H, I have found 160-80 the best ground wave communications at night,
for even short distances. You are correct in that the higher bands are
useless for most short range stuff. I used to live 20 miles north of
Athens, and it took me months to get even one contact on 15 or 10 with the
city.
Hi Andy,
I use 80m for a regular phone SSB sked with a ham 190 miles away. 80m is
quite reliable at night apart from static crashes and a generally high noise
level. We had a recent night where phone QSOs were just about impossible
with high QRN so we did some RTTY tests. I transmitted at

I will venture a guess you are using a trial version of the software
because that is what I am hearing the voice say in the file you posted.

Hi Chuck,
The attachment worked ok here for me. The sound seems to be saying 'trial'
in a female voice. It sounds like a piece of applications software or your
driver is doing this. Have you tried killing off processes using task
manager to see if you can isolate what is causing it?

Thats interesting. I tried several earlier trial versions and all of them
worked full bore for 2 weeks. After that, if you tried to use them, you got a
pop-up that made you wait for a timer to reset before you could do anything
more. They still worked if you didnt click on a spot, but that

For this distance you can use 80 meters day and night, and 30m during daylight.
I use 10 Watts and a 4x40m horizontal loop from home, and a 7.5 m linear
loaded bended vertical on the camper. This works24/24 for distances from
20-100 miles. During night hours I use the pskmail server in

Andy,
NVIS simplified means a very high angle antenna and operating below the
critical frequency.
At mid latitudes it may mean 80 meters and lower frequencies. At my
latitude (23 N) sometimes
40 meters qualifies.
Of course, tricks may be done to enhance skywards radiation, like using
wires
160, 80, 40 meters with almost any kind of wire/dipole antenna. We
have a weekly regional net in the Sierra foothills in California on 80
meters, and never fail to copy everyone on the net.

I just downloaded a trial of MixW and there was nothing disturbing the
audio. I do NOT think it is because of MixW being a trial version.

I've spent most of my ham career on or near 80 meters. The question
depends on what part of the sunspot cycle you're in.
If sunspots are at max, 40 meters is generally solid during the daytime
hours for those distances. At nighttime, 40 meters gets long and you
will need to shift to 80/75
Follow-up -- forgot 160m antennas. While a full-sized dipole or inverted
vee is nice for NVIS, there are options for smaller lots.
A full-size dipole is in the ballpark of 250 feet total length, but a
full-size full-wave loop is only 60 feet or so on a side. Feed it

Paul,
A full sized 160 loop is not easy to set up since it needs to be around
500+ feet in circumference (1005 / 1.9 = 528 feet). This would make a
square about 130 feet on a side.
After comparing a nearly full size, low height (30 foot apex) 160 meter

Yep. I was thinking of the 80 meter one. At 130 feet or so per side,
it's pretty big, but
Andy- My recommendation would be 6M. We have a local net thatcovers a
radius of over 50 miles, at night. Sometimes MUCH more. The antenna I
find most effective is a Yagi with a low F/B (Normally considered to
be a lousy antenna) I point toward the center of the net area, and
only move if
