1 N5GHZ President: Bill Musa, K5YG Vice President: Anthony Allen, W6CSA
Formed December 2010 N5GHZ KF5JKC – Applied for N5GHZ President: Bill Musa, K5YG Vice President: Anthony Allen, W6CSA Secretary: Victoria McKitrick, K5EYK Board Member: Glenn Martin, N5PQ Board Member: Bob Delaney, WN2E

2 The World Above HF & VHF/UHF DX presented by Bill Musa – K5YG January 9, 2011 Video
(Video produced by JACQUE “JD” DUPUY, N0IRS)

3 VHF/UHF Operations There is something for everyone:
Terrestrial – all modes Line of sight Tropospheric (Tropo) Sporadic E (E-Skip) F2 Skip on 6M Satellites (Up and Down Link on various VHF/UHF bands) RS-12 Satellite used 15M up with 10M down Meteor Scatter (M/S) (6M and 2M) Moon Bounce (EME) (6M thru 1.2Ghz)

4 “The VHF/UHF DX Bug” bit Bill in 1965
Highlights for K5YG 1965 – Made some of the first contacts via the OSCAR Satellites. (2M up / 2M down – low orbit) 1965 CQ Spring VHF Contest – High Score 2M 1970 – Worked W5WAX in Oklahoma (1180mi,) on 2M via Aurora over 40 years ago, from NJ (Then again (K5SW) in 2008 from MS on 2M CW and SSB) 1995 – Worked All States via Satellite (ARRL OSCAR Award #214) 1995 – AMSAT W4AMI Satellite Operator Achievement Award #6 for 1000 Satellite QSO’s Working N0IRS & N0IRC in Kansas City, MO (700mi) on 2M Working N4TUT in FL (450mi) on 70cm from the O.S. Bridge Working N4TUT in FL (450mi) on 23cm SSB (Both running only 1 Watt) 2009 – Working all over USA and Europe on 6M 2010 – 2M E-Skip Opening June 19, 2010 – Maybe the best ever K5YG EM50 to N0IRC EM29 Recording (Video produced by JACQUE “JD” DUPUY, N0IRS)

5 1970 contact with Sam, W5WAX

6 1967 contact with Barney, now K3FM

7 VHF/UHF Propagation 6M – Normally line-of-sight
Sporadic E Propagation –All over US with multi-hop to Europe F2 Skip on 6M during Sun Spot Cycle High – world wide Meteor Scatter every morning – work all over US 2 M – Normally line-of-sight Tropospheric (Tropo) Propagation - 500mi Sporadic E Propagation (E-Skip) mi + Back Scatter – strange sounding signals 100mi Meteor Scatter most every day, peaking during major Meteor Showers. (1500 mi about the limit on 6 & 2M) Moon Bounce (HS Via WSJT by K1JT) or via CW – world wide 70cm & above – Normally Line of sight Occasional Tropo Propagation, most of the time 70cm is better than 2M. Moon Bounce

8 F2 Skip during Sun Cycle High
Don't hold your breath for this one, but be aware of its potentialities. This is the familiar long-haul skip which bounces shortwave signals around the world in hops of roughly 2000 miles each. During sunspot peaks F2 may extend up to 60 mHz, opening American channel 2 to DX, plus a number of European, African and Oceanic TV stations operating at these frequencies and below. F2 activity is greatest in years of peak sunspot activity. As sunspot activity increases, F2 MUF also rise. F2 at VHF frequencies is not probable in years of low solar activity. If you want to keep track of F2 conditions, which tend to peak in the spring and fall, monitor on a mHz radio. Paging stations beyond 1600 miles or so on 35 and 43 mHz will give you a warning when F2 is "up".

9 What does it take? (IC-706, IC-7000, IC-910H, FT-897D, TS-2000)
Multi-mode SSB/CW/FM - HF/VHF/UHF Transceiver (IC-706, IC-7000, IC-910H, FT-897D, TS-2000) Low Loss Coax such as LMR-400 Mast mounted Pre-Amp desirable Most using Horizontally Polarized Antennas Yagi, 2M Big Wheel, 6M Dipole, Vertical Only Watts needed during good opening 300W or more best for Meteor Scatter

10 VHF/UHF Calling Frequencies
6M – SSB Calling: , CW 6M – Beacons below 6M – HS Meteor Scatter: 2M – SSB and CW calling 2M – HS Meteor Scatter 2M – EME 1.25M (222 Band) SSB & CW 70CM – SSB & CW Beacons and above K5YG/B Running 10 watts 24/7 into HO Loops 23CM – SSB and CW Schedules: Usually 5-10 up or down from calling frequency Rag Chew: Move off the calling frequency

11 When is 6M and above open? Being there at the right time!

13 APRS Automatic Packet Reporting System 144.390
APRS was developed by Bob Bruninga, WB4APR, as a real-time local tactical communications system for rapidly exchanging digital data of immediate value to operations. This really took off when GPS became available and MAPS were integrated into the system for tactical situational awareness of everything in the net. In the 13 years since its introduction, it has grown to encompass just about every aspect of Amateur Radio.

19 Very good opening into TX, AR, TN and FL

20 Sporadic E July 26, 2008

21 Sporadic E July 1, 2008

22 The “Big one” 2M E-Skip Opening June 19, 2010

23 World above HF Get on 50.125, or 144.200 and make some “noise”
There can be a Sporadic E opening on 6M anytime of the day The 2M APRS Map does not always tell the truth! Call CQ in the early morning and evenings (If everyone listens the bands appear to be “dead”) Plenty of activity during Contests

24 VHF/UHF Contests Anyone?
Great way to check out your equipment Your home station Rovers Fixed Contest Stations Portable “hill top” stations Great opportunity to make contacts toward ARRL VUCC (VHF/UHF Century Club)
