I had problems on AO-40 several years ago. The problem was traced to the connection of a silver plated brass connector bolted to an aluminum surface where crossion had set in. Cleaning the connection stopped the 70 cm uplink from crashing my 13 cm receive.

Same here with TS-2000, 6ft *aluminium* boom and SSB Electronics masthead pre-amps.
I'm thinking about a 6ft to 9ft fibreglass boom anyway, I would be interested also in user comments.

I got significant de-sensing of my 2 meter downlink from my 70cm uplink at Field Day. I know a good part of it was due to the short cross-boom (about 4 feet) I was using. I would like to decrease the de-sense on this set-up before I permanently install it at my home station. Any and all suggestions are welcome.
