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 o

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 all

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 sl

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.

FT-100 VFO Rotary Encoder replacement

For those of you that are regulars you will all know about the problems i have had in my mobile station over the last fortnight and for anyone who is here at ham radio for the first time,hello and welcome to my web blog. After operating all week from the mobile on the recently fitted ft-857 I was now missing my old friend the ft-100 which was suffering with a locked up solid vfo with no easy way to tune up or down. So I struggled all week on the ft-857 that seems to not be able to blank out the rfi from the engine too well but still made a couple of QSOs on 20m, 40m, and 2m asking for a audio reports. The Conclusion FT-857 vs FT-100 The Old ft-100 in this case is better than the new ft-857 on Receive, Audio quality,and overall performance on HF and FM. As for the ft-857, is easy to use and looks good but that's about it, as soon as the FT-100 gets back in its right full place the better. Well, Karl G1YPQ got it right when in qso he was telling me that I did not sound as clear as u

Update On New Radio In The Mobile

I managed some good reports today whilst driving too and from my works QTH. At about 7.15 utc I worked into the Azores on 40m from the ft-857 with 50watts into a maldol hfc40 mono band antenna. I was given a 5/6 report which was well received at 5/9, I then tuned to 20m and switched to the hfc 20, where I managed a 5/9 into Italy just as I was arriving at work. The best report of all came on my home bound journey at around 15.45 utc from Gary EW1MM on 14.174mhz who I have made QSO with many times from my mobile, my home station, and at the STAR Centre. Gary gave me a super critical report of sounding sharp and clear with a very occasional clip on the odd word.As soon as I was stationary I reduced the ssb mic gain down from 40 to 30. I will see how that setting works and hopefully it will be a true 5/9 if I can manage to refain from shouting into the mic, I have constant reminders from Louise that I can get quite loud when struglin to get through the QRM whilst in QSO. You no what its l

New Radio in My Mobile

I have worn out the VFO on the magnificent little ft-100 that has served me well in my mobile. The rig works fine apart from the actual vfo that has now locked up which makes it awkward tuning around the bands using the select knob and mic buttons instead of the vfo, and of course driving at the same time. After trying to operate this way for a couple of days, I soon decided to take the ft-100 out of the vehicle and exchange it for the ft-857 from the shack at my QTH. The ft-100 will be ok interfaced to the p.c where my mouse, keypad, and screen control my rig. I will send off at the same time to yaesu UK and hopefully obtain a replacement VFO which looks fairly simple to install. In the meantime I have been running the two rigs in reverse rolls, I am just about getting used to the changes in my mobile. I am not sure about the ft-857 on 20M or 40M as I have only had a couple of QSOs on each band so far, but apart from the electrical noise picked up from my Toyota Rav4 all is well. The
