We ran both phone and CW, both with amps (~1 kw) simultaneously on 160m
during the RAC contests. Also did that on all the other bands too. SSB was
1845 and CW was 1825 (we never op on a multiple of a 10 khz MW IMD
product). Separation was perhaps a wavelength. No special filters or
anything were
A used Tek 1502 TDR is the "gold standard" to me anyway and they can be
quite cheap at flea markets etc. They are "arm held" and self contained
portable so ideal for up to 1000' runs and have enough resolution that you
can "see" defects that you don't really need to worry about. The advantage

Even better is to use S Meter dropdown in the KIWI extensions menu it
gives a strip chart style presentation that can be configured to easily
show small differences in signal levels, far easier to watch and more
accurate than the S meter display.

This should be a good candidate for the KIWI network of SDR's and their
TDOA transmitter locating ability...

Try to find/borrow a older Tek 1502 TDR, they are inexpensive on ebay
(~$100) and show way more detail than any of the analyzers I've tried.

Steve, I was hearing some audio on a few on the Eu MW channels around 0040
ut and then saw the spot for FR4NT and checked, and was hearing bits of
signal. Perhaps peaking around 0100. As usual the peak seemed to come

Hi Steve;
Even though I am about 80km from the nearest MW transmitter, BCB IM is a
constant issue here. Considerably worse in the winter. I am always VERY
suspicious that any crankup towers would be a significant contributor to
the creation of IMD products, both because of the sliding sections a
Well I disagree that gain isn't important. Maybe you topbanders in the
better areas of propagation can afford to throw away many db to get a
better rdf, but that sure isn't the case up here in mid-northern VE6 land.
I have numerous receive antennas including many beverages and Wellbrook
loops (lar
It is unusual for AM BCB signals on a 10 khz raster to produce signals
every 5 khz.
It is relatively simple to insert a MW rejection filter in a RX ant loop
which should alleviate or cure the problem without having it affect 160m
signals. For example:

Similar observations here Paul in my never ending battle to keep on top of
the noise situation in my rural area - mainly 14.4 kv distribution and
some 25kv 3 phase stuff.
Many sources top out above 135 mhz but well below 450 so a yagi in between
is certainly helpful. Like a ch 13 tv yagi or som
