[R-390] Suggested Test Equipment for R-390A Alignment ??

[Cecil Acuff]

Hi All,

        Mike is right...the 8640B does go down below 500Khz.  I was
confused...I picked up the 606A because of several radio's I have that use
50Khz IF's....not 500Khz as I stated.   I have a couple Halli's and HQ
series Hammarlunds....

All that said...the HP-606 is a good alternative for the URM/25 if one wants
something closer to Lab Grade for someone working on an R-390X series or any
of the above mentioned.  Cost is about the same...

Cecil...
