Did I not tune it well enough or is there something other than the 5 tuning screws on the front of the receive card. Also, after carrying the quantar back to the shop I got a receive card fail. I opened the card and there was a loose metal piece inside. Now the receiver module does not work. Does anyone have a fix other than purchasing a new card? Does anyone know the cost of a new receiver module?
I think we've got insufficient information here...
What did you use to tune the Quantar? Did you use a real service monitor? If so, what receive sensitivity did you come up with? At what level does squelch open? At what level do you achieve 12dB SINAD?
A new receiver is several thousand dollars at minimum new from Motorola. What does the metal piece look like? Can you provide pictures?
Every Quantar I've ever had to tune up consisted of injecting an on-channel signal and tuning for maximum receive sensitivity with the front tuning slugs, and then adjusting squelch for proper levels, followed by setting the RSSI level according to the RSSI calibration screen.
Transmitter consists of setting proper power output, proper reference frequency error, proper modulation compensation, and proper deviation.
I set wireline levels appropriately using a transmission impairment measuring set and verifying proper wireline I/O audio levels.
The only thing I actually physically adjust without a PC is the tuning slugs on the front.
Sounds like your receiver physically broke. You didn't drop the station did you? Digital pictures would be a big help here.
