Thanks.? I was wondering, as I am resurrecting an old TT4 (2012-ish?) and TinyTrak4 Alpha Config v0.68 is what I used at the time. Are there any issues using it with the v0.72 firmware? (I flashed

There is provision for a local time stamp tht indicates it is not real-time but CPU clock time. I instead of ending with DDHHMMz it ends (I think) with HHMMSSh from the last time the CPU was started.

If the TVOLTTWK adjusts the reading by 27mV, it implies an offset (not a gain change).That was why I asked the question. Next point:As I read the TT4 firmware manual, the telemetry output is either

The APRS weather without location seems to require a time stamp. Looking at raw data on aprs.fi for w1bst; it appears that way.

Any system that does not have an active GPS should not use an APRS protocol that includes a time stamp. There should be a non-time-stamp version of every packet type. (I hope) Bob, WB4APR

Rob, you really get me going with your posts. Thank you. What we know: Vin is voltage divided: 2.2/12.2 = 0.180 Vin has diode protection dropping it ~0.2 V Vadc = 0.180*(Vin-0.2) = Vin*0.180 - 0.036

From my observation of PEET serial data; 0 is a reported value. Non- reported values are a dash "-". Values are in HEX. Fwiw

Gil, that is what I read too. Rob, the PEET data has a date (MM/dd) and time (hh:mm) in the packet it sends (data or packet modes). The TT4 is decoding like this is a leap year. It is a day behind

Some time back I corresponded with a fellow in the aprs-is (group/provider...?) system when I was formatting wx packets to be posted via the net. I recall something about the aprs-is system ignoring

Although I understand these are just "indicators", I would have guessed the resistors would be 5% or 1% (typically not a big cost hit). I always wondered how the TVOLTTWK value worked.? Is it an

You have a TEXT port and a PEET port, so no GPS port. I am curious how the MTT4BT gets a time and date with no GPS attached? As far as I can tell, there is no RTC and no means of setting the time.The

Gentlemen, Your understanding of these issues is an order of magnitude beyond my own, but being ignorant of something never caused me to stop chiming it! I just wanted to point out a few things: The

Although the TELVOLTTWK has a resolution of 0.27v / bit, so you should be able to do the math and get it close in 1 shot (1.5 / 0.27 or 4 - 5 bits.? Since you said "almost", I set TELVOLTTWK 124 and

Thank you Robert! I am just using the ^V method, however I will turn on the telemetry option as well since it will likely produce a sexy graph in APRS.fi that is something I can check from anywhere

Thank you Rob. There seems to be issues with TT4 and PEET Brothers telemetry. I do have the weather packets going out now without the position. The system seems to ok with the format once time and

Sent from e-mail but did not seem to post. Yes, the MTT4BT voltage monitor is a simple voltage divider of 10k / 2.2k. So Vread = Vin * 2.2/12.2 or 0.180 Vin.? So reverse conversion would be Vread /

I don't know much about sending weather information using the Byonics products, so can't help there. BUT ...Looking through the configuration file? you attached to the original message for anything

Good day, I've got two MTT4BT's deployed in Central BC as digi's. We're finding that the voltage they're reporting is off by more than a volt each. One, "TWOSIS" is low by about 1.5V most of the time,
