10m QRP homebuilt
With my posts about low cost ways of getting on to the 10m band don't forget homebrew. On my www.g3xbm.co.uk main pages there are details of several simple 10m rigs including the incomplete DSB transceiver for the band that I MUST complete when my health (and soldering ability) returns. Look for 10m Simple Sideband. My plan was either a VXO controlled rig or a mixer-VFO rig covering 28.4-28.55MHz where most sideband activity is. It could also switch to the CW and beacon bands. At the moment my "build" projects are on hold because of my poor health.

£150 10m radios
There are several varieties of 10m radios available for just under £150, brand ne
w, nowadays. One example is the Alpha 10 Max and this (CB oriented) video is a walk-through of the radio. See http://www.youtube.com/watch?v=VFK20rmQayg . See also http://www.youtube.com/watch?v=Cw7Qjrk01Vc . If you are only interested in 10m (28/29MHz) this sort of radio may be a low cost way of getting on the band although they are basically CB radios.
Many years ago I used a Lincoln President multi-mode 10m 10-20W radio and I was able to work the world using it. One of the best QSOs with it was a solid QSO from the car whilst actually driving around the outskirts of Cambridge one evening with an SSB station in India. The antenna was just a base loaded whip on a mag mount. It was a very good little radio. Sorry I sold it really. For a video of the Lincoln President see http://www.youtube.com/watch?v=hDUyLwFc2Pc .
There is a newer,smaller, version of the President Lincoln will be available for around £249 from mid-January. See eBay for details of suppliers.

6m WSPR at a quiet time
Path G3XBM-G4IKZ 6m |
After a brief outing on 40m I have QSYed to 6m WSPR in the hope of getting a few European spots by wintertime Es or even some tropo. In the last few hours my 2W has only reached G4IKZ who is 18km west of me. Signal reports are (expectedly) consistent within +/-2dB but I'm not sure if Nick is using a vertical antenna (like my V2000) or a horizontal beam. This evening I spotted G8EPA at 61km. Judging by how poor my report was compared with G4IKZ, I think we must be cross-polarised.

40m WSPR - instant success to Australia
Keeping at 1W from the FT817 into the Par end-fed I got instantly spotted in Australia at over 17200km this early evening. WSPR really is amazing. Reports from VK now both on 40m and 20m with the low wire antenna. Lots of other spots followed. More spots from VK7BO followed. Nearest station was G4IKZ just 18km away.
First 40m WSPR results with 1W to my Par end-fed |
20m WSPR - too easy
Late this afternoon I have been on 20m WSPR with 1W RF to my compact Par end-fed antenna. Best received signal was from the USA west coast but all the reports of my signals, so far, have been from this side of the pond.
Really 20m is too easy on WSPR at this level of QRP power. I should be running 50mW or less.

Home at last
This morning, Jan 3rd, I was discharged from hospital after 3.5 months due to to a bleed on the brain.I am far from well still and have lots of work (exercises) to do to to regain my health, which I hope to do in the coming months. I know it will be a hard slog.
My 2W 10m WSPR session over New Year was very successful with plenty of USA spots in the log. I hope to get back in the shack again soon.

Logging into a Windows PC and 10m WSPR
When I came to log in on my old (lab) Windows XP PC today it was a nightmare. Firstly it had not been used for almost 4 months and refused to bring up the log-in page. Then I'd forgotten my log-in details: even my old hint did not help. In the end after many attempts all was sorted but what a struggle with my poor addled brain currently. I've even made a small start on the tax return online. At the moment I am making lots of typos on the PC and everything takes twice as long as it did.
I've started WSPRing on 10m for the first time since September! My old life is slowly returning, thank God. Not bad reports too.

Release Date
The latest news from Addenbrooke's Hospital is I should be home for good by Jan 6th. After that, apart from continuing to get better, I hope to buy a new rig and do my on-line tax return! Expect blogging proper again within a week or so. I continue to slowly improve on all fronts but find I am making lots of errors typing on the PC still.
Currently on 2 days' home leave over New Year (1 night at home) but have to return to hospital by 5pm Wednesday.

IC7100 from Icom
When it comes to new 100W HF rigs the new IC7100 looks to be relatively good value at just under £1300 in the UK. This includes 4m and 70 cm coverage and DSTAR. I am a little skeptical about the clarity of the LCD touchscreen display. Other good rigs don't cover 4m or bands above 6m.I am still tempted when I get " released" from my hospital prison. My heart is still in QRP but the Elecraft KX3 is a similar price with just 8-10W,fewer bands and arguably less well suited to base station digital use. We'll have to see when I get out of my hospital "prison". I may just buy a second FT817 and another auto ATU.

Books
The last few weeks has seen me devouring a number of novels to kill the monotony of being in hospital still. Latest estimates are mid January for going home ,when I hope to be able to swallow some soft foods. Books read include:
"Oranges are not the only fruit" by Janice Winterton
"Night Fire" by Ken Follett
"Eye of the Needle "
"The Girl with the Dragon Tattoo " by Stieg Larsson
At the moment it takes about 3 days for a 560 page book. I am REALLY looking forward to going home when the ham radio blogging can resume.
Interestingly, I have read very few amateur radio books apart from 1 QST and a few RadComs and PWs. So far I have had visits from around 45 people including a few local hams. My brother has raised over £1000 for the charity "Headway" as a result of my bleed on the brain.
