Rig: Icom 718.
Interface: Rigblaster Plug & Play. With the Icom 718 it requires an 8-pin DIN to 13-pin adapter. The 8-pin DIN plugs directly into Yaesus such as the 897 or 857. Also requires a cable for CI-V or rig control, 1/8" mono plug on the radio end (plugs into "Remote" jack) to 1/8" stereo plug on the other (plugs into Rigblaster P&P's Rig Control jack).
Soundcard: iMic. Since the laptop I am using has no Line In / Line Out, I'm using the iMic, which has 1/8" stereo jacks and plugs into the computer via USB.

I use the iMic also for recording LP's via Line Out (or "Tape Out") jacks on my stereo system via my laptop. I then run a pop/click filter, and then burn to CD, and archive the rare and irreplacable LP's.
Digital Software: Ham Radio Deluxe and Digital Master 780. HRD is their rig control software, DM780 is the digital program.
Problem, Icom 718 lacks the TX command in CI-V, so though DM780 produced the digital signal, the radio would not go into TX. I worked around this a bit by clicking Send or Auto button in DM780, while pressing the PTT button on the mic. This was not cool.
This is not just a problem with the Rigblaster Plug & Play, it has been reported with other interfaces, and similar problems with other radios.
I finally found a workaround. Simply don't use Ham Radio Deluxe. Why do you need it? The radio is right there, lotsa buttons and knobs and stuff right on the front of the radio. You can work the radio without HRD. Seriously, I would like to take advantage of some of the features in HRD, and I'll keep looking for a solution to this problem.
There is a conflict between the Icom 718, HRD, and DM780 that keep it from working PTT. Solution for now, don't start HRD via the desktop menu. Yeah, I had been starting HRD, then in there, clicking the DM780 button on the toolbar to start DM780. I went into the start menu, Right Clicked and copied the DM780 shortcut icon in the HRD folder, and pasted to the desktop. Start ONLY DM780.
At the top Tools > Program Options > Soundcard tab, make sure the iMic (or whatever sound card you use) is selected for both input and output devices.
Now in Program Options, PTT tab, under COM Port in the upper left, check "via Serial (COM) Port", by "Port" in the drop down select your Rigblaster's COM port (you can find this in the computer's Device Manager), and below that, check both DTR and RTS.
Now the Icom 718 will go into TX when you send.
On the Icom 718, set the power by pushing the SET button, turn the tuning knob to the right to full power (indicated by "H"), push SET again.
Set the TX audio level to about 50%. When you transmit, with the SET button the radio, toggle between Power, SWR, and ALC. When it transmits you want power to be about 20-25 watts, and NO ALC to indicate on the meter. If ALC is limiting, you will have some distortion and spatter all over the band, making other hams very unhappy with you. And your signal will be unreadable. So, adjust the TX audio level, either there in DM780. Click Soundcard button on the toolbar, check TX, and adjust the slider up or down to set the TX level. If you want to reduce power, don't do it on the radio, but do it in the audio level. This will give a nice, clean, easy to decode signal.
In all bands, set the radio to Upper Side Band. Frequencies, 3.580 mhz, 7.070 mhz, 10.140 mhz, 14.070 mhz, 21.070 mhz, and 28.120 mhz. USB all bands, even 80 and 40 meters. For the Icom 718, normally in 80 and 40 meters the Mode button will skip past USB. Just press and hold the MODE button about 1 second, and it will change from LSB to USB.
So, that's it. I made QSO's with NY, VA, CO, Ontario, Canada, Mexico, Quatamala. With 25 watts... about what the lightbulb in my fridge draws. Amazing!
