Hello Luc,

The D710's "tune" button is on the control head so when the APRS system running on VFO-A decodes a specific APRS beacon packet and you press the "tune" button, the radio can QSY VFO-B to that same frequency, PL tone.? Your I assume your Yaesu FT2600 is meant to be a dedicated APRS radio so having such an option from DIrewolf would QSY your radio away from 144.390 to this alternative frequency.? That would be bad.? It doesn't matter though as your Yaesu radio doesn't support RIG control so you cannot remotely change it's frequency anyway.? Very few VHF/UHF FM radios offer rig control but the Kenwood v71/D710s do (though they are all EOLed now).

YAAC's repeaterfinder plugin has the logic to parse APRS repeater objects and send the commands to tune a Kenwood radio as well. You need the Kenwood PG-5H cable to the transceiver body to send the tuning commands. The repeaterfinder plugin also can tune Icom radios using CI-V command protocol.

Hi Luc,

The Tune function is a feature of the TM-D710 and some other radios whereby you can have the non data-band side of the radio QSY to the frequency advertised in an APRS packet, but only IF the APRS packet is decoded by the radio's internal TNC AND the APRS packet is in the correct format here. See here

You can advertise the frequency of your repeater in direwolf by sending that format. I don't know exactly what to add to the direwolf.conf because I use YAAC to beacon my repeater.

It should look like this?

Re: problem implementing tone-keyed radio-to-soundcard interface

 

The block diagram is a bit harder to follow for me, and I found it after I looked at the PDF. The schematic in the PDF is much easier to follow.
The input audio is amplified by the first half of the op-amp, The output is rectified by the diode and the resulting DC is used to charge the capacitors (earlier e-mail) That DC is used by the second half of the op-amp (as a switch) to control the turn on/off of the leds. The one led obviously being the one in the opto. If you want to see the output from the opto you would have to connect a load, for instance an LED with a 1k resistor from B+ to the collector of the opto. I'm reasonably sure any op-amp would work for the application LM386 MC1488 etc. If you look up the application notes for op-amps there is probably a detailed explanation of the + - inputs (inverting and non-inverting) and how they relate to the output. I was originally surprised that there was not a split supply, but as the op-amp is used the way it is, it is probably not necessary to reproduce the input waveforms verbatim as they are only looking to make DC.

Rob and Sid, I think all of the op-amp circuit is not present.

I am sure you guys arrived at the same conclusions I did.
Years ago I built a similar circuit for a fast, no tail squelch. I used the op-amp to control a 4066 switch. It worked the same only if audio (un-squelched noise was present) it held the 4066 closed. If a signal (no white noise) was present, the 4066 was connected. The problem was if the circuit was overdriven with audio it would chop as it would see audio as noise, so the levels had to be set accordingly. Not a big deal and worked great FOR VOICE. I don't know how well this keying circuit would work for data as what is considered fast for audio might be way too slow for data from the point of keying and un-keying.
I personally would NOT bother with re-inventing the wheel and use a GPIO pin for the PTT. I am also not a fan of audio transformers but that is probably just me as I have never had a lot of luck with them and, for me, seem to be hard to get for some reason, although I did just strip some out of an audio control rack.
The intention of the resistor and capacitors is to hold the input for the second op-amp (PTT control) providing delay. The resistor bleeds off the charge on the capacitors (capacity adds in parallel), so the more capacitance the more the delay and the resistor bleeds off the charge to release the PTT. 73 de Gil ve7bul?

Re: problem implementing tone-keyed radio-to-soundcard interface

 

In theory, that is the purpose of the 4N25 optoisolator.? However, in practice, the sound card is not differential, so it really isn't isolated.

As for the rest, I am not sure what you are trying to do with this circuit.
Are you trying to use this as a pseudo VOX for the PTT?
?? In other words, you want the LM158 to generate the proper signal to cause the PTT to active the radio?

I am not following the circuit.
?? The 4N25 seems to have 5V on it (through diode), which is looking or ground to activate the PTT.
? Since the other end is connected to Bout, that means Bout is suppose to provide that ground when you want to send.
? So whatever the end result, the circuit needs to be inverting (when audio is in, Bout needs to be low?

So A and A- are the first amplifier stage.? But this has no feedback to provide amplification.? Is this intended to just be an inverting buffer?
The output (Aout) goes through a diode and into the second stage (B-).
? Are the diodes, caps, and resistors intended to be a peak detector?? The B stage has no feedback either, just another inverter?

Or am I looking at this wrong?

Thanks very much for the help, Rob and Gil.? It's making more sense now.? I changed the circuit to this:
(from??schematic, page 6)


I thought that the point of the 4N25 opto-isolator was to separate the PTT ground from the circuit ground, but in my radio G and MG are the same.

With measured ~110mVac at the sound card output (my phone with spotify), I get ~500mVac at PTT but the led doesn't light.? When I take the phone away it doesn't change.

I'd be grateful for ideas on how to debug this.? Also I'm not very clear on what the LM158 op-amp is is for, besides increasing the input voltage.

Re: APRS packet every 30 seconds.

 

I can help with part of this.
X-Digi is by John Hanson of TNC-X. The X-Digi was an addon board that allowed the TNC to be a stand alone DIGI.
MFJ now sells the MFJ1270 and the x-digi addon board from his design.

What is the best way to find the radio?
Good question.?
I do not think the TNC-X has a TO designation (as it is just hardware), nor do any of the 2 addon boards (as far as I know).
If you are lucky, and have some way of looking at station list (MHEARD) with comments, you can look for MFJ1270 or TNC-X in the comment.

What is the location (area) with the issue?? Maybe a look through nearby stations would give a clue.
Of course Direction Finding is always an option, but kind of tough on a busy frequency.

I can confirm this specific post/approach within this Github issue works for me where as the other posts/approaches don't work.? I think the root issue here is the multiple levels of abstraction using variables when trying to be user friendly actually makes the Bash shell script break.?

I've attached a copy of the modified script here and we'll see if groups.io posts it or not.? If it does, review it and give it a try and let us know if it works or not.
