toyota 4runner. Perhaps I am getting noise on the interface cable but who knows where the source would be on that short of a connection. I will check

Robert, I am decoding and can see stations come in on APRSDroid. I only see the strongest stations with the engine on. That is a great suggestion regarding the BT interference. I have my phone paired

Hi, What radio are you using? Car make and model? Maybe you are getting noise on the cable between the radio and the TT4 ? Can you attach a computer to the TT4 and run the MONITOR command with and

When you say "... decode rate plummets to almost nothing." , how do you know if it is decoding?I am guessing you are actually referring to no decoded packets received through Bluetooth (BT). Does your

thanks, I'll try an AM radio. The TT4 and radio are tied directly to the battery with adequate gauged wire. I'll try the separate battery idea! Noah

Grounds and power for radio, BT, TT4 to the car battery with right size wire? I have sizable wire for radio directly to car battery with BT and TT4 tapped off of it. If an older car the spark plug

Here is a status update I that little lost pad was hard to hold in place it took the hit, but its a GND pad just like the one next to it. Anyway if you wondered if it was drop in, minus the testing on

Hey Rob, thanks for feedback - ?the documentation for MTT4 and TT4 are very intertwined so the terms are as well, my attempt here was to tie them together a bit. The MTT unit uses the PP-RTG cable to

I took a quick look at your MTT4B-Modes github. I noticed that under *Ports* you reference a DB9 connector. Does the MTT4BT have a DB9 (DE9) connector for the computer interface now? I don't have an

You need to give some details on your configuration for help: As I read this, I feel the configuration looks something like GPS5 => TT4BT <=> Android <=> APRSDroid <= internal Android GPS? QUESTIONS:

anyone else run 3rd party software? I am hitting some limits with this hardware, I purchased it after suggestions here to look at it, after purchasing other stuff. and now I feel I have hardware from

Hi tony, How have configured the TT4 Ports? I have a home made Bluettooth solution, no issues so far since a couple of years now. 73 Geoffrey --

Its a good thing we compulsively save things like old 386 PC's with their keyboards and mice! ( You knew that you would need them someday!) I have had no trouble finding NIB KB's, byt mni-KB's are

I dug into a box with colicky IBM keyboards from 1980, the year St.Hellens blew up and it works! if anyone else comes across this if caps lock works you should be good to go. Thanks for the tip. you

F5 is the command for placing the TT4 into the Configuration Mode. By a strange coincidence, the words "Configuration Mode" should appear on your LCD when you push that button. The key won't bring up

Question:I didn't find any documentation, could have missed it. searched the forums here for found something on F5! but when I press F5 nothing happens, I see text so.. what is supposed to happen?

I don’t share your hardware so no experience but just trying to lend some ideas to resolution. could it be the tt4 won’t send this data to the phone? possibly only phone gps to tt4, I don’t have
