I noticed a small typo in the INSTALL file (wsjt-x 2.2.2 release).
In the section that describes the prerequisite tools for building from
the source code, I suspect the package "libqt5libserialport5-dev" should
read "libqt5serialport5-dev". (The later is a package in Debian Stretch,
the former is
The 1500Hz setting is in the paper.We've been very successful in cleaning up
the bands as that paper has been passed around to many clubs.

Johannes,
please do not obfuscate this issue. Increasing audio drive into the
rig's modulator, to attempt to compensate for attenuation further down
stream by the SSB Tx filter, is highly likely to overload of the
modulator, and cause the nasty audio harmonics to be transmitted, that

Bill, Ok on that. You will remember I tested the FTDX101 SUB operation
for split > rig in recent wsjtx fix. I always use that re rig split.
I see it (SUB), drop 500KHz, 1000KHz etc as I move the TX down the pan,
to keep audio frequency up in the best range.
I agree on the factors you mention,
working in a HamRadio repair shop, we had all kind of sources for
distortion,
but as long as you obey the limit on the ALC meter and do not go beyond,
there
is no distortion - not with any rig.
ALC has a delay, until it acts and swings to the shown meter info. In SSB
output power will be reduced b
Hi Adrian,
the ALC indication on your rig is usually a combination of multiple
inputs. Audio drive to the rig is just one of those, other things that
impact it may include:
* VSWR
* POWER/DRIVE level settings on the rig
* PSU voltage
* PA temperature
Also and usually critical with narrow
Bill, No not at all, I am well aware it is a TX function for adjust
during TX.
When I change bands the alc level changes , and I adjust the TX PWR to
it set where I want it, which is always the same point.
I don't always have to adjust it depending on the band chosen, but most
times on band
Hi Adrian,
if your power level is not being restored per band then something is
wrong. The last used Pwr" slider setting while transmitting is recalled
when you return to that band. Perhaps you are attempting to set the
slider level while receiving, that will not work.

Mike,
a statement like "Zero ALC pretty much guarantees you won't be
generating harmonics. Most rigs can do very close to full power without
showing ALC." is incorrect and very poor advice without some
qualification. For example setting a Tx audio offset of 200 Hz, without
using one of the WS
I already have that checkbox checked. However I still have to adjust on
band change.
It is not effective for me. If in audio setting there was a band list
with associated numeral
For TX PWR level, I could insert manually, that would be good, and I am
sure that would work.

Hi, a friend of mine uses the Perseus-Receiver with a ALA- 1530 magnetic loop.
He wrote me, WSJT-X gives error-messages - rig failure….
Can someone help, with settings? Perseus receiver uses a VAC, which sets a

Is it possible to activate CAT to Perseus?
Thank you for help.
