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...
73,
~~Guy, W6NJX
not think we should
pursue this topic on the Flex lists.

Desense is overload (compression). You need a lot of signal to

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

Guy,
I do not think that I de-sense anyone's receive capability with my 25 watts and
indoor antennas. I typically get signal

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.

When I get a chance later today I’ll 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.

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

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

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
the signal being presented to the transmitter already has

JT65 is not PSK,and differs from it in many ways. The program is extremely
thoroughly documented and the info
