I came across this: " rpitx " it is python software that enables a
RaspberryPi to transmit using a GPIO pin.
The links refer to using the Rpi to produce 2m Tx signal. Rpitx seems
able to produce most modulation schemes. I have not tried it so have no
idea if it would produce your need direc

I have a '50AA here. But I don't use any command line options relating to
box ID. Just start up LH - LH talks to the box, determines it's a Trimble
variant, and off to the races it goes.

I tried /rxt but that won't communicate. Must I put the unit in
Thunderbolt mode?Is there
a jumper or a command that will do it? The manual that I have does not
mention different
modes. It only talks about SCPI.
Thanks,

To answer, both Copper and Aluminum cavities use the temperature setting
to coarse tune the cavity.
Fine tuning is via Varactor diode and modern Masers do servo "Auto-tune"

The Nortel devices can talk either as a Thunderbolt or as a SCPI device. Use
it as a Thunderbolt (/rxt). In SCPI mode the satellite positions are polled
for once a minute (at xx:xx:33). Thunderbolt mode provides much more and
better control of the receiver.

Your explanation is clear and lucid, in contrast to some earlier attempts
here. I agree that with oscillators the distinction between N and N-1 is
not particularly relevant. I must caution you, however, not to be too
dismissive of the difference between the two. The

I have a NTBW50AA running with Lady Heather 5.0 (and also with previous
version) and I don't see any anomaly, it sees all satellites in view and
the clock updates every second. BTW, I have done a mod for outputting 1
PPS instead of 1/2 PPS, but it does not go to LH.

What am I doing wrong?
Also, the clock updates every 2 seconds. I assume that this is
Sorry, I missed the "complete unit" part... the TAPR products do require
some soldering. The TADD-2 does have a case available if that helps.
