Re: VARA FM Kenwood D710g Ext 9600 not working
Matt,
I have moved jumper. I think volume is the key.
are you able to work VARA FM at 9600?
I set the RMS to 9600 also, seems to work 1200 too.
thanks loads.

yes I got that, but still nothing. thanks

Re: VARA FM Kenwood D710g Ext 9600 not working
Mark, menu 601 is for the TNC, which we don't use with VARA FM,
we use data port.
which I thought was in 900 menu settings 919
but Ill try it
thanks john

Re: VARA FM Kenwood D710g Ext 9600 not working
John;
Menu 601 - DATA SPEED needs to be set to 9600

Re: VARA FM Kenwood D710g Ext 9600 not working
When you switch the radio from 1200 to 9600 the audio goes out a different pin in the back of the radio.

Re: VARA FM Kenwood D710g Ext 9600 not working
John,
I believe the Kenwood D710 is changed between 1200 and 9600 baud
operation in the radios menu system (selected in software).? It's
possible that 1200 or 9600 audio comes out the same pin on the
radios DIN connector, and switching it in software makes the baud
rate change.? This is not the normal way many data capable radios
handle the two audio types.? Many radios have BOTH 1200 and 9600
audio available at the DIN connector and moving the mechanical
jumper on the DIN-6 adapter physically switches between the two.?
If my assumption is correct, and baud rate is changed in the
radios software, then the 1200 / 9600 jumper on the DIN-6 adapter
(or DRA-36 or DRA-50) might have to stay in one position.? Which
one is unknown, but maybe 1200.? That's probably why nothing works
when switching the position of the mechanical jumper to the 9600
position, but this is only speculation on my part.? The manual for
this radio is so poor - I can't even tell how the data terminal
port is wired, never the less how it's supposed to be configured.?
Maybe someone that actually has one of these radios can explain
how it works - because the manual isn't doing it for me.

VARA FM works very fast at 1200...
but has anyone set Ext 9600 using VARA FM?
The only way we can get it to work so far is with EXT baud
rate??set to?1200?.?
?Kenwood TM-D710g Menu 919
I have everything set to 9600, DRA-30
board pin 9600, including RMS and wide FM.
Except when Ext baud rate 9600 is set
it does not work, only ext 1200...
Go figure.

Re: VARA FM Kenwood D710g Ext 9600 not working
I have a D710G.? A different pin is used for 1200 baud (narrow) vs 9600 baud (wide).? If you are using the din-6 adapter from Master Communications then you just need to move a jumper.? If you are using a DIN-6 to DB9 connector you will need to change how it is wired.? I have also found that I have to turn up the volumes to make it work as well when set toe 9600.

Re: VARA FM Kenwood D710g Ext 9600 not working
John, Describe the cable between your RA board and the Data Port on your D710.
What wires have you connected on the DRA and D710, and to which data port on the D710 are you plugging in?

I upgraded the cable from the radio to the Signalink to CAT 8 and in the spirit of overkill I added RFI suppression with an FT-240-43 torpid. I use the link on 6m FM.

What cables did you upgrade to CAT 8, the Ethernet cabling??

Dang, now I'm going to need to get one of those.? The little adapter is a bit janky.

I would get a DRA-36 (not on the website yet, but contact Kevin), and then use a cheap 6-pin to 6-pin PS/2 type cable from Amazon. Those cables are so cheap, just get another one and cut the connector off one end and add whatever connector your HT needs. This is a DRA-50, same idea as the DRA-36 (uses a 6-pin DIN instead of the DB9):  ? -Scott, NS7C

I would just use the DRA for everything. Unmodified, the Signalink is pretty ugly in the low end of the audio spectrum (do a google search on Signalink Mods). I rarely use mine for anything anymore. You really do not want to have both devices connected together. With the transformers in the Signalink, you are going to do strange things to the input and output impedance, which will will probably make both devices perform much worse.

Re: DRA-30, Audio when radio configured in 1200 baud mode, no audio when configured in 9600 baud mode
Correct. I use a cheap ($5) PS/2 type cable from Amazon for the radio cable:  -Scott, NS7C

Re: DRA-30, Audio when radio configured in 1200 baud mode, no audio when configured in 9600 baud mode
Scott,
Re the DRA-50¡ So you build one cable with both the 1200 and 9600 lines going thru and then jumper in the DRA as to what speed you want? ? Din 6 on each end¡ depending on the radio.
Our local guys running the Kenwood 710s found the same thing. ?Need lots of audio to drive the 9600 baud.

When using the "9600" pins on a radio you are connecting directly to the receiver discriminator (not bypassing it) and the transmitter modulator. It generally takes a lot more drive when you are connected to the modulator to achieve the desired deviation. Some manufacturers point this out in the manual, most do not. The "standard" 6-pin DIN connector is anything but "standard". The pin assignments are the same between manufacturers, but the levels and impedance of the input and output vary widely between manufacturers and even between models from the same manufacturer. On some radios the DRA-30 cannot provide enough drive to the modulator to achieve proper deviation. That's why there is a DRA-45, which includes additional amps for both input and output. There will soon be a DRA-36 and DRA-50 which have 6-pin DIN connectors and "1200"/"9600" jumpers on the board, eliminating the need for the 6-pin connector board.

Re: DRA-30, Audio when radio configured in 1200 baud mode, no audio when configured in 9600 baud mode
OK, I cranked up the volumes and that seemed to do the trick.? It is interesting the difference in volume levels between the two settings on the radio.
Thanks again,

Re: DRA-30, Audio when radio configured in 1200 baud mode, no audio when configured in 9600 baud mode
Mat,
In the VARA FM settings, Vara Setup, FM settings to Wide? ? ?Level all the way up on whatever channel (L or R) on the DRA30 ?you are using? ? Sound card RX level (L or R) up to at least 50%??
My best guess.,

I have two DRA-30's with the DIN-6 Connector board attached to a Kenwood D710 and V71 for testing.? I have had good results testing VARA-FM in narrow mode with each radio having their data port configured in 1200 baud mode.? I now want to start testing Wide mode.? I configured each radio's data port to 9600 bps which should adjust the audio path to bypass the onboard discriminator.? I also moved the 1200/9600 pin on the DIN-6 Connector board.? It doesn't matter which radio I try this on, when I press the tune button on the SoundCard menu in VARA I see the radio key up but I do not hear the tone I normally hear when the radios are configured in 1200 bps mode.? I have check the cables for continuity and I have checked the DIN-6 connector board for continuity between the appropriate 9600 bps pin and the board.? All looks good there.? In VARA the Audio Input meter is showing signal as well.? I don't have any of the pins jumpered on the DRA-30 if that matters.? Thoughts?
