ICOM IC-R71A Power Cord

[Thunderbolt]

I have been searching all over the shack for my owner's manual and I can't locate it. Maybe someone can answer this question for me:

Did the Icom R71A come with a DC power cord? If so, what is it's model number?

Thank you!

Ron,

According to the manual, no. It says to contact ICOM for DC info.....Here is the link to the manual!

That is what I found out, the R71a doesn't have provisions for a DC power cord, but can be wired internally to operate off 13 volts DC. Moreover, later versions like the R72 and current R75, do allow for DC operations with a separate power cord. Apparently, Kenwood foresaw this problem and incorporated DC capability with their receivers.

That's weird, I have an R70, and bought a DC cord for it years ago. Since the R71 was an upgrade to the R70 (added the keypad, voice frequency announcement option and IR remote control, as I remember) I would have thought it would have the same 4 pin DC connection on the back.

The DC operation was an option. was a connector that installed on the back of the rcvr and plugged inside as i recall. Used to have an r-71 and wish I still did!

How sensitive is the R70? I know that people who own the R72, really wish they had a R-71A because its far more sensitive. Likewise, I often read the same about a R75 as well. However, the antenna you use on your radio has a lot to do with it.

The book sensitivity is <0.15 microvolts for 10dB S+N/N for CW, SSB, RTTY and 0.5 microvolts (3 microvolts 100kHz - 1600kHz). My experience with the radio shows that it's a very good receiver that needs a decent antenna. It won't display that kind of sensitivity with just a hunk of wire thrown around the room. My best experience was with a 100+ foot long wire and a good earth ground. I also modified my R70 to enable the preamp below 1600kHz. Although it can overload with nearby strong AM stations, it really helps dig out the beacons below 500kHz.

I use a normal computer system unit power cable on my IC-R71A with the 3 female connector.
works fine! It's AC only
