[TenTec] Jupiter - No Transmit Power on 15 and 17 Meters

[Bill Fulling]

Hi Gary,Glad to be of some help.Just remember,don't use a lot of heat on
these little relays when resoldering them in.
This may be part of the problem;I suppose in a jam(like during a
contest),you could "borrow" a good relay from a band that you don't use to
keep you on the air.
