[Hallicrafters] Re: RF alignment, SX-62 rcvr.

[Art Lebermann]

Has anyone experienced this problem with a SX-62?  Low end of Band 5 is 
dead, from 28 Mhz to about 38 Mhz.  All of Band 6 works OK.  Does the 
local oscillator operate below the received frequency on Bands 5 and 6?  
I.F. is 10.7 Mhz on these two bands.  I should also mention that the 
previous owner replaced several capacitors before he sold the receiver 
to me.
