Hi, I have seen in svn revision 565 of app_rpt.c the new "support for Kenwood TM-D700A as a remote". Do we need a special interface (like the TM-G707 needs) or can we simply use a serial cable? Does the dedicated DATA connector in 9600bps Packet Radio mode fit our needs for "flat" audio? Where can I find the informations which has been required to implement this feature? I have another radio from Kenwood (TM-V7) and a selfmade programming cable for the memory store. Could this be another transceiver for a remote controlable station?

Yes the D700A just needs a serial cable (although it needs to be female-female straight thru, cause they used the wrong sex connector on the Kenwood radio). Yep 9600 baud packet mode is perfict. You will need to feed the URI output through the 2X amplifier since the Kenwood takes boat-loads of audio to modulate it properly. Set carrier detect and rxctcss to dsp and txmixa to voice. The radio makes its own CTCSS on transmit. I believe the V7 is the same as the TMG707 so it needs the magic circuitry. ----------------------------------------

Hello Jim,
Yep 9600 baud packet mode is perfict. You will need to feed the URI output through the 2X amplifier since the Kenwood takes boat-loads of audio to modulate it properly.
I checked the TM-D700 manual: "Output of detected 9600 bps data (500 mVP-P, 10 kOhm) -> Also functions as a common pin for 1200 bps and 9600 bps data output." RX seems the same as for 9600 baud packet mode. For TX i tried 1200 bps with a low setting of "txvoice" (radio tune txvoice 100). Seems to be another way without using the amplifier + txboost=1. Or am I wrong?
Set carrier detect and rxctcss to dsp and txmixa to voice. The radio makes its own CTCSS on transmit.
Yep, it works fine with iaxRpt for Windows. How can I change the inital frequency 146.580 MHz to another one? It is not a frequency for hamradio in germany. I found 146.580 MHz in app_rpt.c, but I hope there is another way to change it ;) Thanks! 73, Jann
Well, sorry but *WRONG!!!*. 1200 packet mode rolls off the low side of the audio spectrum and makes CTCSS decoding completely impossible. Its not too happy with the high side of the spectrum and the squelch detection either. Thats why I was forced to use 9600 and having to give it a signal higher then the Alps. I dont know why the radio is so hard-of-hearing at 9600 baud, but thats Kenwood for you. You will also need the "txboost=y" in the usbradio.conf (and the latest version of software that supports it).

This should be normal behaviour, as 1k2 packet is AFSK/FFSK and relies on normal audio path, with pre/deemphasis and 300-3000 Hz AF filtering for best performance. Ralph.

well yes, the 1200bps output pin does exactly that, but the 9600 baud pin in 1200 mode is somewhere bizarrely in between. ----------------------------------------

In fact it should transmit a clean 1k2 signal, but with wrong (flat) frequency response, so decoding it with the normal ham receivers will not be 100% OK... Ralph.

Hi Jim,
Well, sorry but *WRONG!!!*. 1200 packet mode rolls off the low side of the audio spectrum and makes CTCSS decoding completely impossible. Its not too happy with the high side of the spectrum and the squelch detection either. Thats why I was forced to use 9600 and having to give it a signal higher then the Alps.
For remote operation it already worked in 9600-mode (without the amplifier, but with txboost=1) using the iaxRpt-client with a high mic-in level (+mic boost). However using this client audio level with a standard repeaeter is much too loud... So I will try 9k6+amp next weekend. I have another question about the default shift on 70cm. I set it to -7.6Mhz for german repeaters on the radio. After I logged in with the iaxRpt-client asterisk will change it back to 5MHz for 70cm (and will jump to 2m 146.580...). I didn't found any documentation about the memory stanza in rpt.conf. Using "-" or "+" will use the default shift. Is it possible to add a shift for each memory? Tnx, 73, Jann
yeah... you have a good point there.. Ill see what I can do. Thanks for pointing this out. JIM ----------------------------------------
