*How was the unit configured, for the wire ant. or the coil loaded antenna? Did you adjust the tuning cap for max output?*
Hi, Neil..
I used the configuration for the wire antenna with the whips. I swapped the cap back and forth for the different situations..
I’ve found that tuning with the whips was easy and the ideal “15 volt peak” could be approached closer than any of the other set ups I’ve tried. I used a fiberglass step ladder to get to the unit but things still changed a little when I moved towards/away from the xmtr. I could see the field strength change also when going up and down the ladder. I just found the happy medium the best that I could..
The power/audio leads will make a difference. They want to be counterpoise grounds and will sure give you headaches when tuning. I posted here a good while back about using an FM xmtr to get the audio to the AM xmtr. (The Best of Both Worlds) This avoids the use of the audio cables, Hence less counterpoise ground to worry about. I choked the crap out of the power cable which did help..
My goal is to set up a self contained solar powered unit to avoid all wiring leaving the xmtr. What I need then is a 25′ “Diddle Stick” to tune the cap.. LOL
I believe when I did testing with the monitor the xmtr was configured for the base loaded antenna. I never tried it with the other cap in circuit..
