I forgot about my log splitter. That is #10.   I'll stick to snow shoes!

    Hi VHFers

    Last night was quite an adventure.  With a VHF shack that is way out
    behind the house, access can be difficult in winter.  With about 2
    ft of
    snow, my only way to get on for the activity night was via snow
    shoes.
    Fred, N1DPM suggested a snowmobile. I have so many small engines here
    that I cringe to have any more as they are a huge amount of work with
    maintenance, storage, and all that goes with it.  Too bad my neighbor
    doesn't have one and likes ham radio! (see below)

    I was working on all my 160 meter Beverage wires while we had some
    snow
    free days, and I made the best of it. We got a big dump of snow
    towards
    the end of that project, and I ended my Beverage repairs by using the
    snow shoes. While I was traversing the property, I decided to break a
    trail up the hill toward the ham shack. I broke a trail about
    2/3rds of
    the way up there. I stopped when I gained the ridgetop and the
    remainder
    of the trail was only a slight upward walk.  In hindsight, I
    should have
    gone to the top as the snow developed a pretty good crust which made
    snow shoeing pretty hard. If you have not done any snow shoeing, just
    imagine your big web feet breaking through a hard crust, and then
    try to
    lift your feet up and have those big web feet get caught on the crust
    and you have to lift that crust along with your feet! It is
    difficult.
    Last night I broke the remainder of the trail and it took a long
    time. I
    left the house cat 6:15 PM and made my first contact 47 minutes later.

    It was quite beautiful trudging through the woods with all the
    snow, but
    then I had to dig out the two doors of the shack. There was a lot of
    snow all drifted up! I keep a snow shovel up there just for that
    reason.  I stowed the snow shoes and entered the building and
    turned on
    the genset, 30 seconds later I saw the voltmeter come off the
    bottom peg
    and go up to 120 volts.  (Yay!) The 30 second delay is due to glow
    plugs
    heating the cylinders for awhile so the fuel will ignite in cold
    weather.  My old military 30 KW diesel did not have glow plugs. That
    beast had a metal bottle of ether, and you yanked a lever and sent
    pure
    ether into the cylinders to aid starting in cold weather. Kaboom!
    Since my generator repairs, the diesel has been working great!  I
    have
    its 12 volt battery on a tiny solar panel and charge controller, 
    and it
    keeps the battery healthy in winter.

    Here is my log. Conditions were OK. I cannot complain when I have two
    contacts over 500 miles in January!

    Number of QSO listed: 18


    My try with Howard, WA3EOQ was rather difficult. There was fairly
    rapid
    QSB where he disappeared into the noise. I only copied him on
    peaks. It
    took about 5 minutes to complete. Howard mentioned that I was pretty
    solid there, but I had a 12 dB power advantage. Howard runs 100 watts
    output. The only way I worked Howard was due to the low noise
    efforts on
    my system here. My first try with no tower mtd preamp was not good
    enough for EME. Yes, I made contacts, but I could tell that the other
    station always heard me better than I heard them. Upgrade #2 was a
    tower
    mtd preamp, but I was always plagued by RFI from a CH 11 digital TV
    station at a 219 degree heading. Other directions well away from 219
    degrees worked fine, but 219 degrees is the main heading for all
    the VHF
    activity. What made the situation difficult was that the overload
    artifacts from CH 11 did not sound like RFI. The only evidence was a
    slight increase of the noise floor. It sounded like natural random
    noise. Many attempts at high dynamic range preamps could not
    eliminate
    the problem. I tried a LNA Technology cavity preamp and it did not
    fix
    the degradation.  When confronted by this, Who ya gonna call? Not the
    Ghostbusters, but WD5AGO!!!  He made up a silver plated cavity
    thatuses
    a TX FET as the active device with the silver plated cavity to reject
    the CH11 signal.   After fitting that preamp in a larger box up on
    the
    tower, I was finally getting down to the nitty gritty and that
    made it
    possible to contact Howard and others down that way.  I mention
    all of
    this to relay the fact that such RFI is everywhere and it may be
    harming
    your frontend.  Remember that the TV signal will have peaks that
    are 10
    dB above what you will see on a spectrum analyzer. TV frontend
    overload
    is everywhere.  On 432, I was getting hammered by a CH14 TV
    station in
    Portland Maine off the back of my 432 antenna. The tower is about 45
    miles away. I had to install a large copper HB cavity up on the
    tower to
    get rid of that problem.

    KO4YC was a difficult contact as well. Cornell was using SSB and was
    very weak. I was calling on CW in a narrow passband and heard what
    sounded like weak SSB so I kept going between CW and SSB trying to
    figure out what was happening.  Finally we connected up with the
    right
    passband and completed. Signals were very weak.  I tried with
    K8TQK with
    little success. A few meteor pings were heard each way. That is a
    long
    haul over 700 miles.

    The shack was not as cold as I figured. It was 30F when I started and
    soon it was rather comfortable. Still, I had the long trek back
    home on
    snow shoes, so I quit early at about 8:30 so I could make it back
    home
    at a reasonable time. It took about a half hour to get back home.
    I was
    very [leased that I could participate in the 222 MHz Activity
    period and
    would like to thank all who made an effort to get on and make noise.
    AJ6T had an iced up antenna and apologized for not being able to
    transmit! NiGC, AA9MY, K8TQK, W5EME, and K9MRI were all in there
    making
    contacts.  In the NE, semi newcomers like WA1MBA, KA3FQS, N1FSY,
    WA1RKS,
    and K1FSY are adding to activity and it shows.  It bodes well for an
    upward climb in 222 MHz activity coming in the future. Thanks to all.
