I have 40m RFI issues inside the RV (motorhome) when transmitting
I use a Ameritron ALS500 linear amplifier
This is observed during CW or DIGITAL or SSB
1. 12V car audio speakers - cycles on/off when i xmit
2. 12V water pump - cycles on/off when i xmit
3. 12V refrigerator - cycles on/off when i xmit
4. 12V air conditioning thermostat - cycles 110VAC on/off
In an attempt to fix this
I installed snap on chokes (from http://www.radiodan.com/Henry/parts/RF_chokes.htm
) with two turns of both speaker wires. Still RFI....
I haven't done that for other 12V appliances.
What else could i do?
Did i not select the correct RFI?
Do i need more chokes or more turns of wire inside the choke?
