[time-nuts] Microsemi XLi SAASM

[kb8tq at n1k.org]

Hi

Just a guess, but I'd bet the answer is no. 

The only reason the SAASM receivers play with L2 is to demodulate the encrypted 
military signal with the proper key. There is no need to do the "fake out" reception
that the old style survey receivers did on L2. With no need to do it (and likely no survey
data interface to report the results) .... no function in the device. 

That's just a guess based on no direct knowledge of what's what with the device.

Bob

Hi Mike;
Quick question, do the SAASM receives work as simple L1-L2 standard recovers without the Key?
Sadly there is no company more protective of their product information then Microsemi.
Sadly Microsemi is clearly in the camp of stockholder driven rather then customer driven.
I have spent decades looking for a service manuals for the 1050A and 5071A with no luck.
I feel sorry for many of the employees that have worked there for decades and are limited by the short sighted policies limiting the sharing of information in recent decades by so many test and measurement companies.
Thanks;

Tom Knox

Steve,
There is no jumpers for the antenna voltage.
I have 2 saasm units and have many Xli units for parts which I would sell
Thanks, Mike
Some time give me a call and I can help what I can.
Very Best, Mike

Absolutely, but I’m hoping the XLi, like some of the later receivers, has a method to select the antenna voltage.
