How about a simple hi-pass filter between the
rig and the antenna.? Simple cheap and effective.? Maybe like the
one attached.?

please post a link or other info with a schematic of that adapter
board - we have enough experienced eyes to examine (me I would
compare it to other circuits to see if a critical part may be
missing.? the ubitx intentionally does not have a lot of gain
until the audio amplifier.? I still suggest confirming all the
wiring at the volume control (as the designer suggests) to make
sure nothing is astray here.?
do examine how close these broadcast stations might be - I was
even surprised when the other op mentioned aroud 5 miles (12 or so
km) - I do remember building a simple direct conversion receiver
(and not very good construction) - I could get 40m CW, 40m AM
(from a different frequency) and medium wave all at the same
time.? lesson learned - building a radio takes patience - I hope
each of you find the issues to enjoy this nice transceiver!? last
night I did SSB from eastern USA to Canary Islands on 40m with it
- with scarce ions.?
