I have to disagree with some of what has been said about how much power to run
using JT65.
JT65 is a LOW SIGNAL mode, NOT a LOW POWER mode.
We run 1500 watts into 20+ dB gain antennas on 2 meters for EME. Signals
coming back from the moon vary between –10 and –29 dB
Why limit yourself on 16

Hello
so how much power to use in JT65 on 160 mts for DX ?
15-25 watts in OK on high bands, but how much pwr people are using on 160
mts?
thanks,
Jorge

Hi Jorge
Hi Jorge
JT65 is no diferent from CW or SSB, more power is better...use no more
than 50% of your amplifier power, if you have an extra fan use it on
top of your amplifier..

I've used 100 watts on 160 - by accident, as I forgot to turn down the drive -
I discovered that decoding can be a real problem at high power levels. I've
seen signals from a station 30 miles (50 km) away that wouldn't decode
because of spreading. I believe the main goal is to have little or
need as much power.

It is NOT a QRP mode, it is a weak signal mode, not the same thing. On 160
often a QRO mode to give a weak signal at the other end.
I usually use 40w to an

I have worked VKs and JAs on 160 and 80 with these settings. 72/73 de Jim

I my very limited experience with digital 160, I have found that I have
to run more than the usual power for such, since I am using a very poor
inverted L antenna for transmit. That said, with 50 watts I have managed
to work 7 countries, in 2 continents. And that is with limited operating
time.
How much of this was JT9? Is it ALL JT65?

It's all JT65.
Notice all the CQs going unanswered. Except for the Ukraine station,
those EU stations all had pretty good signals at your QTH, good enough
that some of the guys in W1/W2 should have copied
Thanks, Jim. Maybe I'll stick with WSPR, at least for awhile. Per the Sept.
10 thread about VK2KRR, there seems to be some 160m activity on that mode.
I've enjoyed WSPR in the past, but the Linux version of the software I was
using at the time would crash at odd intervals. Hopefully, downloading t
I have had many across the pond WSPR reports over the years.
I'll have to give JT65 a try as well.
