  2. An interesting look at counterpoise use with different rated baluns. I don't own any of their products, but it's an interesting look at the subject. https://www.balundesigns.com/content/Wire Lengths for 4 and 9-1 ununs.pdf

    Field Day 2019

    Also wanted to toss this out for consideration. Rules: http://www.arrl.org/files/file/Field-Day/2019/2019-Field-Day-Packet-Complete.pdf 3.1.Class A and B (see below) stations that do not begin setting up until 1800 UTC on Saturday may operate the entire 27-hour Field Day period. 3.2. Stations who begin setting up before 1800 UTC Saturday may work only 24 consecutive hours, commencing when on-the-air operations begin. 3.3. No class A or B station may begin its set-up earlier than 0000 UTC on the Friday (Thursday afternoon or evening local time) preceding the Field Day period. Cumulative set-up time shall not exceed a total of 24 hours. Event starts at 1800 UTC/ 1300 CDT Saturday. In my short time as a member, we started setup on Saturday morning around 0800. This is before 1800 UTC listed in rule 3.1, which puts us at 24 hours of operation per rule 3.2. So, that means that we could start setting up Friday afternoon (rule 3.3) if we have access to the site. This would give us some extra time to sort out the inevitable issues that crop up, and potentially have some testing Friday night to check for interference. Thoughts?

    Field Day 2019

    Current plan is to use Jeff WD0GTY's trailer for CW operations, and park in the parking area west of the Red Barn. Jeff has generators to support the trailer. This provides 170 feet of distance to the private residence to the northeast of the trailer (northwest of the Red Barn), and a buffer of nearly 400 feet to the residences to the west of the trailer for noise. One of the cool parts of ham radio is experimenting with ideas. Jeff is curious about using a 3-element beam for 10/15/20 attached to the trailer, with an elevation of about 25 feet on military mast attached to the trailer. We were able to complete some proof of concept work today. One concern is how the metal of the trailer may affect the signal. We are also planning to utilize an 80m OCFD antenna, oriented as shown in the picture. The current plan is to have the feedpoint at approximately 40 feet on military mast, and the long leg of the OCFD oriented northwest. The distance from the CW trailer to the north end of the Red Barn is approximately 320 feet. Dave WD5G had mentioned the possibility of using AREDN to link the trailer with the Red Barn. In reviewing imagery from Google Maps Streetview and Google Earth, we have confirmed two overhead electrical hazards in our area. Those have been marked on the diagram. There are utility poles in the area as well, but we can't tell from the imagery if these have overhead lines attached or if they are simply streetlights with underground electrical distribution. I've marked those as well. If you have any ideas, comments or concerns, please advise.

    Field Day 2019

    This material was assembled by Lucien Jones after Saturday's meeting. Per our meeting Saturday at the Atkinson Heritage Center, I have created map and floor plan sketches of what we came up with. After the meeting, some of us stayed around to meet with Cindy Mikeman when she came to lock the place up. Two things were changed per that conversation. 1. The CW trailer will be located further south to respect the private space of the folks who reside in the large house on the north side (see drawing). 2. We initially planned to park the generator/trailer on the north end of the red barn building at the east end of the paved drive. But to mitigate noise for the private residence, it was decided to roll the trailer around the corner on the east side of the red barn building (see drawings). I made the drawings and ran them by Dave, and after making some adjustments per my conversation with Dave a short time ago, I am forwarding them to y’all.

  10. http://www.13colonies.net/ This is fun event to try for a "clean sweep". Special 1x1 calls for the 13 original US colonies (K2A thru K2M) with 2 bonus stations (WM3PEN in Philadelphia, and GB13COL in England). You do not need the bonus stations to qualify for a clean sweep. Shortwave Listeners (SWL) can also earn the certificate. Certificate is $5.
  11. https://70aniversario.ure.es/ 14 special calls to chase with the "AM70" prefix. Contacts can be made using any mode or band from 160 meters to 6 meters with the 14 different AM70 special stations. The suffixes of the 14 special stations are each one of the letters of the URE in Spanish, except the one with the letter "Ñ" which will be replaced by the URE headquarters special station AM70URE. And so, the 14 special station callsigns are: AM70URE (Unión de Radioaficionados Españoles) also AM70URE/6 (Balearic Islands), AM70URE/8 (Canary Islands), AM70URE/9 (Ceuta and Melilla) AM70A, AM70C, AM70D, AM70E, AM70F, AM70I, AM70L, AM70N, AM70O, AM70P, AM70R, AM70S y AM70U Certificates start at just 6 contacts! Silver = 6 AM70 stations Gold = 6 AM70 stations, on each of 3 different bands (18 QSO's) Platinum = 10 AM70 stations on each of 3 different bands (30 QSO's) They are working lots of bands & modes. I've seen them being worked on FT8, and I've seen them spotted on SSB. I've squeaked out one CW contact thus far. And if you don't have HF privileges, you can participate as a shortwave listener!
  12. Where do you get yours? I got my first batch from CheapQSLs. For the money, it's hard to beat. Nothing fancy. $9.99 for 100 cards. Since I moved, the address & grid was wrong. Oops. So, new ones ordered from KB3IFH. Decided to go with a nicer, full color photo version. Randy and I had several e-mails back & forth, working on small details about the cards. 100 cards is $61 including shipping ($50 for the cards, $11 for UPS). You can find templates on line for Microsoft Word and do it yourself.

