Back from Christmas break

There’s been a bit of radio silence over the last 2 weeks. mainly because I’ve not been at home. We spent Christmas and new year up in Scotland and then I started a new job last week away was away from home for 3 days. Hence the quiet conditions. I prefer not to broadcast that I’m away until after the event, just in case.

I did have a couple of hours listening in for the Christmas cumulative but only worked a couple of stations that were very close. Apart from that Santa dig bring me a new antenna for 6m, which was interesting on the way home (My journey down was spent hoping that the cardboard tube would stay in tact, despite torrential rain). This has prompted me to have a rethink about my shack and what kit is going where, what I need and what I can sell on. Plenty to think about.

I hope Santa was good to you and here’s wishing everyone an active new year.

Yet Another HT From China (Baofeng UV-B5)

I happened upon this posting from Hans PD0AC about the Baofeng UV-B5 handheld transceiver. Hans has written a number of useful reviews on the El Cheapo Radios from China, so when he wrote “The Baofeng UV-B5 is close to perfect”, it caught my attention. I have a couple of the other radios from China that I blogged about here and … Continue reading …

My #hamr Weekend Update

Winter Maintenance

Good evening from the Shell Beach shack as the Kenwood TS850S listens on 20m CW through a trapped vertical between a pair of condominiums. I’ve noticed a significant uptick in activity as the weekend roller coasters into Sunday. Truly, it is good to hear signals on 15 and 20m with a bangin’ sunspot count of one hundred and sixty seven!

If this number remains stable through the night into tomorrow my plan is CW all day long.

In the meantime, our break in weather has allowed time for antenna maintenance and one reflector on the KLM, 3 element 40m yagi, at SL’s antenna ranch is going through corrosion treatment. Our local marine environment is terribly corrosive and fighting it is an on going test of patience. The climbing standing wave ratio reached a point of diminishing performance.

We are taking down one element at a time instead of the entire antenna. This afternoon all the hardware on the rear reflector featured in the photograph was removed for cleaning and/or replacement. Additionally, alkaline was removed from tubing intersections and intersections were thoroughly cleaned. Likewise, linear loading hardware was removed with contact at elements given a good scrub with wire brush to remove deposits.

John is going to check intersections for continuity prior to re-installing the removed reflector.

I’m stoked to see best numbers in a long time and looking forward to tomorrow’s CW marathon session inside my Shell Beach shack.

Life is wireless.  



Never too early – less than a month away!

Happy Three Kings or Epiphany – and to our Orthodox brothers and sisters, Merry Christmas!

Now that the Christmas season is approaching its end (next weekend for Roman Catholics), it’s not too early to start to think about the inaugural outdoor QRP event for 2013 ……..

Freeze Your Buns (or Butt, if you prefer) Off – which should be held the first Saturday of February – the 2nd, which is also Groundhog Day.  So you can freeze your body parts off operating in the Arizona ScQRPions QRP sprint, while simultaneously keeping an eye peeled for groundhogs!

There hasn’t been any official notice of any rule changes for 2013; so if you’d like a refresher on the rules that were used last year, click here.

Last year I made 11 contacts using my PFR3A and the Buddistick on top of the car, and the temperature when I started was 45F (7C).  Accuweather is predicting colder than normal temperatures for the second half of January and all of February.  That would be good for a better multipler; but not so great, comfort wise.

Let’s hope that it’s not like THIS, that day! Or worse yet …. like it was the day before!

SDR-Radio and Omni-Rig

Yesterday I thought I would set up my Cross Country Wireless SDR-4+ receiver to use for IBP beacon monitoring using Faros. The purpose of this was mainly to reduce the wear and tear on my Elecraft K3 which otherise would have to be on 24 hours a day.

I established that Simon Brown’s SDR-Radio software supported external program control by emulating a Kenwood transceiver. I therefore needed to see if SDR-Radio could be controlled using Omni-Rig, the control mechanism used by Faros.

SDR-Radio supports CAT control using a virtual serial port.

I created a linked pair of virtual serial ports, COM8 and COM9, using VSPE, a virtual serial port emulator. Using the serial ports option of SDR-Radio, I assigned the control port to COM8. Then I used a serial port emulator connected to COM9 (I use RealTerm) to verify that SDR-Radio ‘spoke’ Kenwood. It did. In fact it emulated the Kenwood protocol well enough to fool KComm into thinking it was talking to an Elecraft K2. So far so good.

Now to see if Omni-Rig could control SDR-Radio. Omni-Rig uses “rig files” to define the command set of different radios and it includes one for generic Kenwood. Unfortunately it did not work with SDR-Radio: the receiver indicator of Faros turned red to indicate a fault.

I downloaded the rig file documentation and debug tools from Omni-Rig’s site and tried hacking the Kenwood rig file to get it to work with Omni-Rig by trial and error. But no luck. Whatever I did, the program reported an error with the inscrutable message: “RIG1 Status commands already in queue”.

Error messages reported by Omni-Rig

So it looks as if I’ve hit a brick wall. Clearly there is something in SDR-Radio’s emulation of the Kenwood protocol that Omni-Rig doesn’t like. If anyone else would like to have a go solving this problem, be my guest.

ARRL Vintage Amateur Radio Equipment Exhibit

Credit goes to Jeff, KE9V for illuminating this terrific video about vintage Amateur Radio apparatus taped at League headquarters and narrated by ARRL Engineer, Bob Allison, WB1GCM. As mentioned at Smoke Curls, the 4 minute video is well worth your time, if for nothing else, actually hearing what a spark gap transmitter sounds like! It sounds like an electrical shock gone wrong.

ARRL Vintage Amateur Radio Equipment Exhibit: While it’s important to look forward to tomorrow, it’s equally important to understand the evolution of radio equipment that was used on the Amateur Bands; from the earliest “spark days” to the dawn of digital technology. By delving into the past, one can learn to appreciate the hard work, determination and experimentation that brought us one step at a time, the technology we enjoy today.
