[Premium-Rx] receivers with 20Mhz IF?

[Keith Densmore]

A Racal RA6790/GM might help you here. It has a broadband input but the IF is around 40.455  MHZ if my memory is ok. Use something like a NE602 as a conversion osc/mixer to drive your SDU.

  Ok, here's one I know you will all laugh at me on.  I came across an old HP spectrum analyzer, specifically, 851B display and an 8551B RF section. For those of you fortunate to have never seen one, here's a picture. http://www.fairradio.com/hp-851b.html

  It weighs about as much as my 1961 MGA.  So I started thinking about what I could use this for. Asking around on the HP/Agilent list, I found out that the 851B Display takes an IF input of 20Mhz.  Asking around further I discovered that I could not easily locate a more modern RF section (at say 1/10 the size) because the 20Mhz IF was abandoned by HP.

  So I got ta thinkin.  Are there any receivers that use 20Mhz as IF output? I thought the display section alone could make for a neat panadapter/sdu.

  (Ok, you can stop laughing now!)
  Eugene
