[MRCA] September 23 Long Range Reconnaissance Communication Ops atMRCA Meet

[W2HX]

I should be able to confirm attendance in about a day. I am hoping to bring
my harris falcon (RF-5000) 125W mobile set up and an AS-2259 (with RF-382A
tuner) and a vertical in My FJ40 landcruiser.  Not sure where you might want
to deploy me.  I'll let you know tomorrow or so to confirm.

Dale et al:

     I'll bring my NVIS antenna array (crossed inv-v's for 80/60/40) as well

as some new (to me) HF mobile whips.  I'm not even sure on what bands these 
resonate.  A couple of years ago we used my NVIS system as the dipole set 
that we could raise and lower quickly in the field (we actually just held up

the ends.)  Let me know if you gents want to try anything with this 
equipment.

Over the years our long range reconnaissance comm event has changed. In the 
early years it was a group visit to Big Pocono State Park ( 17 road miles, 
10 air miles) to exercise various AM field sets and various antennas 
principally to get a signal report from the MRCA base station at the West 
End Fairgrounds. In the last few years we have divided our growing group 
into comm teams and added Beltzville State Park (17 road miles, 12 air 
miles), Jacobsburg State Park (17 road miles, 11 air miles) and most 
recently Minzi Lake Park (22 road miles, 12 air miles). We still have the 
opportunity to try our AM, SSB, CW and FM rigs on HF and VHF back to base, 
and, in addition, to the other team locations with various distances and 
terrain in between. In recent years we have attempted some "scientific 
inquiry" with signal comparisons with vertical and horizontal antennas and 
the use of Near Vertical Incidence Skywave propagation. Let's continue this 
experimental trend this year.




Some possible areas for a comm team experiment:

. Comparison of a stock AS-2259 antenna to one modified to amateur frequency

wire lengths

. Comparison of a stock AS-2259 antenna to a home brew AS-2259 
configuration, or a simple low dipole, or another commercial antenna.

. Repeat of an NVIS experiment from a couple years ago where signals were 
compared using a dipole whose height could be rapidly changed.

. Comparison of various mobile antennas, e.g. screwdriver, bug-catcher, 
auto-tuned whip. etc.

. Comparison of a whip antenna in vertical position to the same one tilted 
at various angles

. Compare operation of similarly configured half wave antennas, one end fed 
and the other center fed.

. Comparison of a low dipole with and without a counterpoise


I know there are MRCA Meet attendees interested in some of these 
experimental areas. Make your interest known by posting on the MRCA 
reflector. You may get some comments, ideas and volunteers. You may have all

the gear necessary for an experiment. If not, other interested comm team 
members may be able to bring an extra antenna, supports, coax, tuners and 
switches to assemble an experiment and configure it for rapid signal report 
comparisons.




The MRCA base station at the West End Fairgrounds will be equipped with a 
Stoddardt Field Strength Meter this year so that signal strength differences

can be measured fairly accurately in db.
