hear how to improve you chance on winning your next contest.
Take the Capital Beltway to Exit 7-A. Head south on Maryland Route 5
(Branch Avenue) toward Waldorf. Immediately after entering Branch Avenue
you will come to a stoplight, which is Manchester Drive. Turn right on
Manchester Drive. In the middle of the block on the left hand side, you

OPEN HOUSE AT WR3L SATURDAY SEPTEMBER 21st
PVRC family open house at Dave Baugher, WR3L, in Essex on Saturday,
September 21st at 12 noon until.... Looking forward to a full house. It
is an informal get together to extend the summer season; an outing much
like the fowlfest. Not sure of the menu but there will be plenty for a
good appetite. Bring a salad or desert if you wish but by no means
necessary - just come!
VIA 95 North through the tunnel and exit on the Baltimore Beltway (695)
East to ESSEX exit 64. Get in LEFT land and exit on 702 to ESSEX (Left
exit at Golden Ring). Continue through four traffic lights on 702
(Southeast Blvd) about 2 miles. After 4th light take 2nd intersection.
Turkey Point Road to the left. If 702 is not dual lane you are too far@
Continue on Turkey Point Road to the end. Turn left on Rockaway Beach
Avenue. Continue to 615 and park my parking area or on the street if
Boaters welcome. Bring bathing suits is optional. Good swimming area and
small pool weather permitting.
PVRC OVER-THE-HILL FOR AUGUST by Andy Anderson, W3XE
PVRC Over-The-Hill Gang met at the Holiday Inn, US 1 and the Beltway on
August 14th at noon. N3RR informed us about the new regulations about
power. You can't put a multi-
element beam at 6 feet and squirt 1.5 kw of RF at your neighbor. W3ABC
enlightened us about the problems on 2 meters. It was pointed out that
50% of the Hams use repeaters but yet they are supported by only 20% of
the users. HOW TRUE. K3ZO went into details about how they are cross
checking contest logs for accuracy. Surprised me. Other important
problems of the world were also solved. Attendees were: K6IR, W6QXX,
W4DM, W3TMZ, AA4XU, K3ZO, WB2BZR, N3RR, W3GN, W3XE, W3ABC, and W3CPB.
W3AZ will be the Host for the September Meeting.
MINUTES FROM FOWLFEST AT W3YOZ by Rich Boyd, KE3Q
The joint Fowlfest was held on the 17th of August. Those present were:
KE3Q, N3MIL, K1HTV, K7CMZ, WR3Z and Theresa, N3ORY and Debbie and Kristen,
W2EOS, N3QYA, G0AYN and XYL, N3JT, K3ZO and Somporn, N3FZB, K3DI, W3MR,
W3LPL and Phyllis, K4JAB and XYL, KE4PSV, WG3U and daughter, N3HSA, N1KCE,
K3CHP and XYL, WB3ANE, W3AZD, W3EKT and XYL, WB2BZR, N3RR, WR3L, WA1SPT,
WV3B, W6AXX, WB3AVN, AA3KX, AA6DC and Rebecca, KA3TGY, K4VV, K3MQH and
Mary, W3YOZ, W3HVQ and Margaret, AA4EL, N3RQV, WC4B and KB4FAS.
As usual, NCDXA met jointly with PVRC, though we each held separate,
consecutive, meetings. For the NCDXA goings-on, see the NCDXA minutes.
For more info on NCDXA, send a packet message to WV3B. Thank you for
joining us in a couple of the summer meetings, NCDXA!
The W3YOZ Fowlfest affair was FB as usual. N3RR kept us in suspense for a
while as we waited for his boat, with PVRCers aboard, to come into view.
The water was a little shallow over the bar into the creek and AA6DC and
K3MQH had to go over the side to walk the boat in, the last half mile or
so! But they did eventually arrive.
