David,
Alot of good advice on here.
As a FYI I run 3 Icom HF Radio's and all 3 have the Tigertronics Signalink USB.
There are several good reasons to go this route.
1st - It has its own built in Sound Card. (Does NOT require the PC's Sound Card)
2nd - Only requires 2 Cables to operate ( 1-USB Cable and 1-Radio Cable )
(Some interfaces require an additional Serial Port, Audio Cables and Power Cable)
3rd - It has Front Panel Controls for TX and RX Audio Levels and a Delay control.
4th - PTT is controlled by the Signalink
5th - Powered is supplied by the USB Port on the PC. (NO External Power required)
Also note the Signalink does NOT have a CAT interface for PC to Radio Control)
Digipan is a great program for the new user. Very easy to setup. The program has not been updated and does not support any of the newer Modes or Features.
One program that is just as easy to setup and operate is FLdigi (
www.w1hkj.com)
This program is very well supported and is becoming popular for Emcom work.
Also since you are new to the Digital World I highly recommend looking at the FLdigi Website. It has a link called "Sights and Sounds of Digital Signals". It will show you what a particular Mode sounds and looks like on the Waterfall, everything from PSK31 to MT63 and more. Fldigi is a Modular program that supports Rig Control as well as its own logging program and other programs. Also it has whats called RSID (Reed Solomon Identification) So if a station is running a program that supports it and the TXing station sends the ID the program, when properly configured will detect the Mode being sent and notify you of it and give you the option to jump to the Mode and location on the Waterfall.
Once you have mastered it then maybe move on to HRD/DM780. HRD is a great program BUT requires some good CPU processing Power and plenty of Memory (System RAM) especially if you have other programs running inthe Back Ground. You cant get a much better program than HRD/DM780.
Oh if you are into Emcomm then FLdigi is what you want.
Hope to see you on the Air.
