The AMARC High Ridge Past Equipment and Attempts
Replacement of the High Ridge Multi-Band Multi-Mode radio in 2Ø13.
Our newest change was to replace our FT-1ØØD radio on our High Ridge Multi-Band Multi-Mode to a FT-857D radio.
The reason for the change was to improve the Remote Base to handle more channels, faster channels change, and have better AM modulation.

Here is the information of the ICOM R-75 Receiver. Bought it in 2Ø11 to improve the 6 meter reception.

Modifications to the UHF and VHF Amplifiers
The RF amplifiers was removed from all the High Ridge repeaters in 2ØØ7.
They become a big maintenance problem, and at that time we decided to put backup batteries on all of our repeaters.
The amplifiers was designed without RF relays to allow the antenna connection to the RF input connector with no power.
Without the amplifiers the repeaters have 4Ø watts on VHF, and 3Ø watts on UHF.
The only RF amplifier in service, is the Barnhart 6 meter AM transmitter with it's 150 watt amplifier, and it has been doing well.

All of our newer repeaters were built between 2ØØ6 and 2Ø13.
The new repeaters replaced our old club's 146.925 Remote Base repeater system.
It had a 1Ø meter and a 6 meter GE Master-Pro Simplex FM radios as remote bases on 29.6ØØ, 29.5ØØ and 52.525, 52.54Ø mhz.
The remote bases frequencies could be switched with DTMF codes. This repeater was used from 2ØØØ to 2ØØ6.
