My new radio is a FT-100d and a VECTRONICS VC300DLP tuner the ICOM 746 has to go :( car needs taxing and MOT is next month:(( Still at least I've still got the VX-170,the 7800, and the 100D left :)) catch you on the air on HF now I can put a wire up and tune it ;) 73 de M1PAC
Well I saw one for sale at the rally @ York and that was going for £550.LAM has a used one for £599. To YOU £550 with SM-20 mike & the UT-102 speech pack ,to anyone else £575 Boxed manual fist mike.
I put a wire up,tunes it OK will be on PSK tomorrow (weds) and SSTV from about 10am onwards also have a EeePC that I am about to put XP on so I can use that ;) hope to hear you soon.I have the 7800 on scan most times so if you give me a shout on GB3TP, GB3XL, or 145.500 it will stop
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...
This Antenna design was one that I used about 4 years ago, it worked exceptionally well on 80m and 40m. The size of the antenna makes a Half wave length on 80 meters, and with the traps a half wave on 40m with a SWR (standing wave ratio) of 1:1-1.5 across both bands. It worked well also on 20m with the use of an A.T.U (antenna tuning unit). I made my version of this antenna using 3mm multi strand copper cable which I left covered by the PVC insulation. The traps can either be home brewed using some 40mm diameter plastic drain pipe and winding wire around the pipe approximately 10 turns, then connected in line after the 10 metre lengths. Or the alternative is to purchase some commercially made 7.1 MHz traps, and fit them in line the same way. The antenna can be fed with 50 ohm coax with a home brew balan or again a commercially purchased balan. The wire lengths of the dipole are 2x 10 metres and 2x 6.7 metres as shown on the diagram above. This antenna can be mounted quite low to the gr...
After 10 years of careful use my G-5500 eventually developed a couple of faults on the elevation rotator side. Fault 1. For the past year I have had to guess the elevation as the readout was no longer working on the controller unit. I suspected the position switch which was located inside the rotator up above the house roof which was a pain in the butt to say the least. Fault 2. Over the winter the gearbox on the elevation rotor seized up solid. I plucked up some courage and erected my ladder and which with the aid of a rope to lower the mast it all worked out quite straight forward. Once down out with the impact driver and away I went. Once I split the case with the impact driver which was easy, I found lots of sandy grit and dried out remains of what should have or once was gearbox/bearing grease. The next step was to inspect the seized gearbox and then remove the main shaft which can only be carried out by first removing the entire gear housing u...

Have a good holiday both of ya
My new radio is a FT-100d and a VECTRONICS VC300DLP tuner
the ICOM 746 has to go :( car needs taxing and MOT is next month:((
Still at least I've still got the VX-170,the 7800, and the 100D left :)) catch you on the air on HF now I can put a wire up and tune it ;)

AHH You got a proper Rig Now (Ft100D). lol
The tuner sounds impressive, let me know how much the 747 is going for? You never Know?
Still havent heard M1PAC for quite a while, however Jeff G0GNU told me he heard you at the rally call in after the GB2RS News.
Catch up soon, best 73
Si
