2009 Picnic

RSS
The Big Top was set up on Friday. At least it looks like most of the rain is gone by noon Friday.

Friday Setup

Ah, only .75" of rain Friday night, so things were a bit damp in the morning. But the sun came out and it was the perfect day for a picnic.

The Harrington's Restaurant catering crew set up in the shady spot next to the shed with their portable grill, keg and other food.

I will try to get calls for as many as I can recognize quickly in the first pass, but I am doing this early Sunday morning and my eyes are still a bit blurred. If you want to help fill in please send me notes for the rest of them.

The Mystery Load Game... See if you can figure out what is on the 5 ports of the switch.

Given the Time Domain Reflectometer and MFJ-269 meter figure out what is connected to each of the 5 ports of the RCS-8V relay box on the other end of the cable. DO NOT change settings on the TDR, it should be set to adequate resolution to determine the loads.

More info:
  • There is about 20’ of RG-8x from the connector to the relay box. Velocity factor of RG-8x is about .78.
  • All coax connected to the relay box is RG-8x.
  • Each control wire going to the relay box powers only one relay.
  • The relay box has been modified with a single jumper addition.
  • You are allowed to examine the back of the control box but not the relay box. (the back has a diode from terminal 4 to 2)
  • The inside of the control box has not been modified.
  • Some useful (maybe) formulas and constants:
  • Resonant frequency(Hz) = 1/(2*π*√(L*C))
  • c = frequency*wavelength ≈ 300,000,000 m/s
  • V=I*Z
  • Z0=√(L/C)
  • E=mc2
  • RC Time constant = R*C
  • Rho = (ZL-Z0)/(ZL+Z0)
  • |rho| = (SWR-1)/(SWR+1)
  • SWR = Vmax/Vmin = (1+|rho|)/(1-|rho|)
  • 3 RC Time constants ≈ .95

Winners of the games:

  • Fast QSO Race = K2XA (4 min 49 sec)
  • Knot Tying Race = N1FJ (1 min 23 sec)
  • Mystery Loads = KK1L
  • Scavenger Hunt = AC2AC
  • Guess the Number of nuts and bolts = KA1HSP

In addition W1TO got a copy of the 2007 CQWW RTTY Plaque for his wall. And NJ1F got his 75th Sweepstakes coffee mug.

The Scavenger hunt answers:
  • 1 = The flag was on the Ground Rod - 5pts
  • 2 = The tower sections were 10' (9' 9" was acceptable) = 2pts, 10'+8' top = 5 pts
  • 3 = There were blue Pulleys = 4pts, Pulleys plus shackels = 5pts
  • 4 = Under the can is a dummy load = 3pts, stating it was 50ohm or adding other detail=5pts
  • 5 = the wire is a radial = 5pts
  • 6 = the Beverage box is from DX Engineering = 5pts
  • 7 = The rope holds the end of an antenna = 2pts, a 160m inverted V =5pts
  • 8 = the top antenna is a vertical = 2pts, VHF vertical 3pts, VHF/UHF vertical = 4pts, Diamond VHF/UHF = 5pts.
  • 9 = hardline = 3 pts, Andrew LDF 4-50 = 5pts (the name and size was on the back of the cable right by the flag)
  • 10 = The radio is from Kenwood = 2pts, add 146.91 = 3pts, also add 449.425 = 5pts.

The Answers for the mystery loads:
  • 1 = 20' of coax shorted. Actually it was connected from port 1 to port 5. Port 5 on the box was modified with a jumper to short that port when it was not selected for use as a matching section for a stack.
  • 2 = a 1000pf capacitor
  • 3 = 50 ohm dummy load
  • 4 = a 2.7uH inductor. The diode on the back of the control box powers port 2 and 4 when you select 4 so it made a parallel resonant load at about 3MHz.
  • 5 = the same 20' of coax going to port 1, but this time it looks like an open circuit at the end because port 1 is not modified.

W1TO YCCC Meeting report:

To celebrate the 25th anniversary of David Robbins’ amateur radio station in Peru, MA a picnic and amateur radio filled schedule of activities was held on July 25, 2009. As a part of the activities a regional meeting for the Yankee Clipper Contest Club was held. The picnic was scheduled to start at noon; however, some of the guests arrived on Wednesday. At least four continents were represented. The food/drink and tent/tables were provided by Harrington’s Restaurant of Adams, Ma. They did an excellent job with a portable grill and beer tap. Dave had 5 games setup for the participants. Each of the game winners received a prize.

  • Guess the number of nuts and bolts in the jar. Winner = KA1HSP
  • Mystery Loads – Given a Time Domain Reflectometer and MFJ-269 meter figure out what is connected to each of the 5 ports of the RCS-8V relay box on the other end of the cable. See Dave’s website for a better description of this. Winner = KK1L
  • Scavenger Hunt – identifying a series of radio related questions at various sites on the grounds. Winner = AC2AC
  • QSO Race – Given a set of equipment get on the air and make a contact. Winner = K2XA
  • Knot Tying Race – Tie a pipe hitch around a ground rod without stepping off the 180’ tower foundation, the ground rod was about 10’ from the foundation. Winner = N1FJ

A brief meeting was held to allow new members to be considered. Two new members were added to the roles: KG2A/JJ1RJR, Kei Fukuda and N2JFS, Hans Hammarquist. KG2A was an active contester in Japan and is now working in New York. Hans is another addition to the Vt contingent.

Dues were collected from the new members and several others. All have been forwarded to the Treasurer. The new member applications have been sent to the Secretary.

In addition to prizes for the games there were several door prizes awarded by a drawing from a YCCC hat. The prizes were provided K1TTT.

Several station and antenna tours took place. The IOTA contest was in process and several operators passed out QSOs.

The attendees were: WA1ZHM, NJ1F, K1SFA, W1UE, W1HIS, K1MK, N1LZH, W1BS, KJ1K, W1TO, K1TTT, N1FJ, N2KW, W1DWA, WS1V, KB1W, K3GM, K2BB, KK1L, W1UJ, N4XR, K1EBY, KC2HQH, K6ND, KB2SAE, K6NDV, N2JFS, KB2VLC, PY2AAZ/AC2AC, W2FK, KB1PHW, W1IM, KE3HT, K1UNF, AA1IZ, K2XA, KB1PQX, KB1NWH, KK1W, KA1HSP, AA1AR, WA1ZAM, K1RQ, KG2A/JJ1RJR, WA2AAU, W1DDW, Walter Bourassa, Isabel Rossi, Sophia Rossi, Glenna Clark, Joe Stergis, Susan Szewczyk and Kate Szewcyzk. Fifty two people signed the sign in sheet.

All in all it was a great day. Thanks to Dave for hosting this fine picnic.
