My postal address is not listed as I do not collect or send out QSLs for HF any more. I will reply to QSLs for VHF and UHF via the bureau.

Our new Yahoo group for discussions about the VHF and UHF bands is on -



This antenna used to be a 5 element Tonna for 6 m. Over the years the elements dropped off, starting with the driven element. It has now been removed and replaced with the antennas shown below.


The new antenna at the top is the Create CLP 5130-1 which is a log periodic covering 50 MHz to 1,300 MHz. Below it is a 3 element vertical beam for 2 m for local FM QSOs.


The birds have now found that they like my new antenna!

Other antennas include a Cushcraft R5 vertical for 10 m through to 20 m. There is also a trap dipole for 40, 80 and 160 m which is bent around the garden in order to fit it into the space available.

The main radios are an IC-756 Pro 2, for HF and 6 m, and an IC-910X for 2 m, 70 cms and 23 cms. I recently got back on 4 m where I am using a Spectrum transverter with an IC-703.

The photo at the top of this page was taken in my garden where this crapaud had decided that he liked life in my pond. Many people think of the cow as the symbol of Jersey but most of those of us who live here regard the crapaud, the local name for the toad, as the real symbol. There is even a statue of one in St Helier, our main town,-

Lunch at the Lighthouse Restaurant

This restaurant overlooks Corbiere Lighthouse which is in the south west corner of Jersey. We were there on Friday 14th of September 2012 when we had a nice lunch and an enjoyable chat.

On the other side of the table and at the left is Syd GJ0JSY. Next is Jean who is Lawrence's mother aged 92 and still enjoying joining in our lunches. Next to her is Mina M1AXI and MJ0SHI. On the right is Frank G(J)3WMR.


Installation of the CR-293 High Stability Crystal Oscillator in the IC-910X.

The radio has been working well on 2 m, 70 cms and 23 cms. The only problem so far has been some drift which was not bad on 2 m, significant on 70 cms and a bit too much on 23 cms.

I have now fitted the CR-293 option on 4th of April 2013. The instructions given in the manual and in the service manual were easy to follow although getting at the PLL board to remove the original crystal oscillator and fit the new one did take more time than anticipated. The hole in the screening plate was fine for adjusting the original crystal but I had to drill a new one for access to the trimming point on the CR-293.

This photo shows the CR-293 installed on the PLL board without the screening cover.


This photo shows the screening cover back on the PLL board. You can now see the extra hole I had to drill in order to get access to the trim point for the oscillator. It has to be large enough so that the plastic cover can be removed from the CR-293 for trimming and be replaced afterwards.
