Hello Mike,

The good news is that DUV works with the IC-910, no mods.

For the IC-910 you need to use the same port and pin as used for 9600 full duplex satellite mode packet. I *think* it's MAIN data port pin 4----but do NOT trust me :) Too many radios, and too many flip-flops of main vs. sub on the different radios. Make sure menu settings are proper for 9600 satellite packet, too, or the audio won't be coming from the right source.

Another HUGELY important matter---the sound card you are inputting into. With the IC-910 at my QTH, the built-in sound card in the PC motherboard works pretty well, using Line In. However, an external Apple USB audio dongle device will NOT work--it cuts off the lowe frequency and won't print any telemetry.

So, even having the right port and pin isn't enough--make sure your sound card works, too!

73,

I am trying to get the DUV telemetry working here. I have the Audio from my IC-910H ACC Socket (Pin 5 AF) feeding my computer with no luck on decode. Should I be obtaining the audio instead from the Data output 9600 pin 4?

Thanks

Hi MIke,

Yes, you certainly need to take it from data out. Normal audio will filter out the lows below a few hundred hertz, and that is right where the DUV data is. Check the specs though...sometime rigs take out all filtering on 9600 baud packet. Some take out only the filtering on the high end. So you may have to hack a wire in on the other side of all the filtering.
