[TenTec] Weird Jupiter Xmit Problem

[Jack, W7EJJ]

Hi George:
    I have completely isolated everything. My grounds are OK. It is
definitely the Jupiter and I still think something is wrong with it, but if
TT service says not then it's no longer my problem.
    By the way I might add I'm a retired Radio Engineer (Microwave)
commercial FCC license with ship radar endorsement, lots of experience in
Signal Corps with Fire Control Radar & Microwave, spent many years in
commercial 2-way radio for governmental entities (as Communications
Officer), Radio Engineer (Microwave 2 & 6 GigaHz)  for Ariz. Public Service
designing, installing, maintaining mountain top microwave repeaters which
controlled all our power plants (6), substations, lines (340Kv & 240Kv) from
Phoenix and finally Avionics (Lockheed, Boeing & Douglas). So I think I
probably more capable of diagnosing a problem than those guys in service at
TT.
