[hpsdr] Trimble Thunderbolt & Excalibur

[AA8K73 GMail]

My Excalibur oscillator was 10.5 Hz off at 10 MHz
against WWV and my Trimble Thunderbolt, after a
10 hour warm up.  I waited another day and zeroed it.

I haven't touched the adjustment on the TXCO but if my Tbolt is working OK then the TXCO on my Excalibur is out by some 10 or so Hz as the phase lock LED is alternating red/green at that sort of rate.
