Repeater Testing

Tuesday eveining, September 30, Dave Powell-Williams (VE7MQ) came over to do some testing on the repeater. He spent around an hour running the system through its paces. He found the receiver to be quite sensitive better than .2 micro volts, he found the receive side of the cavity to have good performance. He determined that the antenna was doing a fair job though the coax was somewhat lossy. He then checked over the transmit side of the cavity filter and determined that it was not in tune. We are getting about 53dB of seperation rather than the 80+ that the unit can deliver. This is giving us 11dB in de-sense receiver loss which as you can imagine is quite serious. So we will need to find someone who can tune a finicky old cavity! Stay tuned (sic) for details.
