Hi,
Apparently Dentron never got that radio into full production. I have only ever seen mine for 80 meters and another I exchanged info with another ham. His was for 20 meters. We had the same 5 MHz VFO and 9 MHz xtal filter. I will finish building a radio on it.

with no filter (some yes, some no plenty of hoods off photos on the

of drive. .. and the FCC does nix even though they are factory built
amps and should have compliance tests before entry.

Re: [BITX20] Compliance Summary - other radios
Hi,
I have some other solid state gear and the filtering is more
serious. My
latest purchase (used) is a Hendricks PFR-3 and with only three
bands it
contains as many of those funny little donuts than the uBitx. They are
also well placed. My old Atlas has a complete set of low pass
filters on
the output AND the interstage filters. It resembles a box of donuts
from
a real donut shop. I have a Ten Tec receiver that covers from 300
kHz to
30 MHz and has seven switched filters in just the front end and some
more in the synthesizer section.
I also have a Dentron 80 meter rig rated for 12 watts with
absolutely no
filter after the final!! I have it sitting on the shelf just because I
cared to remove the cover and look. No filter shows up on the
schematic.
Can't be. But it is. Now that uBitx has my attention I will probably
roll a set of filters for that Dentron too.
UBitx is fixable.
