Repeater Question Scott860 1 week, 5 days ago
There are several places you can try. Look up your states frequency coordination group. Information can also be found on radio reference dot com. Or Google repeater frequencies for your city.
Relay with FT 857 KB3YKT on 13/8/17
Those relays appear to be RF relays. Exactly what are you trying to switch?
Tyying to understand parallel dipoles. AC2MM on 23/7/17
How does the Alpha Delta differ from the fan dipole other than the loading coils to shorten the 40 meter band?
Power line transformer interference? jmayer180 on 18/7/17
The first concern should be safety. The antenna should be mounted such that ANY combination of failures of the antenna supports or antenna wires don't allow the antenna to come in contact with the pole, transformer, or lines plus 10 feet (or more!).
FT-7800 Transmit Error? N6HAM on 14/7/17
What frequency are you trying to transmit on? You may have the offset set wrong causing the radio to transmit out of the band.
