Hello, greetings to everyone in the group, if anyone knows how to configure the Tinytrak3 plus for digipeater I can't do it, any help I would appreciate it .... 73 '

I have used several.? The TT4 uses the LM335z in a TO92 package, I think.? Nice because tou can connect it remotely with 2 wires. It also has the ability to add a POT for calibration.? Best done at

Thanks to all who replied. I have a lot of research to do.? Rob, any suggestions re: external temperature sensors? Steve. W7SMC

The Micro-Trak products based on the TT3 also have built in temperature sensors. Most use the LM335Z, which can be removed and remotely placed, or through an auxiliary input. The RTG-FA is pretty

Both versions of the TT4 (built & kit) have a temperature sensor on the board.? However, these are likely inside the case and not a good indication of ambient. I'd suggest an external sensor

I believe the TinyTrak 4 (non-kit) has a temperature sensor on the board and could be used to transmit the temperature via APRS. Arnie, N1BAC (-9 when mobile) Sent: Monday, March 22, 2021 4:04 PM To:

Scott, Outstanding! Since the DTMF remote has seven logic level outputs, you should be able to do a lot of things.? Thanks,? Allen AF6OF

No you understood the question perfectly, My thought for being able to reset the radio was like you said used a 30-second time delay when commanded.? Then?just reset the tnc every now and again. The

Scott, That is a lot to unpack! I think you could get away with doing what you suggest, but it is very possible you will have distortion issues from wildly unpredictable?audio impedance mismatches,

I have a DTMF controller that replies to your commands to let you know if it did what you wanted it to do.... It has a ptt output and audio in and out. Would it be okay to splice the audio out for

I'm looking for a way to monitor the temperature inside my travel trailer that I could track via APRS on my HT.? Any ideas or has someone already figured the best way to do this?? I want to monitor

Hi I'm looking to set up a tt4 on a tower as a wide area digipeater. Does anyone have a list of recommended settings? Thanks

Hmmm, I just opened it from that very link. You can probably Google "Sams Technical Publishing" to find a link your browser will like better. Allen [email protected]> wrote:

I remember those manuals with odd foldout schematic drawings.??I don't recall them called Photofacts though. I looked at the Heathkit stuff and some other old brand radios but didn't remember

One of the things I find extremely helpful is the Byonics archive: Lots of good old reference materials, old config software, etc. A nice Museum of all things

Rob, Yes, I do too. The MTT4BT is on the verge of being just a tad too complicated to draw out that way on a single page. Remember the old "Sam's Photofacts" publications filled with schematics that
