Hello Steve:

Ok, your explanation was very good and have Pinpoint configured I think. VaraHF modem SW is of course working ok. My GPS shows up on Pinpoint too.

Where else would the GPS show up? ?? If you are not operating mobile (i.e. not changing position), you don't really need a GPS connected anyway - just hand-enter your latitude and longitude into PinPoint or other APRS client.?

Now I need to get pinpoint to interface with the Icom 9100. What piece of software is used? "UZ7HO Soundmodem"?

NO!? The Soundmodem is a conventional packet TNC in software - completely irrelevant to operations with VARA.? [NOTE that you might want to use the Soundmodem instead of VARA on 2M VHF to take part in conventional packet APRS on 144.39 since the IC-9100 is a "DC-to-light" HF/VHF/UHF radio.]

VARA is your software modem.? It uses a sound card (either internal to the computer, or an external one connected by USB) to generate data tones on TX and to decode data tones on RX.? You need to connect the soundcard output and input on the computer,? to the radio's rear panel "DATA" port.? The IC-9100 appears to have two such ports - the industry-standard 6-pin mini-DIN port -and-? a full-size 13-pin DIN port that is proprietary to Icom. ??? You will need to make up (or acquire) an appropriate cable to connect the interface to one of these radio ports.?

You will also need a USB cable to connect a USB port on the computer to the USB port on the Icom,? for PTT keying.??
????????? -or-
skip the hassle of dealing with virtual com ports created by USB-to-serial drivers.? Use a tone-activated interface like a Tigertronics SignaLink USB.? This device has it's own built-in soundcard and a VOX-type circuit that automatically keys the transmitter whenever VARA or other soundcard digi-mode generates a transmit tone.?

I'm going to need to direction about this part.?

Thanks,

AL7PX
