This morning I did some better experiments and set the IC706 up on a dummy load and placed the ICF-2001 receiver close by to the dummy load. I was easily able to detect the keying on the receiver, so that was excellent news.

The next challenge will be to find some sort of antenna matching arrangement. I have ordered a ferrite rod from eBay (despite trawling through my junk boxes in the loft, I couldn't find one). My first attempt at an ATU will, I think be similar to Roger G3XBM's - although more of a bodge I expect!
However, I was speaking to Adrian G4GDR yesterday on 2m. Adrian has been one of the 500khz permit holders and mentioned that he had made a variometer out of a carpet roll and some rods. He very kindly invited me to inspect it, which I will certainly do.
I'm not sure how viable the IC706 will be for 472khz, but perhaps it will be possible to scrape a local contact or two.

I do follow this post with interest as I use a Icom 706 myself. I even got that Sony SW receiver ;-). Didn't know the Icom is able to produce a signal on 472 KHz. 73, Bas
Hi Bas. It's definitely worth a go! Probably best to keep the power quite low, but I can see 2W into a dummy load at the lowest power setting.
I don't yet know how good the receiver is!

A receive convertor with an IF at 160 or 80 meters would be helpful
You can manually switch the radio between receive and transmit modes.
