Welcome. I passed my Foundation exam and got the callsign M3UKD on 4th Jan 2007. After operating as a Foundation Licencee for six months, I then took the Intermediate exam and passed in June 2007, and got the call 2EØUKD. I then took the advanced exam on 10th December 2007, and got the results on the 21st. Fortunately, I passed, and got the callsign MØUKD on 21st December 2007. I run an Icom IC-7400 from home, on 2m, and HF. Antennas are a Diamond X-300 mounted about 11 metres above ground for VHF/UHF, and a homemade carolina windom outside on HF. I also run 2 metres mobile with a Yaesu FT-2200, and portable with a Yaesu VX-7R, IC-706MKIIG or an FT-817ND. Thanks for visiting! John.

Hi,M0UKD
how long ferrite rod to built line isolator
for windom antenna.I have 1/2inchi ferrite rod.

73'

John M0UKD Wednesday, 5 May 2010 12:00
Hi Azmi.

Any length rod will work fine as long as you can fit your wire around it. RG58 is fine.

Good luck with it!

Regards, John.

Hi John. By googling I found your web page Time_Sync_Interval_Change_Vista_XP.pdf. It was very useful as I have an HP system with clock that loses anywhere from 2 seconds to 15 seconds per hour!! I have just set it to sync every 12 minutes, and will see how that goes. Many thanks! ..Bill.. P.S.: I am not a radio operator but I spent many happy hours as a teenager listening to various shortwave signals.
