My internet saga continues - positive outcome on cable at new QTH

Yesterday I reported that at the new QTH our new home was the only one on the close that was unable to get fibre optic broadband, phone and TV services from the provider I currently have used for over 12 years: Virgin Media.

Well, today their field engineer surveyed the road and has confirmed that we WILL be able to get cable services at our new place after all. They were very quick checking this - I only asked yesterday - and it looks like everything will be ready for when we move mid-August.

KX3 purchase?

For the last 6 months I have been saving the pennies in my amateur radio kitty towards the purchase of a new transceiver for general use at the new QTH. I am still very tempted to splash out on a new KX3 from Elecraft, despite the high UK cost when fully loaded with auto-ATU, narrow roofing filter, battery pack, charger and mic. As I tend to hang on to gear for a LONG time, this may be a good investment. All the www.eHam.com reviews are very good and it does appear to be a first class radio. What bothers me though is that for the same price I could buy 2 FT817 transceivers and still have change! My main interest is e weak signal mode experimentation and I am not sure that the KX3 is an ideal radio for use as a base rig for this application: there seems to be a need for lots of cables to connect to a PC, whereas the FT817 is easy using a Signalink USB interface.

As was the case when pocket calculators came on the market in the 1970s, the default position here is to "wait and see", which means I buy nothing and hope that a clear winner becomes obvious in the months ahead. In the 1970s I ended up not buying a scientific calculator at all, HI.

Ending operations at this QTH

Nearly the end of an era (37 years) at this QTH. I will resist taking down the antennas until the last moment in a few weeks from now, but already my mind is turning to the new QTH.

Would you believe it, but every house in Mill Close, Burwell is able to get Virgin Media apart from ours! Even next door they have it.  I contacted Virgin Media who have agreed to send out a field engineer to check why this is. The CATV box on the pavement is about 4m from our drive. It is not the end of the world: I can revert to Sky (or BT) phones, TV and broadband and get over 10M download speeds but I will wait until the VM engineer feeds back his findings as it would be preferable to stick with our current provider. Virgin's broadband is VERY reliable and fast.

I now have a firm plan on where to erect the VHF/UHF antennas. The earth electrode antenna for VLF/LF/MF will be installed in the next few weeks. I have still to decide on the location of HF wire antennas in a way that is "sleuth" i.e. low profile and not obvious. Our new patio is right outside my new shack, so operating in the garden should be very easy and fun.

Going batty

We are spending a few days with our son and family near Canterbury where he lives in an 18th century cottage not far from the school where he teaches. In the last few months their home has become an hotel for a colony of tiny pipistrelle bats who have taken up residence under the centuries old tiles on the side of the cottage. A bat expert estimated there are at least 300 living there.

This evening, as the light faded, we watched as they  flew out from what appeared like impossibly small gaps in the tiles. Bats are a protected species, so they are not allowed to get rid of them, but apart from their tiny droppings they are not a nuisance. It was quite amazing watching them fly off for food this evening.

IC-7100 UK price: £1249.99 from Martin Lynch

The IC-7100 multi-mode multi-band 100W radio is now available for £1249.99 including VAT from Martin Lynch. Although not yet in stock this is the price advertised, which is some £500 less than I was expecting. Considering it includes all the HF bands, 6, 4, 2 and 70cms this is not bad value. I just hope the touch screen is not tacky and unreliable. See http://www.hamradio.co.uk/amateur-radio-main-equipment-mobile-radio-icom-mobile-radio/icom/icom-ic-7100-pd-5020.php .

New VLF tests from Germany

News from Germany of an upcoming VLF test at 8.970kHz using earth electrodes as the TX antenna with an ultra-stable Spectrum Lab derived signal.

Hello Group,

 

We are planning some VLF-activity at 8970Hz during a meeting of  electronic hobbyists nearby  Kassel / Germany (JO40vr) on this weekend.  The plan is to run a VLF-PA between some ground electrodes. Due to other activities we have no exact time plan, when to start. Depending on internet access i will inform you about the details. 

 

Thanks for looking for our signal in advance.

HF activity - the weakest maximum in 100 years?

Space.com reports that the peak of cycle 24 is likely to be the weakest for 100 years with the next one likely to be even worse. See http://www.space.com/21937-sun-solar-weather-peak-is-weak.html .

Although I venture onto the HF bands every few days usually, I've not found the level of activity, excitement or interest that I had in previous solar cycle peaks. On 10m back in the 1979 peak the band was filled with stations at any time in the day, even outside of contests. There just doesn't seem to be the same level of activity these days? Perhaps it is because having worked over 100 countries with just a few watts, many on SSB, there is, for me, less interest in chasing DX now. Also, I tend to enjoy more creative parts of the hobby whether on VLF, lightbeams, etc. and don't have the time (as much) for HF operating where the competition is often from ill-mannered, QRO stations more interested in their egos than the ham radio spirit.

Crystal Set DX log from 1991

As I clear out my stuff ready for our move, I've discovered my Crystal Set DX Log from 1991, which was 2 sunspot cycle peaks ago. Looking through the entries in the log (all received with a VERY simple shortwave crystal set using a toroid, a germanium diode, a resistor and a crystal earpiece and a longwire antenna about 15-20m long) it is quite astounding how the HF world has changed.

Shortwave Crystal Set DX log - from 1991

For a start, many of the coast radio stations used to transmit in CW on HF and these could often be read due to the cross-modulation from other stations. This was the technique used to detect those shown in the log above.

Also, the shortwave bands were still filled with English language broadcasts. In the few days covered by this log I managed to receive broadcast stations from Cuba, UAE, India and Australia directly (not via relays) as well as plenty of Europeans. Before this date I had no idea that worldwide reception on a crystal set would be possible.

There is no doubt that conditions were very good back in 1991 and I am not so sure that it would be possible to repeat this in 2013, but I would be delighted to hear of success by others with crystal set DXing on HF in more recent times.

I still enjoy crystal sets: they are simple and fun to make yet there is still something unbelievably good about using the electricity from the TXing station to hear them, not my own, especially when the signal comes from very far away.

IC-7100 UK launch July 17th at Martin Lynch

A few hours after I commented on the price in the US of the IC-7100, I had an email from Martin Lynch and Sons announcing the UK launch on July 17th.

There is still no information that I've seen that gives the likely UK price although I doubt one will be in my new shack.

The IC-7100 is bound to cause a lot of excitement as it is one of the first commercial multi-modes to include 4m (70MHz). The press release seems to indicate that D-star will be supported in the standard product i.e. my understanding is this is NOT an optional add-on, but you get it with the basic product you buy.

The pdf leaflet on the IC-7100 is now available.

Weather boots for coax plugs?

I'm looking for what I believe are called "weather boots" to slide over the end of PL259 and BNC coax plugs to help protect them up the mast from water ingress. I guess it is still necessary to add a smear of silicone grease. There are such items for Sky dish F connectors (see eBay item 251296277220) but I have not yet found a source for the common 50 ohm plugs.

Anyone know where such rubber/PVC boots can be obtained please?
