I used my own magnetometer hooked up to a laptop and got actual magnetic
field numbers as they occurred. You can make one for about $100. I do not
have it running now, but plan to re install it in the Spring as soon as the
ground thaws out. I buried mine in the garden to keep the temperature
I am pretty new to 160 meters, but just got done with a diversity experiment
with FT5ZM last night. My results go along with W8JI’s comments. I heard them
on 1.8265 at 2215 UT, and then tried to configure my receiver to utilize space
diversity, putting my 90 ft vertical in the left ear, and a
Hello Mike
I have found that JT65 provides a bit better than 10 dB more than a good cw
weak signal (read that as a real weak cw ) contact. I can copy signals by
ear that are listed as about -18 dB or more below the noise in JT-65, and
the rock bottom detection level for JT65 is about -28 or
I have used Andrew FSJ4 cables for years as rotor loops. Andrew does not
recommend it outdoors, but I have come up with a good technique for its use.
When you put the connectors on each end, be sure to remove about 1/2” or more
of the outer plastic sheath behind the connector body so the copper
I live in Southern ME, next to the NH border and 30 miles inland. I listened
on 1.915 MHz at 1815 Z today, (Tuesday) and could hear it quite well at about
S5 with my NE beverage. When I changed to my vertical to receive, I could
barely detect it in the noise. My beverage is aimed at 45 degrees
Hello Gary
I got to listen first time for EP6T on 160 early Monday evening Jan 19. It was
just before their sunrise. I could hardly hear them, but at times they would
peak up to about 539, so a QSO was possible. They definitely peaked at sunrise.
They were not hearing any northeast USA stations
Thanks to all who responded with all sorts of great hints and ideas for
combating the rodent problem with beverage feedlines. I ended up going with
buying 1000 ft of 1/2" PVC conduit and will lay that on the ground through the
woods. I ordered a new 1000 ft roll of RG-6 flooded cable to use
I was transmitting on 160 last week, and after calling a CQ I noted that the
background noise from one of my beverages dropped to almost nothing. Something
obviously broke right then. All checks pointed to something external to the
shack. I finally got out in the woods and checked the antenna
in the conduit for a second run of cable.

I am somewhat new to 160 meters. I converted an old VHF tower at my house to
a 160 M 1/4 wave radiator in late 2013 and have been active since then on a
casual basis. Recently I started showing symptoms of the 160 Disease, and
have been looking for ways to improve things. The XYL has nixed
Hi Mike
You need a signal generator and a crystal detector to sniff in that amp.
Feed a low level signal in with the filaments on but HV off and see how much
RF leaks thru to the output connector, then mess around with neutralization
schemes until the RF drops way down. I do that all the
Hello Les,
I worked A35T on Tuesday morning after VY2ZM, then K8PO, then K1CP. I live
in Maine, as do K8PO, K1UO, and K1CP, who are all in a line northeast of me.
K1UO was listening and heard them FB and did not call, but the peak was
rolling across the state so that when they were working
