Re: Topband: BAD OT:Phase noise *** RE: digital on 1838 +/-

Phase noise is generated by the rig's LO and exists as a more broad band low level signal. Issue is more significant with modern day DDS than with older analog-type VFO sources. Guys who operate field day can relate... 73/jeff/ac0c Don't you mean IMD from the radio/amp driven past ALC? CW is

I was under the impression that JT65 was a weak signal mode. 600 watts seems a lot for that. Is that a normal power level for that? I was hoping to work it without an amplifier. Darl NA8W -- From: Jim Brown j...@audiosystemsgroup.com Sent:

You certainly don't need an amplifier for JT65 and most are not using them. I worked half a dozen stations last night on 160 - mostly new states from here in Florida - using nothing more than my 80/40 trap inverted V and 100 Watts. Worked KH6SAT on 80 with the same antenna and power level ...

Would that FCP work with my 43' vertical, three 25' top loading wires that drop at a 45 degree angle (patterned after the NORD antenna model) and have a 160 meter loading coil that I put in series with an auto tuner at the base??? Using a less than complete counterpoise field - about 40

Re: Topband: More Inv-L matching issues.... BIGGER ISSUE

Dan A couple of thoughts... When transmitting, is the RCS-10 antenna switch inadvertantly changing (switching) antennas (ports) during the transition from receive to transmit, possibly RF getting into the switching circuit causing this ? Do you lose the 12VDC to the switch when changing from

Happy New Year to all Jim, I'd love to have you as a neighbor. You know how to set up a station for best performance. I had experience with some stations in my area that wants to get long DX increasing power without knowing how to do it. I was able to hear the guy on several different
