arghgh rew WBand SSB that might be one of those MPa'70 home built? amps as in 20 dollars on ebay and no filter set? or perhaps an RM Italia amp with no filter (some yes,? some no plenty of hoods off photos on the internet to show the awful truth)? ?and run right at the stops in terms 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.
