[Premium-Rx] TenTec RX-340

[Heinz Breuer]

Hello,
I have a problem with my TenTec RX-340 which I got from a 3rd hand owner.
Immediately after 'power on' it is totaly deaf. Within the next 10 
minutes it slowy gets better, but sensitivity is still about 40dB down 
compared to my Telefunken E1800/3. Deutsche Welle on 6,075kHz is at 
about -80dBm while the E1800/3 has it at -40dBm using the same antenna. 
I have to get my HP8640B out of storage to further investigate this.

I executed the BITE tests with following results:
BITE 1 FAIL
BITE 2 FAIL S/A: MIXER1
BITE 3 RESULT: 000:004

With my limited knowledge it appears that the mixer1 board is
defective. It seems somebody already changed the 2SC1971 transistor.

I contacted TenTec service department a week ago via eMail but no 
response. I even sent a fax on late Thursday night, no reply so far.
This is not what I am used to. My former experience with TenTec service 
was very good. I have an OMNI VI plus and had a few questions which were 
answered within hours, but this was 12 or 13 years ago.

I would appreciate any comment regarding the cause for the failure of 
the RX-340 or about the ususal TenTec service department response time.