The grilled chicken and beverages were abundant as usual. Plans for the
fall contests were discussed. N3RR suggested PVRC study the near field
signal intensity health hazards issue. He was promptly appointed
committee chairman. Also on the committee, to my knowledge, so far, are
WA3WJD, W3HVQ, and W3MR, each of whom has particular interest and/or
expertise in this area.
Marty gave tours of his updated station and antennas, including his 160M
vertical-supporting balloon, its hangar, and its raised radial system.
Also interesting was his "marsh tour," the site for his planned 80 meter
four square. Marty claims 6 db signal improvement at this waterfront site
over an inland site. He says what he can hear on 160 is really amazing.
After the meeting an application for membership was accepted from WG3U, to
be acted upon in the immediate future.
NW REGIONAL MEETING MINUTES 20 AUGUST by Tyler Stewart KF3P
The meeting was called to order at 8 PM at Legends Restaurant/Hampton Inn
in Frederick, MD. Members in attendance were: KF3P, N3RR, WB2BZR, K3TZV,
W9LT, K3ZNV, WB3ECU, WD3A, W3EKT, and NE3H.
During introductions, W9LT and K3ZNV related their latest tower/antenna
projects. WB3ECU has been procrastinating on digging a base for his new
tower. WD3A relayed his dilemmas with his pop-up camper during a recent
camping trip. W3EKT bought a small mobile home. NE3H put up a ring
rotator and has been dabbling in the RTTY contests. KF3P got on for both
modes of NAQP and is starting a big push to get his next tower done for
the Fall. N3RR just got his new F12 80 meter dipole up and tuned. He
reports it is working FB!
KF3P is looking for operators for the CQWW RTTY contest to do a
Multi-multi from W3LPL. W3EKT will be out of town, so he's trying to
organize the effort this year. If successful, the station will use WF1B
combined with either a HAL PCI4000 card or K6STI's new RITTY
software/Soundblaster combination on all bands, as well as the normal CT
network for logging. If interested in operating, please contact Tyler,
KF3P ASAP, on the cluster or 301-414-5444.
NE3H noted that he and W3TZV would like to join the crew.
Upcoming events noted:
8/23-25 VHF Conference in CT
9/8 Gaithersburg Hamfest and
11:00 AM meeting
9/9 Regular PVRC meeting
9/10 South Central Area Meeting - contact W4MYA
9/14-16 ARRL September VHF Contest
9/28-29 CQWW RTTY
N3RR presented his uncut video tape of the raising of "Frank" (short for
Frankenstein, his nickname for the new F12 80 meter dipole). It was an
all-day job perform ed by a US Tower crew along with ground support from
AA3HM, WR3L, and WA3WJD. It's up and working with greatly increased
bandwidth over the old shorter one. Meeting adjourned.
The next Northwest meeting will be on September 17th (third Tuesday) at
the same location. We start gathering at 6PM for dinner and gab, with a
meeting at 8PM. For more info, contact Tyler, KF3P, on packetcluster,
firstname.lastname@example.org, or 301-414-5444.
THE PVRC EXCHANGE by Ed Steeble, K3IXD, email@example.com
Welcome to the many new members. Several have sent me packet messages
asking about purchasing a PVRC T-shirt, embroider golf shirt, name badge
and QSL cards. Unfortunately I have to order a minimum number of each item
or there is a surcharge. Therefore, I take orders for PVRC hats, T-shirts,
sweatshirts, and embroidered golf shirts once a year. Watch the January
newsletter for the order form. My objective is to have these items to you
in time for Dayton and the ensuing hamfests, gatherings.
Currently AA3HM, Craig, is taking orders for PVRC QSL cards. Look for the
order form elsewhere in the newsletter. I doubt AA3HM will do another
order before next August so stock up now. Use the PVRC cards for those
To order a PVRC name badge provide your call sign, your name as it is to
appear on the badge, and $5 (or $7 if you want it mailed to you instead of
picking it up at a club meeting). Mail a check (payable to Brian
McGinness) to WA3WJD, Brian McGinness, 4618 DeRussey Pkwy, Chevy Chase, MD
ARRL WASHINGTON OFFICE EXPANDING by Paul Rinaldo, W4RI
The ARRL Washington office has an opening for an Electronics Engineer with
spectrum management experience. Spanish language would be a plus. Send
resume to: Paul Rinaldo, W4RI, ARRL, 1233 20th St NW, Washington, DC
20036, fax 202-293-1319, email firstname.lastname@example.org. [See next article.]
