HF Mobile 60 Amp Power Source

-

The Toyota mobile Ham station has been working amazingly well since I knocked up the roof-bar mounted stainless steel antenna brackets. The reports and results that I've received have made me realize the benefits of running 50W /mobile into 3 meters of 50 ohm low loss coax. A nice and simple set up with low losses with a well grounded rig/antenna to the vehicle chassis combined with a modest antenna is a very effective way to put out a good signal, as I have been finding out over the past 6 years.

With the Yaesu FT100 set at 50W I can operate continuously when the vehicle engine is running, but the Toyota 2.0 Litre Petrol 4X4 needs a 45AH battery to power its creature comforts, which get a bit of a hammering during these wintry months.
So, I decided to replace the battery with something that would give me a bit more Umph, for both the Toyota and the amateur radio equipment carried on board.
I picked up a heavy duty replacement 65AH battery, which will give me a few extra amps for a lot longer. The mobile station is now at 100%, firing on all four cylinders! Listen out for 2E0HTS/M somewhere on 20M. Have a nice weekend.

Hi Simon,

I've just installed a Ft-857D in my car, and i'm waiting for 20m Diamond mobile antenna.
I hope we could have a qso soon.

Hi Cyril,

nice to hear from you! G L with your new mobile set up, it sounds cool.
I look forward to many QSO.

Have a Happy Christmas to you and your Family!

Many DX 73

Thanks Simon, and merry christmas to you, Louise, and Dudley of course! :)


I'll try to send you some hours and freqs to manage a HF rendez-vous when my setup will be ready.

Best regards,
Cyril

Full Size Delta Loop for 20M

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

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

New DX Contact 0n 12 Meters

Today I managed a nice QSO with Tom ZD7X who is located at St. Helena which is quite a distance away from my location. I managed to work Tom ZD7X with a 5/9 report operating my FT-767GX with my home brew 20m delta loop assisted with the MFJ-969 to tune the antenna with 50 watts on 12 meters. 12M is rarely open and I have only had a few QSOs on this band so I guess the new Cycle has begun at last! Good DX de 2E0HTS 73
