Day 5 February QSO Challenge

-
The QSO challenge for Day 5 was made on the 80M band at 20.11 utc where I worked DO1HEP - Hermann operating SSTV on 3.730 MHz. I was sending some slow scan CQ Calls when Hermann - DO1HEP received my signal and came back with some of his own slow scan TV images as seen below.


DO1HEP - Hermann was using Yaesu FT-897, 100W into a long wire antenna. I was using 25W from my FT-1000 with a RIGBlaster plus interface and Mmsstv software into my Windom antenna. I don't operate SSTV as much as I would like to and enjoyed making this QSO. Our stations are at a total distance of 515.6 miles apart, I am pleased with my completed challenge of the day. 73

Nice one Simon, I've been very active with SSTV on VHF 10 years ago. But on HF not too much. I've always thought about testing digital SSTV software some time. 73, Bas

Hi Bas, tnx for commenting I would like very much to make a SSTV qso with PE4BAS in the possible future. I have just made another nice SSTV QSO just now with DL6BBE and can already feel the bug biting hi hi. I am going to be listening down here (3.730) until bedtime and maybe again throughout the week. Take care and 73 to you and the family.

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...

Homebrew 40/80 Trap Dipole Design

-
Image
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...

YAESU G - 5500 Elevation Rotator Repair

-
Image
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...