BABBLINGS BY THE EDITOR, K3DI
I am essentially retired but have been helping the League's Washington
office for the past two years. I am glad the board has approved expansion
in Washington. Last week I worked four days; that is about as much I like
to work per MONTH. Paul is hard to catch so he prefers that your initial
contact be via a resume. However, feel free to contact me (see
"Newsletter Editor" on page 1) and I can give you additional information.
I expect that there will be an announcement about the position(s) in the
November issue of QST.
KE3Q has been asked several times who is the ham with the Telrex TB5EM
tribander and big 2M yagi along the Beltway at Route 50 near New
Carrollton, MD. W6AXX reports it is AB5DR, Robert Evans.
KE3Q has dropped email@example.com and will be firstname.lastname@example.org as soon as it's
activated. The old standby, email@example.com is still in operation
too, he expects to shift the bulk of the traffic over to the new Erols
In reply to a request for more info about what is happening at the PVRC
contest stations we have received the follow from Pete.
UPGRADES AT KEARNEYSVILLE by Pete Smith, N4ZR
This summer's efforts at N4ZR have focused on the low bands. I've
received the 40-meter conversion kit for my C-3, which mounts a separate
rotatable dipole for 40 on the C-3's boom, and will be installing it as
soon as I can get an antenna party together, because the C-3 must come
down for it to be installed. I'm also collecting the bits and pieces for
a "lazy-vee" array for 80, along the lines of K3LR's 160-meter array. The
modeling results look very good as far as gain, F/B and take-off angle,
but we'll see what real life brings. Who knows, I may even get a
160-meter inverted vee installed if the weather stays good long enough.
I'm also planning a beverage aimed at Europe, with switching so I can do
quick A/B comparisons with the EWE I installed last summer, and which I'm
not completely thrilled with.
IONOSPHERIC EXHIBITION AT NOAA by Frank Donovon, W3LPL
During the month of August, the Electric Space Exhibition, the first major
museum exhibit on plasma physics and its effects on life on earth, is on
display at the National Oceanic and Atmospheric Administration's Science
Learning Center, 1301 East West Highway (near the Red Line station) in
Silver Spring, MD.
HF enthusiasts and Radio Amateurs with an interest in ionospheric physics
should take advantage of this opportunity to visit this major museum
exhibit. I hope many HF enthusiasts in the Washington DC area will take
advantage of visiting this exhibit while it is here for the month of
CONVERSION OF FLUX TO SSN by Dick Wilder, K3DI
Twice this month I have seen folks on packet asking how to convert solar
flux to sunspot number for use with older propagation models. Some time
ago, I found an algorithm that agrees with a curve in the RADIO HANDBOOK
by W6SAI 23ed page 20.16. Here it is in a generic BASIC.
1 INPUT "2800 MHz Solar flux is=";SF
4 SS= (SQ-.728)/.00178

Note to readers via the PVRC/K3SA web page:
The paper version may have either/neither/both the above sunspot
table and an order form for QSL cards. I think it may have both.
I modem the final edited WP-5.1 file to N3KTV who gets labels
from WA3WJD and takes care of printing it, reproduction, and mailing.
Works great except that there is a difference in our printers and,
as yet, I have not figured just how much to send. We also have a
difference in paper weight for my draft pages then he adds the 14"
cover sheet with advertising so there is some question about weight.
This month, I asked Jim to append either/neither/both the sunspot
and QSL order form as allowed within the one ounce weight limit.
It is interesting to get my copy in the mail and see the great
job Jim has done with the finishing touches.
