Don,
I believe it!
The R-4C full Sherwood is not a Ten-Tec Orion II..BUT in most crowded
band situations it will hear as well!
Of course it lacks a lot od bells/whisles...but for pure copy it is
tough to beat even in 2011.
Rob Sherwood is genious and His guy did my R-4C at Rob's shop before

That video is now on DVD, so much handier, and is done by Hi-Res. Also
available from Electric Radio's store and is the same price. They do a LOT
of Collins and receiver videos.

Hi Curt,
I was thinking of buying one of those at one time. While collecting
info, I found that one of the R390A gurus had made a couple of videos
about the dissassembly, care and feeding of the beasts. These were like
8 or 12 hours of video so probably very detailed. They are for sale

There are two Drake supplied filters available for the R-4C, a 4 kHz and
a 6 kHz. Note they have a different center frequency than the other IF
filters in the R-4C. They sell for around $70-100, with the 6 kHz being
a little more expensive than the 4 kHz.

DITTO!! I could not agree more with this piece of advice. With a tight front
end and IF strip I have found the need for a noise blanker to be nil when
using the 600Hz roofing filter's and the 500 or 250 Hz drake cw filters. For
SSB BW's the need for a noise blanker is nice at times and I do open my
Hi Kevin,
I have an R-4C and a TR-7. The R-4C just has a resistor in the AM slot.
Whereas the TR-7 has an actual 6KHZ filter in it's AM slot.
I have to admit the AM does sound better with the filter (less noise,
all signal).
There is a company named INRAD (nice folks) that will sell you a 6KHZ

Hi All,
I am thinking I might like to narrow the AM bandwidth just a little in my
R4C. I am thinking of a 6 kHz filter. Can any of you tell me what is
available out there in that bandwidth and what you think the approximate
cost might be?
Thanks much and very 73.
Kevin :)
Amateur Radio:
All R-390As are excellent with the Collins versions being the "gold
standard." Here is what I recommend:
1. A complete copy of the original MIL manual.
2. Spare ballast tubes (or a suitable substitute) if you plan to use it a
lot.
3. A light touch on the slugs if you plan to do an alignm
