Hi Ernest,
I have not contributed to the software effort of WSJTX other than to
provide a bit of feedback to K1JT. I am a user of the program and
upgrade whenever a new version is available. All praise for the program
goes to K1JT, the team of software contributors and beta testers.
I am copying the list for the benefit of others.
I am running the software with a Flex-5000A. I have RX2 installed in my
Flex-5000 but that should not matter as I am only using the primary
receiver with WSJTX V1.1 in the below example.
I have had successful QSOs on JT9 with the new software. A couple of
things I do that may make a difference before starting WSJTX are listed
below.
Make sure your defaults under the Windows Control/Sound setup are 48000
for any of the VAC channels you are using. The V1.1 users manual
mentions this also.
I always made sure my PowerSDR Setup/Audio Sample rate is 48000 when
running the program. I have my buffer size at 2048. Be sure to change
the sample rate while PowerSDR is in STOP mode.
I use the PowerSDR VACs set to Windows WDM-KS with buffer = 2048 and
Sample Rate = 48000.
Sometimes when I push the START button after a sample rate change, the
Panadapter will show no activity and I will have to Stop and Start again
using the button. This has nothing to do with WSJTX.
I set VFO A to the desired base frequency. I set my receive bandwidth
from 200 to 5200 Hz..
I have setup a TX Profile called JT65&JT9. I have the filter set for 500
Low and High set to 2500. I have the extra 500 Hz to make sure no roll
off occurs at the edges. In particular, WSJTX will transmit using a base
audio frequency of 2000 Hz and JT65 is about 200 Hz wide. There is no
reason to set wider as WSJTX only transmits audio from 1000 to 2000 Hz
using the base audio frequency. It does this by using SPLIT and
transmitting with VFO B and changing the VFO B frequency as required.
This profile does not have DX or CPDR enabled. No EQ of any kind should
be required. With VAC use the TX should be flat. I select this profile.
I select DIGU mode.
I always copy VFO A to VFO B after setting the parameters for VFO A. I
do this before starting WSJTX. I then select SPLT and the VFO B TX
buttons. I have seen instances where the mode for VFO B is different
from VFO A and in fact you can do this on purpose. Check the mode
buttons while you are transmitting with VFO B to confirm they are as
expected. That is one reason I do the copy.
I select split mode with the PowerSDR SPLT button.
Although not required, I run DXLab Suite software. WSJTX supports the
Commander rig control module. I start DXLab if not already started.
I start WSJTX.
The current JTALERT does not properly support V1.1 of WSJTX. A new
version is in the works. I would normal start JTALERT here. JTALERT is a
very nice add on and interfaces WSJTX to DXLab DXkeeper log module.
JTALERT uses the log module for previous QSOs checking and logging.
I operate WSJTX as described in the V1.1 manual.
Let me know how it goes.

Bill,
It appears that the transmit portion of JT9 is having an issue.
JT65 is working okay. No issues with that software.
I am using a Flex 5000A and on JT9 transmit, no one hears me.
I conducted a test late last night and the receive portion is doing
well. However, I am not being heard. I tried reversing the DIGIU
and DIGIL (upper SSB and lower SSB) with negative report.
It was reported by several stations that they could see my tones but
no decode. They tried on their end to switch mode etc... and no copy.
Early this morning I was still testing and a KL7J called and told me
he was seeing my transmit signals on JT9 with no problem, but no one
else was able to confirm seeing what I was transmitting.
We were using K3UK O'Brien's LoTW forum to exchange information ...
through the website.
We had stations from 9V1, KL7, N4BAF, KF2T, JA's and several VK5's
etc... reporting no signals being copied.
I changed the bandwidth and try setting the EQ to pass 6KHz: Just in
case that was the issue.
KF2T found that in his setup for Dual mode the tones were reverse and
I believe he will be sending you a note regarding it. He is using a
F1.5K.
If I can be of any assistance, I am available to help with the issue.
73, Ernest W4EG
