[TenTec] New Jupiter on its Way _ A Few Questions

[Bob McGraw - K4TAX]

RF issues to a large degree depend on the type and location of ones antenna. 
Certainly an indoor antenna is not the ideal and is far from the better 
configuration but often our circumstances dictate that as the only choice. 
The reduction in power to 40 watts seems to bear this fact out.

No ground needed in my case and I run near legal limit, 160M - 10M, with no 
issues.  The mike of choice is the 709A or the 707.  The radio is the Omni 
VII but my antennas are some 100 ft from the station equipment.  Separation 
works.

As to success with the Jupiter, I think you'll find it a much better 
receiver than the model mentioned.  I suggest the 709A mike for that radio. 
You will likely need common mode chokes on the feedline, power line and any 
other line going to/from the radio.  Also be sure to have a dedicated 
ground/bond between the radio ground terminal and the power supply ground 
terminal.  Do not just rely on the DC power cord for this application.
