i've put together a saber IE UHF (440-470) with an 8K display board. i have one display board that was previously programmed (for same type of radio), and one that is new. the new display board results in a dead radio. the previously programmed display board results in a radio that emits a soft click from the speaker when turned off, but it's otherwise dead. saber rss R07.01.00 won't read or write the radio with either display board...just a serial I/O error as if the radio wasn't even there. main board, all modules and housing were from a good radio; all flex, controls, and hardware is new. tried two batteries, both new and charged. display boards were removed from or intended for the same model saber. any ideas?

saber IE UHF 'click of death'

4-pin reference oscillator is a NXN6269A 2ppm and brand new. reversing or removing it causes radio to go completely dead (not even a click). so lets say it's likely OK for now. <--not cheap to replaceOn 2002-02-27 18:33, N4UMJ wrote:
Check your 4 Pin Oscillator Module.
This has got me more times than once.
Just verify the ground Pin goes to the ground pin on the main board.
Keep us updated,

as for checking ground (from main board to battery contact?), which pin is it? i can't find pins 13-16 from the main board labeled anywhere in my service manual. looks like 1-12 go to the universal connector, but 13-16 just get lost somewhere.
Your Ground from the battery goes straight to the chassis throught the two threaded studs in the bottom of the Saber.
As for Pins 13 and 16 they are labled as NC which stands for "No Connection"
Pins 3 and 6 plus ground from the RF connector on the accessory are needed to program the Saber. The Ground from the Accessory Connector goes straight to a screw on the rear Radio Cover Plate. This should be tight also. I have broken this little "U" shaped affair before. :'(
Not too sure what else to tell you. Maybe try a new or different casing. Maybe your flex cable inside the casing is bad. Also be sure the spring contacts on the bottom are not bent inward to the point where they do not protrude far enough to make contact.

One step at a time I guess.......

Hopefully they are in the forward direction.
Good Luck on the radio listening to the computer...
I tried to get my computer to recognize my 8K 1E display and it insisted it was a 2K. Wanted to go further with this but ran out of time and patience. Think you have to stop programming in mid-stream to do so. Sounded a little risky to me.
