Hi Dave and all, Even though I haven't shown up Tuesday nights, I want everyone
to know that I am on 222 and available for skeds and certainly for contests and
hopefully band openings. It's just Tuesday nights that are the problem. I don't
get home from a weekly (paying) gig until 10PM or after. As far as I know there
are no other stations on 220 in FN54 (it would be nice if I was wrong so I
could work my own grid!) and I'll sked anyone any time. I check email many
times a day so that's a good way to get me..
bill, K1DY FN54JQ Maine

Subject: [222Activity] 222 Activity Nights
It has been about a month since we started the 222 activity nights. It
is going. quite well in some areas. Not sure about other areas. It is a
big country after all! I am not a member of many VHF reflectors, so
have only been pushing the idea to The Northeast area, VHF Contesting,
and the 222 activity group. Hopefully, the word is being spread to other
areas.
In my area, there is a pretty good group of dedicated people who try to
get on each Tuesday night. Of course, life can always get in the way,
but, for the most part, a good group shows up most Tuesdays. Some calls
heard often include: WW2Y, KO4YC, VA3ELE, VE3ZV, VE3DS, WZ1V, N1SV,
K1PXE, N3RG, KA2LIM, K2AEP, and W9KXI among a few others! Quite a list
and it sure is fun seeing who you can work and say hello to.
This last Tuesday, May 25, was quite good generally, with warmer air on
average causing local signals to rise. The real long haul contacts still
can be troublesome, with little or no enhancement. I listen to the
K1IIG/B beacon and it seems to be stronger of late. Signals from 500
mile distances do not show much change however. The good news is that
500 mile contacts are being made on CW. Contacts in the range of
450-525 miles included VE3DS, VE3ZV, VA3ELE, and KO4YC.
I puttered around with my HV supply for the 222 amplifier. My step start
died due to builder error. I mistakenly used a 115 volt coil relay and
put it across 230 volts AC. I found another relay with a 115 volt coil,
but could not get it to work properly. Part of the problem was caused by
having a Variac in the primary. Once I drew out the circuit I saw my
problem, and tried to put some series resistance in the relay coil ckt
and put it across the 230 volt line. (not from one side to neutral) The
problem is that the relay draws different currents while it is trying to
pull in, and then when it is fully energized. I got it to pull in, but
then the current dropped and the voltage soared to 170 volts. This would
eventually cause another smoke event, so I abandoned that idea. My
solution was to find a 230 volt coil relay. Another solution would be a
230 to 115 volt step down xfmr. VE2XX uses varistors. That sounds good,
but my surge is especially severe, since I am using 12 X 2000MFD 550
volt electrolytic caps. Being a capacitor input supply with very high
peak currents, I wanted to keep any stray resistance away from in front
of those capacitors! It is 166 MFD! Power supply regulation under load
is a problem.
I did not get a chance to try any impossible contacts this time. The
distances between 450 and 650 miles would be fun to try. We just need
activity in the right places, and have gear that is capable of some long
haul DX. Maybe some increased activity on 222 MHz might convince some
hams to get active and / or upgrade their setups? 222 can be a
fantastic band, but I don't need to tell you all about that! CU all
next week.
