This is the latest marker project interest list. The numbers are looking
good. The count is 15.

Presently we are getting quotes for the Ref. oscillator. This is the major
cost item.
Joe (KI4NPV) is providing a 48 MHz source to test preliminary circuit
concepts.
Here are the most solid features desired to date:
1) Operate from 12v and as low of current drain as possible.
2) Research best Ref. Osc. possible verse quantity and price.
3) Built-in 100KHz offset marker with additional AUX input. *This offset
feature is a DSSB mixer on the output. You can call it an AM modulator,
if you wish, by also generating a 1KHz offset too. Any interest?
4) Provide markers for the harmonic related band 1296 thru 10 GHz plus 144
and 432.
5) Some form of signal level control. If we can't provide control, being
able to calibrate to a known level, may be sufficient. User provides
attenuators.
6) A handle on top.
