15 June 2008
Upgrade Trip
N5HYD - KA1AAJ

Repair Trip
KA1AAJ
  • 145.230 LOCAL REPEATER:
    • Int. transmit audio. Loose connection on the SAS board, J8. This is the radio speaker connection. We are not sure if this connector causes the failure.

Repair/Upgrade Trip
W5ATO - N5HYD

  • 443.000 LINK RADIO:
    • Well, the Motorola Radius SM50 #682FXU4254 was missing and is presumably being used as a Link Radio at the 444.900 site. Installed a Motorola Maxtrac.

    • Replaced 2 audio pots with 200K, 25 turn pots.
    • The two TONE pots are stock.
  • SITE: Aligned.
