RadCom and the IC7300

My RadCom arrived by post today. Unlike in the recent edition of PW, the advertisers were publishing details of the new ICOM radio and were keen to take deposits. Perhaps they have got later data? I quite like the look of the new IC7300 radio, but feel the price will soon fall to £799 or less. I can wait. I may wait to see what the FT817 replacement looks like. A 5W (or maybe 10W) radio would suit my needs better.

The latest RadCom has a review of ICOMs latest flagship radio, the IC7851, selling for around £9000. Does anyone really spend this sort of money on amateur radio gear?  With PSU, tower, big beam and big rotator this implies over £10000 on amateur gear. I suppose some people must spend this sort of money. My FT817 has served me for over 14 years now. To me, this was an investment and I had to give it careful thought.  I wonder how many XYLs are happy for their husbands to spend over £10000 on a hobby?

Each to their own. If you really have that kind of disposable income how you spend it is your decision.

Religion and Ham Radio

300px-International_amateur_radio_symbol.svgWe need to get the religion out of ham radio. No, I am not talking about the HF nets that support missionaries or similar activities. (Those people might actually be doing something good for the world.) I am talking about the religious debates concerning new technology…this technology is better than that technology.

Amateur radio is a technical hobby, one based on technology, hobbyist pursuits and mutual interest. One might think that this means issues are looked at objectively and discussions are based on logic, scientific principles and facts. Of course, this is completely wrong. What often shows up in ham radio are religious debates about technology or operating modes.

Here’s a definition of Religion:

a specific fundamental set of beliefs and practices generally agreed upon by a number of persons or sects: the Christian religion; the Buddhist religion.

You can tell when you are stuck in a religious debate…the facts quickly fade and statements like “this is the right way to do it” become louder. Underneath this is a fundamental belief trying to come out that the person may not even be aware they have.

A long running example of a religious debate is Linux versus Windows. On the surface, people argue about which one has more defects, which one is more secure and which one ultimately serves their needs better. Underneath the surface is the religious belief: software should be free, Microsoft is evil, etc. Then there are those Mac enthusiasts (you know who you are)….these folks tend to act like a cult as they attempt to convert other people to their group. (Where is the line between enthusiast and cult member?)

The latest one on the ham radio front is the debate over digital technology in the VHF and higher bands: D-STAR versus DMR (and now Fusion). The debate starts out rational with a discussion of the merits of each but soon the deeply-held beliefs come out: D-STAR is bad because ICOM is pushing it, DMR is good because it is the commercial standard, D-STAR is good because it is an amateur radio standard, D-STAR uses a proprietary vocoder chip so it is bad, etc. Then don’t forget the guys that say “all digital is bad, analog FM is good.”

Again, you can tell when the religion kicks in because the facts start to fade and the beliefs rise to the surface. Usually, these arguments can’t be resolved because you can’t really debate beliefs. What you get instead are flame wars on the various email groups.

What other religious debates are out there? Android versus iOS, Open Source Software versus Commercial Software, My favorite rig versus Your favorite rig, … what else?

630m Crossband Schedule

VO1NA Torbay, Newfoundland
Following up my last blog posting, the weekend of November 14-15 has now been confirmed for the '630m Special Activity Event' . There will be further details coming regarding the various experimental activities and transmissions but the one that holds the most interest for myself is the 'crossband' operation by several Canadian amateurs.

There are now five Canadian amateurs slated to operate over the course of the two-night event (Friday & Saturday) and they will be looking for two-way crossband contacts with amateurs in the U.S. and Canada. Here is the schedule of frequencies and times:


Station: VO1NA (Joe) GN37 Torbay, Newfoundland
Time: 2130Z - 0130Z both Friday night (Nov 13-14Z) / Saturday night (Nov 14-15Z)
TX Frequency: 477.7 kHz
RX (QSX) Frequency: 3562 kHz

Station: VE7SL (Steve) CN88 Mayne Island, B.C.
Time: 0200Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 473.0 kHz
RX (QSX) Frequency: 3566 / 7066 kHz

Station: VE7BDQ (John) CN89 Delta, B.C.
Time: 0430Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 474.0 kHz
RX (QSX) Frequency: 3536 kHz

Station: VA7MM (Mark) CN89 Coquitlam, B.C.
Time: 0500Z - 0700Z Friday (Nov 14Z)
          0400Z - 0800Z Saturday (Nov 15Z)
TX Frequency: 475.0 kHz
RX (QSX) Frequency: 3570 kHz

