Pure Fun playing Ham Radio

Greetings once again, I've been playing radio quite a lot since I repaired the ft-100 /mobile rig, making many successful DX and local QSOs on 40m, 20m and 2m. The next stage of improvement for my mobile station is to fit the heil base mic that I recently acquired from Ron 2E0DOG. This should be an easier way to operate hands free as well as maintaining top quality audio. I tried a hands free kit from Watson last year but the quality of audio was poor, so I've been using the standard fist mic from Yaesu ever since. I shall fabricate a bracket to mount the mic in the Toyota at the side of the steering wheel close to the dash. The mic has a separate PTT switch that will fit at the side of the hand break. I am awaiting a mic lead which will convert the round pin plug to the ft-100 mod type plug this should hopefully be arriving soon allowing me to begin operating the new set up. The other equipment has also been working well, especially the old ft-767gx which I have been running

50th Jamboree On The Air

Today has been a good day for Bradford North scouts, Bradford South scouts, Windhill Shipley scouts and Keighley Scouts who have all been active on the bands with the club station call sign MX0KSC. During the event the scouts got a chance to learn about Morse code, Q-codes, phonetics, International pre-fixes and call signs, as well as speaking world wide on amateur radio, also logging and e-qsl/qsling. All of the scouts sucessfully completed a range of tasks enabling them to obtain a scouting radio communicator badge. They were all extremely happy with thier achievements. The JOTA event is running all weekend and as it is celebrating 50 years of activity on Ham radio you can imagine all of the bands are extremely active with this celebration for jota. We spoke with 20 different Stations and all scouts spoke with each operator so if you multiply 40 scouts with 20 QSOs we had a total of 800 exchanges of voice contacts and greetings messages, not bad for 7 hrs of operation. Thanks to

Full Size Delta Loop for 20M

Image
I came across a simple delta loop design courtesy of dxzone found on the net some time ago and have been planning to give it a go for a while. This weekend I had a couple of hours spare, so I decided to give it a go using some 2mm multi strand wire cable, a dipole centre and a mixture of 75 ohm and 50 ohm coaxial cable. The delta loop is supposed to be resonant on 20 meters but I found it to be a little high so at present I am tuning the Loop with my mfj-969 which copes extremely well. The resonant frequency is 13.2 MHz at the moment so the next chance I get, I shall shorten the overall length making sure that each of the three sides are still equal in length, and hopefully adjusting the antenna for maximum performance ATU free for 14.2 MHz. I believe the miscalculation in the resonant length is probably down to the fact that my wire is covered in the plastic sleeving from the manufacturer which always effects the swr as I have noticed in past experiments with dipoles you always get

50 Years of Space

As most of you know its been 50 years since the historic launch of Sputnik. This link will take you to an interesting artical on Sputnik at the ARRL website. http://www.arrl.org/news/features/2007/09/28/03/ Its well worth a read if you havent seen it 73 all the best.
