For the last two nights I have been receiving the Kaguya lunar satellite's
carrier on 2263.6MHz. Using nothing more than an unmodified MMDS, BBQ grill
and PCR-1000 receiver.
My MMDS downconverters have a nominal 1951MHz Local Osc so the IF will be
The problem is that they are filtered for 2300-2400MHz
input and 349-449MHz output. AO-40 on 2401.3MHz was marginal in a
couple of cases.
Despite this, birdies on 312.56MHz and the lousy overcast weather
for the last two nights, I heard the signal shift ~22kHz over an
hour. It was 20dB over the noise according to the spectrum display
and quite audible. Must be the MMDS filtering is poorer than I thought.
For the record:
Equipment:- Pacific Monolithics MMDS, 60cm BBQ grill with flyscreen
mesh, ICOM PCR-1000, DL4YHF's Spectrum Lab software.
