HamRadioNow: CQ ‘Comes Clean’ (a click-bait title)

There’s something that just didn’t sink in as I interviewed CQ editor Rich Moseson W2VU at the Orlando HamCation for this episode. CQ is in trouble, and advertising is the problem. Or rather, lack of it. Rich said that while subscriber numbers are important, the real revenue comes from ads, and the ham radio manufacturers and retailers that had been buying the ads in the magazine can’t afford to buy them, or as many of them, today.

Subscriber numbers bring in advertisers, of course, but if the companies can’t afford the ads, it doesn’t matter. And I got that, for a minute or two, but then I sort of lost the concept. But the bigger connection I didn’t make until maybe the 10th time I watched the interview (yes, I do that, because I like to hear myself talk) was that ads in the digital version of the magazine are an even tougher sell. So if CQ were to go all-digital to save printing and postage, it wouldn’t help enough. They’d make even less money because they wouldn’t get many of the ads that they do get now. At least that’s my takeaway.

It’s not just CQ and ham radio – digital media, including print, audio and video, isn’t valued as much as “traditional” media, even if the audience is the same. I’m no expert in this, but that’s the conventional wisdom I read in the trades.

One other thing to consider before you watch the episode is that sub-$50 Chinese HT you marvel at. They don’t advertise or support ham radio in any way other then selling you a radio for peanuts. Some of their distributors are beginning to advertise for them, but the companies themselves are still mostly a cypher here in the US. I’m just sayin’….

What will solar cycle 25 look like?

We now seem to be, on average, on the downward slope to the next solar minimum. Some are predicting that the next peak will be almost a non-event with the sunspot number peak of just 7. Of course no-one really knows, but I think it is true that most experts now think cycle 25 will be very poor. Conditions on LF/MF are likely to improve but decent F2 propagation on 10m is likely to be rare, except perhaps with N-S paths over the equator.  What is certain is no-one is really sure. Summer Es could well be the dominant DX mode on the higher HF bands.

UPDATE 2048z:  I have now gone QRT (for the night) on 10m but I will be on 160m now and overnight. Back on 10m tomorrow morning after breakfast.

AM on 28MHz and up

Much to my surprise, the RSGB actually published my recent letter to their “The Last Word” column in RadCom, together with a (pathetic) reply from their Spectrum Chair. At least my letter was printed.

The response did nothing to address my concerns. Although the RSGB claims not to be anti-AM, you’d find this hard to believe with a look at the most recent band plans. AM has its place on all bands from 28MHz upwards. I just wish the RSGB and other national organisations would simply acknowledge that this mode has its place. It may be a minority interest mode, but in my experience it is the simplest mode from a building viewpoint.

Internet of Things (IoT) already here

 This morning I received this email from KK4HSX saying that (certainly in the USA) Amazon is already selling wifi connected slow cookers called “Crock Pots”. Not sure if this is a stateside generic term.

It’s already here. Behold,the Crock Pot you can monitor and control with you phone.

Landwade

Landwade was the site of my first “over the horizon” optical tests. The tests were successful, but predate my stroke by some time. I remember well being surprised at the reception when “on beam”.

We go here each year about this time for a delightful walk of about 1.5km calling at the small private church (locked these days). The church is surrounded by seas of snowdrops and aconites at this time of year. Landwade is very quiet at all times. It is in Suffolk but was in Cambridgeshire until 1994. It has been occupied since Roman times, but consists of a few farms, a hall and the odd cottage these days.

I have updated one of my other blogs.

A pity we don’t have an 8m (40MHz) band.

An amateur band at 40MHz would be really useful as I suspect the F2 MUF has been in this region several times in the last few years. There are a very few beacons around 40MHz (UK and Denmark only I believe) but wouldn’t it be good to have even 100kHz around this frequency? Sadly it is very unlikely, but I would happily lose 100kHz at the top of 10m in exchange.   It would also be a very useful Es band.

Somehow I can’t see this happening, more is the pity.  The world of radio science would really benefit. This would have been so much more useful than 146-147MHz recently released to UK amateurs by NoV.  I know a handful of UK amateurs are trying narrowband DTV but the 2m band is mainly Japanese “black boxes” and is mostly white noise in most areas.

Tenner 10m CW transceiver

Click for bigger image.

The Tenner is a very simple CW rig for 10m. It produces about 500mW output and has worked across the Atlantic on many occasions. Offset RX-TX seems to work out at about right, although no special circuitry is employed. This simple circuit just works. Although I used an “at hand” SBL1, any double balanced mixer is likely to be OK. Although I did not try it, a homebrew DBM would be fine.
