Jamming on PSK
I was on 15m PSK31 and in the process of calling PY3ED when a vicious jamming signal started up.
![]() |
| Jamming on 21MHz |
As you can see, it did a good job of obliterating all signals. It seemed to be centered around 21.070MHz and extended for 50kHz or so in either direction.
I don’t know how long it stayed on for because it was lunch time so I went to have something to eat. When I came back the interfering signal had gone.
Was it something local to me or has anyone else seen it?

From attic to attic
Thanks to some excellent support from JT-Alert’s author, Laurie VK3AMA, I now have my alerts fully working and have gone back to JT65A with renewed vigour. I was getting a bit frustrated as many DX stations that I could decode clearly were not returning my calls. Is there something wrong with my setup? Perhaps it was just because it was the weekend and busier than usual so that others whom I couldn’t hear were replying to the same call and the DX couldn’t decode any of us. A few times the station I called replied to someone else.
I still managed to work several DX stations on 10m and 15m using 30 watts of power. Best contact of the day was with KC2WUF who said that he was running 3 watts to an attic dipole. (Actually he sent “3W ATIC DP” but I got the message!) It’s a pity I wasn’t running QRP this end as it would have been good to have a 2-way QRP QSO attic to attic!

Where does the money come from???
For some time now there has been a rumour of a new radio coming out from Kenwood.
In Japan Kenwood is anouning a new addition to the family of radios. They are saying the TS990S will be released Feb 2013. It's a great radio with many features and great specs...but it comes with a very steep price tag.....9,138.78. I am just not sure how folks come up with the cash for rigs like this.

More on programming the Baofeng UV-5RA
After seeing my post about the fun and games with the UV-5RA yesterday, Steve G1KQH kindly dropped me a note to say that there are two versions of the UV-5 software. One of these can be used with the UV-5R and one which may be used with the newer models.
These may both be downloaded from the Sinotel site, along with many other utilities
Thanks, Steve!
