Colleagues,
I have been running JT65A using the JT65-HF software for the past month or so
with good results (several hundred contacts with at least half DX). I have a
Flex-5000 and I am running PowerSDR 2.2.3 under Windows 7/32. I have set my
Drive control to 100 and have adjusted the VAC TX
Ed,
Are you serious?
Understand that JT65 is a WEAK signal mode; one the biggest problems is
people running far too much power and causing de-sensing.
Please do a little research on this mode before proceeding; and try
running 5 Watts.
I don't mean to be snippy but...

Guy,
I do not think that I de-sense anyone's receive capability with my 25 watts and
indoor antennas. I typically get signal reports of -15 dB and I do not believe
that I have ever received one better than -09 dB. I only asked the question
because I was curious as to why I could not increase
Ed,
I run JT65 all the time with 5 watts of power.
I worked JT1 last night which was Mongolia.
Turn down your power and have fun..
The most you may need is 20-25 watts.

Desense is overload (compression). You need a lot of signal to
Ed
Have you tried to get higher power with other digital modes ?
I can get 60+ watts out on PSK with Drive at 100, ALC level of -3 with
level slider -1 .
Are you certain your xmit filter is not attenuating the output.. have you
tested with a dummy load ?

Or run higher power on 160m and open some paths not normally useable.

Dave,
Thanks for the hints.
First of all, the dummy load does not make any difference compared to the
antenna since the VSWR is essentially 1:1 with the antenna.
I did try PSK31 using DM780 and I was able to obtain about 50 watts output with
the ALC reading -3 dB...I believe that I moved the

Put the radio in DIGITAL mode, upper probably and ALC should not be a problem.
This is why we did the mode. If you are already in digital mode, let me know

If you setup a custom TX filter, mine is 1000Hz low and 1800Hz high, you will
get more power out with the VAC TX slider set a lot lower than what you are
running.
The only problem with doing it that way is you can't have TX=RX offset turned on
in JT65-HF, if a station is -400 from you then
Ron,
Thanks for the comments!
I am one of those guys who really likes the click-n-go capability of JT65A. I
have enough difficulty remembering to mouse click in the twelve (or fewer)
seconds that I have before the next minute starts. If I had to also move the
radio filter, I might have

When I get a chance later today Ill see the max power I can get out of JT65
alc -3 drive slider 100 into a dummy load.
Have you tested your max power out hitting TUN and running Drive to 100 ?
Maybe your overall output power is low.

I can get 100 watts out in the tune mode (and CW when I use that mode).

Your PA is fine.
The amount of drive is dependent on the AF gain being fed from the
digital mode program. If it is not putting out 0 dB, then a VAC TX gain
setting of 0 dB will not produce very near 100 watts PEP with a tone.
You ALWAYS want to use DIGx modes for digital mode operation

In order to keep sidebands in check and keep emissions narrow, most of the

Thanks for the info, Tim.
Maybe I am being too conservative with the -3 dB on the ALC, but I do not want
to put out some of the garbage that I sometimes see when listening to JT-65
signals. A setting on the VAC TX gain of -1 dB would not put out anything close
to 100 watts on my rigs, so
Good info, Brian...thanks!

Using a transmit profile with a 250Hz wide filter centered at 1500 will help .

Well, actually, it won't. The only reason to run a narrower TX filter is if

I'd like a finer control over output power in PowerSDR. With my Flex-3000 in
the digital modes the power control isn't fine enough. Id like to see the
ability to adjust in .2 of a watt increments at times. Right now this just
isn't possible.

Maybe I'm wrong, but most of the controls (including, I think the Drive
slider) move in 1 dB increments. In a Lab environment, +/- 1 dB in the
RF domain is a tough target to maintain without a LOT of process.

OK in a conventional radio you adjust the audio level to adjust output
power. In PowerSDR you have to adjust both the Drive and (VAC) TX gain.
Doing so I can't get exactly 5 watts output I desire on my digital watt
meter it's always several tenths off. I know that the meters accuracy may be
