IC705 USB Cable Choke

So a quick update, having received the 5M USB cable and cable ties, i then went on to test out the choke method to reduce/remove the inteference from the IC705 as shown by Temporarily Offline Ham Radio video included yesterday.

The RF Choke comes from here, as I dont suffer RF back into the shack thanks to the EFHW and RF Choke on the feedline, the PSU Choke was not being used. Winding the toride was made quite easy by the fact the choke can be opened up and wound up, once secured with a a couple of cable ties it was easier to put the turns into specifc locations, tighten the cable wraps up, then cut off the excess.

WSJTX in action – no sign of disconnects or loss of audio

I tested MMSTV and WSJTX into the 2M Comet Whip antenna, everything worked fine with no issue of disconnected audio or interference into the radio or the computer. I’m looking forward to taking the setup out and trying again with the Toybox whip antenna to see how it does this time out.
