[Kenwood] TS-820(S) relay

Sun, 2 Feb 2003 19:26:14 -0800

I was in the first half hour of the Sprint on Saturday when the T/R relay on my TS-520s got really stuck.  It's the same Omron MH4P unit.  I'd cleaned it once before, but that fix only lasted a week or so.  I swapped the relay from my 820 (which seems to be turning into a parts rig) but didn't get back on the air before child care ended my participation in the contest.

A web search on Google found the relay at: http://www.kenselectronics.com/lists/relays.htm with a substitute for $9.00.  I know nothing about this company, or if the substiture is really a direct replacement.

If the VFO-820 has the same relay, I guess I'll canabalize my parts VFO (it jumps frequency like crazy despite all my attempts at cleaning everything in sight) and get the 820 back to it's slight-drift-with-no-rit state.

Please let me know if you find a good replacement relay.
