I think I've told this story before but I am still stumped.
Station is as follows:
Icom IC-7100
LTG AT1000 Pro II tuner
80m OCF dipole about 40 feet up
50 feet LMR400 feed line going to a lightning arrester on the house.
10 feet of LMR400 from the arrester to the tuner. 3 feet LMR400 to radio from tuner
PowerWerx 25Amp switching power supply plugged into standard 110v outlet via a power strip.
All gear is tied to a ground bus on my bench which is in turn connected to a ground bus on the side of the house which is tied to the ground rod buried next to the house. I've verified continuity of the ground as best as possible. Can't really verify continuity between the buses because of the length of the cable run...but I'm pretty sure it is fine.
The grounding has resolved an RF issue I was having with my amplifier effing with my radio's settings. The amp is not in play here as the problem predates the addition of the amp.
House
100 Amp panel with a sub-panel for the ACs (2 units - Air handler/compressor). Air Handler is 110v and compressor is 240v. York brand units.
When I operate down on 80m, say at 3570khz or 3576khz and transmit at 100W, a couple things happen:
1. Lights throughout the house flicker slightly while transmitting
2. The air handlers cycle up and run the fan for about a minute.
I'm assuming I need some type of choke to eliminate the RF affecting the air handlers, but I'll be damned if I can think of a place to put them as they are hard wired into the panels.
Is choking the correct path forward?
Thanks
