70cms good conditions tonight

Just worked GW0LJW in Gwent and G3VEH/M via a 70cms repeater in Somerset tonight when running 5W (actually about 1.5W into the antenna after the coax run) into the vertical colinear. Conditions are definitely up in that direction as the distance is about 250kms.

Dutch on-line SDR testing new bands

The on-line software defined radio (SDR) in Twente, Holland http://websdr.ewi.utwente.nl:8901/ (very useful when testing 80m QRP rigs) temporarily added the 0-150kHz, 1.8MHz and 10MHz bands to the ranges with wider band coverage than before on 20 and 80m over the Christmas period. This SDR is now back to its usual 80,40 and 20m coverage (as of Dec 30th).

The South Hams and G5BY on 6m

A slight aside from ham radio, I just want to give a plug for the most beautiful part of England where I lived until leaving for university - the beautiful part of southernmost Devon known as the South Hams. Our family has lived here from at least 1428, the earliest date in our family history records when one of my ancestors owned one fee of land in the time of King Henry VI. You can understand why I still regard this as my spiritual home even though we enjoy living in East Anglia. We still make regular pilgrimages back to "the promised land" as my dear old dad called it. Indeed it is.

There is a new book of walks in this area called The South Hams Coast by Gerry Miles (see www.devonpaint.nl/ and also available from www.amazon.co.uk). The book is beautifully illustrated with coastal walks covering many of the high spots from where some great VHF DX has been worked. These include Bolberry Down from where G5BY worked the USA on 6m back in the 1940s when the band was briefly available. Today his QTH (see old picture) is "The Port Light Hotel" a delightful place to drink a pint or have a crab sandwich on a long sunny cliff top walk.

G4IRZ Silent key sale - items now sold

On behalf of his widow, the kit belonging to the late Len Winnert G4IRZ was sold today, as one lot, to a private buyer in East Anglia.

Radio Nature

A very happy Christmas everyone. One of my presents was the book called "Radio Nature" by Renato Romero which is a very good introduction to the weird and wonderful world of ELF/VLF natural emissions such as whistlers and tweeks. The book, available from the RSGB on-line bookstore, is an excellent read.

Tunnel Diodes rigs

Way back in the 1960s I recall making a simple tunnel diode oscillator as part of a lab project and being excited to see such a circuit used to span 160 miles on 80m by a ZL station despite the power being microwatts only. These days tunnel diodes are almost unheard of.

Recently I spotted a similar tunnel diode TX and RX on AA1TJ's excellent webpages on which you can find more data and links to off-air records made at DX distances.

G3XBM is 60 today

Well, another milestone passed - I have reached the age of 60 and get a free bus pass for local English buses nationwide as well as a winter fuel allowance. At least there are some perks for getting older.

Elecraft K1

This morning I fired up my Elecraft K1 CW transceiver not having used it for some time. It is such a good little rig. Mine has the 4 band unit and internal ATU option and covers 40, 30, 20 and 15m. The filtering is excellent and the user interface good as long as you can remember the menu system, which I forget often when I don't use the rig for a time.

Within a few minutes of connecting the end-fed wire about 15m long into the back of the rig I had 5 QSOs in the log on 40 and 15m. It is such a perfect CW rig.

£500 silent key sale - a REAL bargain!

Some weeks ago I mentioned that I had been asked by a niece of G4IRZ to help with disposal of his (silent key) radio gear which included an Alinco DX70 HF transceiver in original packing and an FT767GX, FP707 PSU and lots of other ATUs, SWR bridges, BC221, GDO, etc. Several requested the list, but no-one has put an offer in.

The whole lot is yours for £500, buyer collects from Cambridgeshire.

I believe the actual value of the kit FAR exceeds this amount but I am not in a position to spend time disposing of the items individually. If someone is willing to buy the lot from his niece she would be pleased (as would Len's XYL) and the buyer is likely to make a decent profit if the items are then resold separately. It would also make an excellent complete ham shack for anyone starting out.

Remember, £500 buys a huge LOT of decent gear for Christmas.

Dec 27th: Now all sold.
