[VHFcontesting] 222 MHz Activity Night

[Bill Olson]

woo hoo! Due to some unforseen circumstances, my music gig has been cancelled tonight.. SO... instead of making lots of money I'll be able to get on the radio and talk to a bunch of old geezers!! Yay.. I'll be there at 7 and as long as it seems interesting.. Running 350 watts to a 15-1/2 el K1FO at 120 feet SSB/CW preferred other modes "if I have to"..

Subject: [VHFcontesting] 222 MHz Activity Night

Hello 222 fanatics!

Today is Tuesday and I am getting geared up for the activity night. Last
week was a comedy of errors on my part. I am finding that I am losing
most of my fast ball and most problems are self inflicted. My amplifier
would not tune properly and I thought that my tower mtd preamp was blown
out. I also had no internet connection.  First we fixed the 5 GHz link
and got the path working again. I suspect RF on 160 meters is tripping
the link up as the dish and CAT V shielded cable is very close to the
160 radiator. We had to reset everything and re assign the proper path
names etc.   The amplifier needed some work and I dragged it down to the
shop and re worked the plate tuning caacitor system.  It had a bristol
wrench set screw that defied finding a proper tool to loosen. I tried
everything I had to no avail. I ended up machining some new parts and
used set screws that normal folks can deal with. I modified things to
allow a wider tuning range. I hope it works. My PRM-10 GDO says that it
works.

The tower mounted preamp was another hassle, and I climbed the tower and
opened the wx proof box then clipped out the preamp and took it doen to
the shop. I magine my surprise when I fired it up and saw 20 dB gain and
a 0.4 db noise figure. (?)  I also checked the SAW fiter and it checked
just fine too. To my chagrin, I found that the preamp cable in the shack
had fallen off the 7/8" cable. What a dumb move!! Now I have to climb
back up and re install the preamp at 105 ft up!  I keep saying that I
need a chaperone to watch me all the time.

So if you have any 222 MHz gear, now is the time to try it out on 222
this evening.  Most folks get on around 7 PM EDST or 2300UT. Most
activity is on CW, SSB and FT8  and use of chat pages is encouraged.
Most folks in the NE use the ON4KST page, but do whatever works in your
area.  We are trying to build activity in the entire country and that
will allow attempted skeds with stations outside of your typical
operating area. This is obviously a great way  to find elevated band
conditions. Here in the NE, we have terrible conditions this time of
year, but the Gulf states are starting to heat up and soon, with warmer
wx and a bit of humidity in the air masses, we should start enjoying
some long haul contacts here in the northeast. These great contacts are
only possible if we all make an effort to be on the band.  Tuesday
nights are a good way to ensure that your setup is working at 100%. If
the band opens on another day, you are sure that your system will be ready!!

I dragged my computer up to the VHF shack and got it all hooked up and
going. I have it interfaced with my 222 rig and am ready for FSK441,
MSK144,  FT8, and JT65.  I am now off to re install the KW amp and try
to put the preamp back on the tower! I hope it all works!!  CU this evening.
