[TenTec] Jupiter intermittent receive

[Steve Cochrane]

I keep re-discovering how different radios respond to bad connectors and/or coax. One radio may seem to work OK but another radio will not. It appears to be especially bad with the cables that us lazy people buy at hamfests that have the molded connectors. I find when I screw those on I have to keep wiggling them and tightening until there is no more wiggle.
Just sayin. :-)

Hi Lars,

I doubt it's a bad connection between the radio and antenna. I have a Drake TR7 which works fine when I swap the coax from the Jupiter to the Drake.  Maybe it's time to put the Jupiter out to pasture and stick with my TR7's.
