1970s CRYSTAL RADIOS            

FIRST SYNTHESIZED RADIOS          

  In 1976 you were a real ham building a repeater from a kit or your heathkit mobile or portable. The ICOM IC-215 and Kenwood TR-2200A were the radio of choice before Hand Held radios were on the market.

Maunakapu UFN operated WR6AVM VHF  Repeater 146.62- pl 103.5 open for public access using a General Electric Mastr II Repeater with 125watts out to a 6db gain antenna with 1/2" heliax. From  2200 feet high above the Waianae Mountain range it is the highest powered Amateur Radio Repeater on the Mountain top. Site is equipped with back up generator. 

Although not related the UFN amateur radio club has allowed the LDS amateur radio group to do net practice on most Wednesday and Thursday nights at 2100 hrs and the public is welcome to participate with their group. 

From higher up west at a back up site  this low power UHF repeater uses a General Electric MVP mobile radio with a Celwave 633-6A  duplexer and Samlex 20 amp switcher for 15 watts output into a 6 db omni providing coverage from Waianae to Honolulu for the American Red Cross.      

From 250 feet above Waikiki the WR6AVM VHF Closed Repeater 147.26+ is using a Motorola Micor with coverage to Hawaii Kai to Leeward Oahu running 100 watts to an Omni antenna.  Echo link with links to the Maunakapu UHF repeater high atop the Waianae Mountain range...
