[TenTec] Orion 565 Sub-Rcvr. Problem - Squealing Tone, no signal

[Steven Kline <skline4@verizon.net>]

Has anyone experienced squealing tone in sub-receiver (not 366 type) which 
varies as you rotate vfo.  Radio was re-capped and new battery.  Have performed 
ram clear and master reset consecutively several times.  When squealing tone 
occurs I can turn sub-vfo couple kHz and goes away … then just dead air no 
signal…. go another 5Khz or so and here comes squealing tone again.  It’s seems 
to be cyclical.  I’m not getting any discernible signals since this started 
last night.

Anyone have thoughts?

Thanks,
Steve - W5JK
