I know the feeling!

My Philips I2C TV tuner module (40 to 900MHz approx) and I2C controlled=20
analogue Sat IF tuner  (950 to 2100MHz) are both still sitting a  box.
as is my LMX family synth (I did mount it on a DIL header and test using=20
National's PC sw and 2 x 850MHz minicircuit VCOs).

I've been distracted by other things. Also I got "present" of 18GHz plug=20
in for my previously 110MHz only HP141T (I have to pay eventually).

see www.techtir.ie

I also have a bunch of NE602s etc, some design done for Spartan 3E=20
starter kit based SDR. Need to buy better ADCs for it.
