29MHz FM

Just after 7pm tonight (Friday) I hope to do some tests with G4NUA in Cambridge around 29.6MHz FM. We will both be HORIZONTALLY polarised (Homebase-10 wire halos) running around 10W FM. If there are others in the mid-Anglia area who would like to join us then please do call in.

At one time there was a lot of activity on 29MHz FM but there is much less these days or is it just around here?

1930hrs update: successfully heard G4NUA at RS56 but he could only just detect my FM carrier (no modulation) his end. Surprised that we were unable to work each other at this distance with a pair of horizontal halos. On 2m he was 59++ and on 70cms 56. Ted was using the FT8900 4 band 50/35W FM rig covering 10m, 6m, 2m and 70cms - nice radio.

Useful on-line distance calculator

http://copaseticflow.blogspot.com/2008/12/new-qsl-mapper.html

Type in the 2 callsigns to get the QSL addresses and the distance, (in miles or kilometers), between them plus miles/watt. Thanks to KD0FNR for finding this one.

The distance of my 2007 6m QRP QSO with K1TOL works out at 5083kms.

UK price rises - Yaesu and Icom rigs

Have you noticed that prices of the Yaesu FT817 and Icom IC703 have been significantly increased by at least one of the big UK suppliers in the last few days?

With the falling pound I can understand margins being squeezed more than before but surely, with a VAT reduction and with Christmas coming, this must be the most stupid piece of marketing yet.

Later comment: Several people have explained to me that the yen/pound exchange has significantly worsened so there is probably little the dealers could do but pass on a major part of their price increase on goods from Japan. I also see that most dealers are now holding the old prices on goods in stock as well as offering some good trade-in deals.

SM6BHZ on 504.5kHz - strong

The 3W ERP beacon of SM6BHZ on 504.5kHz is coming in well tonight at 2215z in slow CW and QRSS3. QSB rate is slow with peak to trough being around 1 minute with me.

Ham gear for sale (silent key G4IRZ)

Recently I have been asked to help sell a large amount of ham radio equipment from an ex Royal Signals ham who is now a silent key - Len Winnart G4IRZ. This includes a FT767DX (base mains powered multi-mode rig), a DX70 multi-mode HF/6m transceiver still in its packing, FP707 PSU, a GDO, various ATUs and SWR bridges and lots more. If anyone is interested in seeing the list please email me at rogerlapthorn (at) gmail.com and I will send you the full list of items.

In particular, if anyone is prepared to make an reasonable offer for the whole lot I'd be happy to discuss. All I am trying to do is dispose of the equipment to someone who would make use of it at a fair price for his XYL.

Please contact me ASAP if you have an interest in this kit.

Argo plot of OK0EMW tonight on 505kHz

This is the Argo waterfall plot showing the Czech 505kHz beacon OK0EMW on QRSS3 (slow CW, 3 sec dots) coming in well tonight at 1700z. It was not audible by ear though. Note the QSB in the middle when the number 0 was being sent.

VO-52 satellite reception

Not listened for amateur satellites for some time so took a quick listen on 2m SSB around 145.9 this evening. Managed to catch a couple of VO-52 satellite passes and logged IK1SOW, EB2FJN, SP4BY and HB9XJ on SSB. I have printed out the passes for the next few days so will see what else I can receive on the FT817 and the vertical colinear antenna.

The first place to check for first-time satellite SWLs is the AMSAT page which has lots of helpful info on satellites, frequencies and passes.

WSPR beacons on the 500kHz band

There are now some stations appearing on the 500kHz band using WSPR mode which is a clever digital beaconing system allowing reception to be monitored and mapped/listed using PC software attached to a suitable transceiver and the internet. In effect you can set a transmitter running then check for reception reports from similarly equipped stations via an internet reporting page. See http://www.physics.princeton.edu/pulsar/K1JT/ for more information. K1JT designs some mighty impressive ham software! When I get a WindowsXP machine that is reliable again I will try this mode I think.

A family picture

One of our greatest joys this past year has been our first grandson.  He is now 1 year old and looking more like a little boy every day that passes. His mum is French and his dad Tim is English, so he is likely to grow up speaking both languages. This is a nice picture of my wife Lis, our elder son Tim and little grandson taken a few days ago. Our other son and his Australian wife are expecting their first grandchild next March. Whether either will be interested in ham radio remains to be seen.
