[Premium-Rx] RE: Premium-Rx Digest, Vol 12, Issue 8

Wed Nov 7 22:36:03 EST 2007

Hello all,

1st posting here for me.  I've been following the discussion here on "best receiver" and my addition will be I've had super success using an HP 3586 as a very accurate low noise sync detector with receivers such as the R-390A, etc.  

Also,  I am looking for a copy of a service manual for my Rycom 5307B VLF tracking receiver to check its alignment.  

Thanks,

Leland  NC9K
