Jorge,
I use only 35-50w on TB. A few years ago I worked VKs and Zls using only
35watts then went down the band a bit and worked one of the same stations on CW
only moments later BUT it took over 900w to do it. That is just over 14db
advantage over CW. Two other things to remember 1. JT65 is
I keep reading about all the WSPR and other low power modes where one person
was heard all around the world. Well, maybe on a given night that can happen.
-23 on JT65 is 10 dB below the threshold where a CW signal can be copied by
ear... and I see many signals on JT65/JT9 at that level into m

Do you guys use lousy receivers for these modes? Why would the mode affect the
abilities of a receiver?

"Overloading everyone's RX front end" is not correct.
The problem is that these narrow digital modes are received using the full
bandwith of the SSB filter.

If I find someone on 160 in zone 23 that uses JT65/9 can someone give me a
reason we should not use 1000 watts?

The QRP guys will be miffed.

Hi all,
One of the locals here is very into the JT -modes, almost exclusively
on topband. He uses 100W into a single Inv-L with two 1/4-wave radials
and nothing for RX. I think he's about halfway to 160 DXCC in a
calendar year and reports working everything he hears barefoot -- but
again, no RX an
I too am using something similar, if not less effective, a Butternut HF 2v
with a homebrew TBR160 coil installed on a pushup mast 25 feet from terrace
(2nd floor) level, with 2 radials for 80 and 40m squeezed into my tiny 1400
sq feet terrace perimeter sloping around. Max power I have is 100W. I h
