[ARC5] Using SCR-274N

[Bob Macklin]

I have no interest in "DX Wallpaper"!

I would just like to see some useable HF AM here in the PNW. I would also 
like to see some 40M AM.

Back in the 60's I had an ARC-3 pair on 2M AM. I also played with the ARC-5 
VHF sets. I would like to see some 2M AM activity here also.

Has anyone ever seen an ARC-3 on eBay?
