06/18/07 initial notes:

I started working on the Original 146.91 repeater. I am preparing it for temp use to hold onto the 147.03 freq coordination.

 

Some initial notes:

• T/R relay still in place and operational? It was NOT bypassed, it was still operational!!!
• Soft jumper from PA board to the T/R board was hard and cracked.
• Receive line was to short and in poor shape.
• Hielacle filter section IS NATIVE ON the HAM BANDS!
• Oscillator is native for the ham bands!
• Receive sensitivity was only around -120dbm (approx), should have been -135dbm or better.
• Three transistor PA? 75watts?
• A repeater Controller board was found to be controlling the Radio.
• Crystals were from an unknown manufacturer, Mounted in NON-TEMPERATURE Compensated 5C Icom's. Solder job was a good one though. I will store these as Spares. They were pro-made I suspect.
• There was NO PL deck in this repeater? ($75 to do this right)
• Exciter was on freq and on the ham band! 300mw out.
• There IS a RAB (Repeater Audio Board) so it will be easy to remove any user introduced PL tone.
• Found a 120volt AC Fan on the insode cover of the PA!?

So in general NO MODS will be necessary. This is my plan

-        Krylon the Hielicles. (May be deferred till later)
-        Remove T/R relay.
-        Cut out wasted wire. (May be deferred)
-        I should bypass AMP connectors for reliability (May be deferred).
-        Wire in controller connections.
-        TUNE (need to borrow N1FGY sig gen).
-        New Fans (means making a new Fan Controller board and brackets!)
-        Put into service.
