[AK-VHF] New 222-MHz Radio

[Edward R Cole]

I decided to sell my DEMI 222-28 transverter to W7YOZ in OR.

I bought a new Bridgecom BCM-220 30w FM transceiver.  I can bring up 
224.94 repeater (70miles) with 30w.

I will eventually interface the BCM-220 to use my 150w Securitor Amp 
and my tower-top preamp.  I purchased a DEMI sequencer board which 
will control preamp/TR relays/amp/radio PTT.  I will use a spare TR 
relay in the shack to select either preamp (Rx) or amp (Tx).  Amp 
requires 12mw drive so I will run the radio at 5w into a 10w 20-dB 
attenuator followed by a 6-dB attenuator at amp input:  5,000mw/400 = 
12.5mw drive.  The preamp has a separate coax run which will connect 
thru the TR relay in the shack to the radio.  I'm guessing to run 
130-150w with this when its completed (in June, probably).

Radio is on and scanning 223.53 & 224.94 using two 11-element 
CC-yagis at 60-foot (pointed at Anchorage).

June ARRL VHF Contest is June 10/11: http://www.qsl.net/a/ak-vhf//Contests/
