INSTRUCITONS FOR AIDC 3733 MODIFICATIONS



>From K5GNA:

I have compiled a written set of instructions, with photos, for modifying the 
TSI AIDC 3733 & 3033 downconverters.  The modifications are simple enough for 
most people and have detailed photographs with text for each step.  The 
modifications will give you a true 1.4 dB of SSB noise figure and a narrow 
passband of 2400 to 2480 MHZ.  The image and LO are over 35 dB down, plus the 
front end is still protected by the original combline filter.

The Microsoft Word (97) document (with links) is:

The network analyzer photos were done with a handheld camera and are a bit 
blurry, they will be replaced with some improved displays soon.  Any 
information will be updated as we get new data.

TNX & 73,
