Hello, I have a Kenwood TM-V71 and I would like to transmit wx information over the APRS network via RF, from a Davis Vantage Pro2 that is a year old. I would like to use a Tinytrak3Plus. I have the data logger, both USB and serial. Can someone tell me how they do it? I also have a Kenwood DM-710 that I could use instead on the V71. I have a a Tiny Trak3Plus with the TinyPack v0.1 loaded in the TinyTrak3Plus and I also have a regular Tinytrak3plus for APRS use. I did see something about a WXTrax on a TinyTrak4Plus. I tried for information on another chat box. I did get a lot of information on how to use a do it using a Rasberry Pi and other stuff. I scrolled through some prior posts but may have missed what I was looking for. Thanks in advance for any information, Bruce WA1YZN

Hi All, Following topic drifted to a discussion about audio levels /g/TinyTrak/topic/95670230#1649 In order to not highjack the topic any longer I start a new one. The topic above triggered me to finish an article I started a while ago about receive audio levels on the Tinytrak 4. https://www.f4fxl.org/setting-optimal-receive-level-for-the-tinytrak-4/ It would be nice to have feedback from other users. 73 Geoffrey -- ___________________________________________________________ Geoffrey F4FXL / KC3FRA My Tinytrak Stuff => http://f4fxl.org/tag/tinytrak

Hi Everyone...I have TT4 with the BT...when connecting to my Android phone and running APRSDROID...Smart Beaon on (won't tx)...I have to manually enter gps coordinates for app to tx...I have GPS5 connected and it works just find when running cable from phone to radio...but not when using BT...seems to me it's the Android app and nothing to do with TT4BT...the TT4BT connects and works fine when connected to laptop using BT connection...I could use your thoughts on this...

I noticed that the two units I got shipped with “test xx” as ID and when powered it will make transmissions with these fake setup accounts thus making an emission illegally I didn’t intend. a feature request to disable tx via jumper or software so when new unit shipped it’s not transmitting with no ID You can see examples like looking up TEST22 or any other number on aprs.fi. kelly

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? Tested on TT4 and MTT4 and same results one item of note the text rolls off 20 character display on MTT4B due to a longer product name. kelly

Here is a link to a project similar to what you are doing. I got it to work on my TT4. It fits in the TT4 case. \\John KB7JJG https://www.f4fxl.org/putting-a-3-3v-hc-05-module-in-the-tinytrak-4/

I found my TT4BT module and there are two LEDs, one labelled "ACT" (Active?) and one labelled "LNK" (Link?). One's yellow the other is green. I suppose "LNK" means "Paired AND Connected" and "ACT" means "Data being sent/received," but there appears that there's no actual "Power On" LED. I'd use a DMM on the tiny 3-terminal regulator IC (Pos to pin 2, Neg to pin 1). Look for about 3.3 Vdc. Harbor Freight used to give away free DMMs as promos...do they still do that? Seems to me there was a jumper on the TT4 to control power to pin 4 of the DE-9M connector. If you determine the BT module is NOT getting power, you might check that jumper. Download the TT4 schematic to see how that works. I also found the schematic. The heavy lifting in this circuit is done by a pretty complex daughter board and it's a standard, well-known BT module that goes by the part number/name of "HC-05 Bluetooth Master/Slave Module" and I was once able to find a datasheet for the HC-05 module, but so far I don't know where THAT might be. This HC-05 module sets virtually all of the characteristics of the Byonics TT4BT adapter, so that's where I'd go to get the details of Byon's product. My TT4BT schematic MAY already be in the "files" section of the forum, if the original Yahoo forum's files were transferred to groups.io in the change-over. It may be in a folder with my name or callsign on it. I seem to remember someone complained about the way I'd named some signals on this drawing in a section relating to EIA-232C signals (I named them according to the EIA/RS specs, they ARE a little weird!...I cut back on contributing after that). So it must have been there at one time. It'd probably be named something like "TT4 Adapters & Cables with TT4BT.sch" or "TT4 Adapters & Cables with TT4BT.pdf". If the former, you might need to go to ExpressPCB.com and download their free copy of TxpressPCB Schematic Capture if the forums file is a .sch file. The TT4BT BT module is on sheet 3 (check the tabs at the bottom of the app); you can ignore the rest. I made several of the symbols for components used in this drawing, but I think component definitions are also embedded in the PCB design file they're used in, so there shouldn't be any "holes" in the drawing. So, in the future, don't just look in posts history, look in the files section as well. I was active in this forum when it was on Yahoo, but not so much now, so I'm pretty unfamiliar how groups.io works. I was a beta tester for the TT4, back in the day... Barry N4MSJ

Howdy; I decided to replace my base radio (HT) with a mobile. Went fine except the radio would just xmit all the time. Read the docs and sway I needed to remove a jumper. Opened the case, moved the jumper, powered it back up and noticed that the WX from the Peet Bros station was not working. I checked and rechecked for broken wires wince I had did a split cable arrangement between the radio and WX. Found nothing. Connected the WX directly to the computer using their cables. WX is putting out data. Hmm... So I thought I had possibly staticed it. So I have another one I use for a tracker. Reprogrammed it and installed it. Same thing, No WX, just all the letters. So now what. Suggestions? This system has worked for many years, I just wanted to change out from the HT to a bigger radio. Just don't understand what happened. Thanks in Advance 73 Mike - N7ZEF

I have another question to support@ that I figured I might ask here as well. sorry for the emails I can’t seem to find the documents to confirm my questions yet. What is the proper way the MTT4BT is supposed to connect? I have a ttusb and ttusb25 cables. How do you connect to the MTT4BT do you apply 12v (or9) do you use the db9, do you only use the 2.55? i ask because the documents say use 2,5 for pc connections but when I plug the 2.5 in nothing but a com port is present and I can’t get any data out of it but if I use the db9 port things work. I don’t know if mine was not programmed or defective? I need to do something else? it showed up called testing44 or something like that. Port a is 19200 and b is 4800 this is contrary to the documents? Thanks in advance and sorry for my name on your screen once more :) kelly

My installation in the car keeps breaking the GUA adapter, because it is not long enough to take pressure off the connectors. A Prolific cable did not work at all and I have a flexible 2 foot long FTDI adapter. However, it will not bring in the correct data stream on Putty that I am used to seeing. Byron says I need a male to male adapter to open Pin 4. I may be misunderstanding this, too. I get lighted LED's on the adaptor and each one is labeled. Can anyone tell me how to read the signal coming in? Spike N4EBF