Station: VE7CNF (Toby) CN89 Burnaby, B.C.
Time: 0300Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 476.0 kHz
RX (QSX) Frequency: 3558 kHz / 7062 kHz



These stations will be calling CQ on CW at regular intervals throughout the evening, and listening for answers on the allocated HF call-back (QSX) frequency. The sequence that I will be using (and others in a similar fashion) is:

"CQ CQ CQ de VE7SL VE7SL VE7SL QSX 3566 and 7066kHz K". After listening for callers on either QSX frequency for approximately 30 seconds, the CQ will be repeated if no callers are heard.

With good conditions, propagation can often span the continent, so please consider taking part in the activity from wherever you might be located in North America. Last year, crossband contacts were made between here and W3 / W5 and many points in between.

For eastern stations, VO1NA, in Newfoundland, should be a tantalizing target with coverage throughout the eastern states while the four VE7 stations should prove workable for central and western North American amateurs.

Those that might wonder about the 'legality' of crossband contacts need not worry. Canadian amateurs have had legal access to 630m for almost two years now and crossband contacts with any stations in the amateur radio service are the same as a two-way QSO on any other band. Unfortunately, amateurs are not allowed to contact any of the experimentally-licenced stations ... they are permitted to work each other only.

Hopefully you will print out the operating schedule and consider participating in the November crossband activity weekend ... the more the merrier! It would be great to see even more contacts than last year, which was a great start, considering the less than optimum conditions. I will post more details as the event weekend draws closer. We hope to see you there!

DX and Fall Colors

Judy and I took a walk near Hunkins Pond this afternoon. The fall colors were at their best! 20 meters was pretty good too. I worked Cuba, the UK and Rhode Island.

field

We hiked west and north on the old range road. When we got to David Swain’s north field, we turned in. The view was stunning. Even though the true temperature was 55F, in the sun it was almost 75F. I set up the Par 3-band end fed wire as an inverted vee over a maple branch and sat down in the sun. It was glorious.

jim

I was running the KD1JV Mountain Topper at 3 watts. As I tuned down the band, I heard T47GDXC calling CQ. This is a special event station from Cuba. We exchanged quick 599’s and I was glad to have one contact under my belt. I had an ear to stations on the band and both eyes on the fantastic view.

view

Tom G3HGE from England was working one station after another. He and I are old friends and I was anxious to work him again. I called several times but other stations beat me to it. Finally, I got my chance and called him in the clear. “PID?” he sent and I returned with my call sign several times. At last he copied my call and we had a wonderful exchange. He was a solid 569, but I was only 339 to him. “UR signal is dropping to S1,” he sent as I told him I was operating portable in the beautiful outdoors. We signed after a couple of minutes, but I was thrilled to complete a QSO with him for the first time in a month or so. My little Mountain Topper sat in my lap with a notebook on my knee. You’ll see Tom’s call sign in the notebook.

rig

I switched to 40 meters to see how that band was and heard Joe N1EFX in Rhode Island right away. He was calling CQ with a solid 589. He gave me a 449, but copied well, and we chatted for several minutes before signing.

I was satisfied with the contacts and wanted to hike down through the fields a bit before heading home. We headed east and south on the range road and came to Dearborn’s Farm. What a wonderful spot. Shimmering green grass, trees aflame in gold and corn over 8 feet high. We headed into a quiet glen and I took a quick snapshot.

These glorious days are so fleeting. Tomorrow and the next day it’s supposed to rain. We may lose much of the color.

Better with SMA

I had some trouble closing the lid on the “Just good enough 10 MHz GPS reference” due to the size of the BNC jack. Therefore I changed it to an SMA (SubMiniature version A) female jack. A thin cable connects it to the K3’s SMA input and there is no need for any SMA-BNC adapter on that end.

At the same time I moved the GPS antenna to a more central location in the tin, in the hope that the walls of the tin would interfere less with GPS reception. That’s the theory anyway, if it matters much in practice is a different story.

Actually, I think I’m going to use SMA more often with these clear top tins and also Altoids tins. They take up much less space and are easier to install and to work with.

There aren’t any high power applications for circuitry in such tins, so I cannot so any reason why the SMA won’t work just as well or even better than the BNC.
