My Maxtrac decided it wasn't going to hear anything.
So start at the antenna and work my way towards the speaker.
I got the 45.1 MHz IF going into the "receiver subsystem IC" but I don't have any 44.465 MHz from the crystal Y52.
Injecting 44.465 MHz with a signal generator and scope probe makes the radio happy so at least I know everything else is doing what it should be doing.
Of course, the Xtal 44.645 MHz PN 48-80008K02 isn't listed anymore in the online parts book. (Of course)
Is there a cross reference to something they do stock or does someone here have an old one in stock on the shelf they want to sell me?
Thankies

Hello:
A fellow on ebay is selling 2 new 44.645 crystals with free shipping for 8.99
Don't know exactly what the deal is but I heard that a company was making the crystals after market.
Ebay auction number 271251635200 seller = winterallsweet2013
Not saying they are good but cheap enough that your not out a bunch.
He did get a positive on a sale of 2 crystals already sold so its your decision.
Good luck

And if that doesn't work, I bought a used complete radio for $27.00

The crystals arrived today. After cleaning the gunk (adhesive) off of the board and soldering in the new crystal the radio sprang to life.Satelite wrote:A fellow on ebay is selling 2 new 44.645 crystals with free shipping for 8.99