    Has anyone tried this app? SMS2CW. Grabs text messages as they hit your phone, and converts them to CW. https://sms2cw.en.aptoide.com/?fbclid=IwAR0JG8zuTQRCY0ilq4kdGPmdhI-nM_CLQauF68rtQ6LB7ROpswxf8M8LynY
  14. Did anybody get lucky and catch one over April 1 or 2? I listened on April 2 but never heard them. But, I did sleep in after insomnia with a 1am deal at work. There's supposed to be another SSTV event coming up later this month. From http://ariss-sstv.blogspot.com/2019/ The next big event will be the ARISS SSTV event that starts Thursday, April 11 about 18:00 UTC and will be operational until about 18:00 UTC on Sunday, April 14. Since this event will run continuously for 72 hours, folks in the higher latitudes should have a pretty good chance to receive all 12 of the images. Operators in the mid latitudes should be able to get most of them depending on location.
  15. There is an International Space Station thing coming up April 1-2. You can learn more over in the Amateur Satellites forum. There's free software for Android (probably Apple iOS as well, I just don't use that platform) that will listen to the audio from your radio and convert the SSTV (slow scan TV) data stream into an image. I've never done SSTV stuff, so I may be giving it a try. Dave WD5G gave a presentation on the software at a recent club meeting.
  16. Hi Charles! As I understand it, the hot times for most of the repeaters are during the morning & afternoon commutes. I know OCAPA has a net on Thursday nights at 7:30pm, and EARS in Edmond has one on Monday nights at 8pm. I don't spend much time on 2m. I'm in a company vehicle during the week, so no way to install a permanent radio. I have taken my HT and used a mag mount antenna before, and experimented a little with DMR (which needs no external antenna). Hopefully some of the other guys will chime in as well. Welcome aboard!
  17. Looks like another opportunity coming! R4UAB reports SSTV images will be transmitted from ISS Russian Service Module 145.800 MHz FM using Kenwood TM-D710 & PD-120. Expected between 1400-1900 GMT on Monday and Tuesday, April 1 and 2. http://ariss-sstv.blogspot.com/2019/
  18. SOTA is a lot of fun! There are two roles: activators and chasers. Activators carry their gear to designated mountain peaks. You can work any band, any mode with the exception that you cannot use repeaters to make contacts. However, you can use the repeater to ask people to switch over to a simplex frequency and make contacts! If you make 4 valid contacts, you get to claim the points for the mountain. But you can only claim points for a designated summit once in a calendar year. Chasers usually sit at home, in the comfort of their shack and watch the SOTA spotting website and try to work activators. If you log a valid contact, you get to claim the points for the mountain. CW is very popular, even slow speed. I've worked stations at 8-10 words per minute. And, activators will gladly slow down to your speed. Most exchanges are very basic - signal report and state. 3 digits, 2 letters. CW is very popular because it is much more efficient at low power than SSB. Kyle NQ5M
  19. We operated multi-multi from a remote site in Kiowa county, owned by one of Jeff WD0GTY's coworkers. Jeff's Rig: 80m OCFD antenna, oriented east-west on 28' feet of military mast Kenwood TS-480 Bencher Mercury CW Paddles Laptop running N3FJP logging software, K1EL WinKeyer Perry's Rig: 40m OCFD antenna, oriented north-south attached to the trailer, 28' of military mast Icom IC-7300 Bencher Mercury CW Paddles Laptop running N3FJP logging software, K1EL WinKeyer We drove out to Kiowa county, south of Roosevelt, Friday after lunch and started setting up. We were able to get the trailer leveled and secured, then started working on setting up antennas. We drove back into Hobart to eat dinner at Big A burger. And that's not "BIG A" burger, it's pronounced "BIGGA" burger! A big concern was the weather. Friday night had a thunderstorm move through, and some strong winds. Everything stayed up, but the stand-alone military mast needed the guylines tightened up. We worked on fried bacon, eggs, toast & coffee, and then got to work on the radio. The weather on Saturday was awesome! We left the side door and the rear door of Jeff's trailer open most of the operating session. The downside was some of local insect population -- including yellowjackets -- were already out and about. We feasted on fried catfish nuggets and fried potatoes & onions. Saturday night turned much colder, with another round of wind. Sunday morning was coffee, biscuit & sausage gravy. And the task of tearing down in the cold weather and driving winds. Jeff & Perry setting up the radios Jeff checking the 80m OCFD Jeff likes the catfish nuggets & fried potatoes Jeff working on an issue with the Winkeyer while Perry works Jeff is looking for a clear spot on 40m Jeff's Kenwood station. The head of the unit is on the table, while the transceiver is on the shelf above. This was a cool thing, as it saved a lot of table space. Bencher Mercury key is on the right. Kyle operating Perry's IC-7300. More of Kyle on the 7300. I moved his Bencher Mercury back, and hooked up my N3ZN keys ZN-9Z for the CW work. My CW has improved enough that Perry can take a break rather than babysitting me 🙂 Perry works to dig a station out of the noise. Perry testing the Bencher Mercury with the WinKeyer. Surprise! The uneven terrain made antenna setup..... interesting. 28' of military mast with a yardarm on Jeff's trailer. Note that the trailer is level, and the ground ain't so much. I'm in the back of the trailer, probably running coax or something.

  21. I've seen a few 3D printed ideas out there, but wasn't sure if Duane had a case in mind yet or not. I have a friend in Sapulpa studying for General, and have thought about buying a uBitX as a "graduation" present for him.
  22. Saw today (2/21/19) that one of the common aftermarket cases for the uBitX builds is on sale for $8.99. https://miscdotgeek.com/qrp-bitx40-and-ubitx-case-on-sale/?fbclid=IwAR3enPxSlYh4jeCAO0dWoDdwKt6KSCZhxSFzRefIQgWRc-mBsSjMc7w0qRA
