Dave,
The defensive approach drives off everyone but the true believers; only
something incredibly valuable can survive this.
Well put.

If you are using an IC7000 this is as easy as adding a filter slider control
to either HRD, DM780 or both. It's not too hard from the front panel, either.
There are also three filter presets. I'll leave one at full bandwidth and
another at the bandwidth of the mode I'm using. 50Hz is no

Testing with a monster signal nearby will be interesting. The ADC in the SDR-IQ
digitizes several MHz at a time and then does filtering. The ADC in the sound
card digitizes only a few kHz from the TS-2000 audio. You'll see which has
better dynamic range.

One other technique is to leave the rig in USB mode, crank the Hi / Shift down
to 1400 hz and tune the frequency until the interfering signal is at 1500 hz
(or use the Lo / Width if the interfering signal is on the low side). The
minimum width is about 400 hz this way, not 50 hz, but it is
Hi Andy,
Here is a MixW/TS2000 macro that will center the selected signal and
then reduce the TS2000 bandwidth to about 100 cycles (lines beginning
with a semicolon are comments and can be removed).
; move RX to 1000 (center of filter bandwidth)
ALIGN:1000
; move TX to same place

Hello, Simon.
There are many posts from Russian-speaking HAMs about incompatibility of HRD
and DM780 with Cyrillic alphabet.
The DM780 shows unreadable symbols in the receiving window in case it was
transmitted in Cyrillic,
and it's not possible to type Cyrillic in the transmitting window.
Hi Vlad,
I agree - but I really have not been able to find someone / anyone who can
tell me exactly what the character translation is so that I can do this.
Obviously I must use a Cyrillic font, but I have to map the characters I
decode.
If you can get me the table for this mapping (and not a
Folks:
I have posted another graph of error rates versus signal / noise ratio with
AWGN from PathSim. This data set uses 2300 characters (ham calls) per data
point. Using UOS gives more reproducible data. The original Baudot audio
files were produced in MMTTY.
I would be willing to share the
