[NLRS] uW Tune up this Saturday

[Donn, WA2VOI]

To follow up on Jon's note earlier ("NLRS Breakfast and uW Tune Up"), the kinds
of things we'll try to measure:

IF Radio:
power out, Frequency, and
Mic gain (or Data gain for WSJT, etc.) to provide clean  signals w/o splatter
TX stability

XVRTR:
Frequency, power out, RX and TX gain
TX Stability
Pre-amp: NF (?)
Cable losses
Ant feed Return loss (but NOT gain -- no antenna range)

System:
Sun Noise
Pwr amp output
We also want to try to take a look at system degradation when multiple operating
frequencies are in use at the same time and location.  What minimum freq
seperation is needed; what effect, if any, does the use of XTAL vs PLL LOs have,
etc.

Try to remember to bring the manual(s) for your i.f. radios so we know how to
access and change the mic gain/dat input gain settings.  Likewise for the Hi/Lo
power settings.  Same kind of date is needed for your XVRTR to adjust the TX and
RX gain settings.

Bring your whole system, including tripod and DC power both for the sun noise
measurements and system degradation.

This can't be a "repair" session... that takes too much time per system.  The
best we can do is make minor adjustments and identify big problems so you can
work on them later at home.

See you then.  Hopefully, it will be a good morning/early afternoon (sunshine
and a --mostly-- clear sky).
