Modern equipment in the shack

Other items for the shack, including BoatAnchors

Recent additions to the shack are an Icom IC-245 with its add-on SSB adaptor and a Ranger RCI-2950. These were both purchased at the 2015 AHARS Buy and Sell. Although it was sold as a 10M rig, the Ranger was obviously built with CB Radio pirates in mind. There are three jumpers inside that will configure it to cover the old 27MHz band and it will display the freqency or the channel number. These jumpers will also extend it's frequency coverage from 26MHz to 32MHz !

Antennas in use or under development

I have built copper J Pole antenna for 6M, 2M and 70cM and bought a G5RV from the USA for the HF bands. Very nice kit of parts, not worth me rummaging round for the various cables and fittings for the price. I also have a TET-Emtron TEV-4 four band HF vertical up in the air and I have replaced the 2M J-Pole with a RingO. I recently erected a second tower on the block next door and this has four antenna on top including a Tet-Emtron TE-33 three band beam for HF and I may buy the WARC band addition for this. This tower has a Yaesu G-2800DXC rotator fitted.

A collection of various SWR and RF power meters from a long time ago

Recently I was given a Trio PF-810 and it was very grubby and had U/S scribbled on the top. It has a fault and I cannot find a complete circuit diagram anywhere on the web, only a block diagram of how the smart bits of it works.

Antenna Test Gear

Having all this equiment to play with and experimenting with Antennas, I needed something to test them. The VK5JST Aerial Analyser is fine for HF but I needed something that would work on 6M and 2M. With this in mind raided the piggy bank and bought an mRS miniVNA and what an amazing little device that is.

Early in 2012 I did an ebay search looking for "Digital SWR/Power Meter" and found an item that had only been released in Hong Kong a week or two before. The REDOT model 1050A digital meter from Bejing SW-Tech Development Co Ltd (www.SW-tech.com).

This is a VHF/UHF meter Covering 100 to 150MHz and 420 to 460MHz and can handle 120 Watt. Do an Ebay search for REDOT SWR and you will find several merchants offering them for sale at about US$50.00. I purchased one of these but I was still looking for an HF version and sure enough about a week later I found the 2016A version from another Ebay merchant and this covers from 1.6 to 60 MHz and can handle 200 Watt. The VHF/UHF version displays in rotation forward power, reverse power and SWR and the HF version shows forward power, peak power and then SWR.

In addition to the miniVNA I now have an instrument from Autek Research a Model VA1 Vector RX Antenna Analyser. This has the advantage over the miniVNA in that it does not require a computer to be used but it only covers to 32 MHz. The VA1 manual and notes on its use.

The photos above show a simple "sniffer" Frequency Counter YAEGE FC-1 with a frequency coverage of 10Hz to 100 MHz and 50 MHz to 2.6 GHz in two ranges and an Emtron ENB-2 Noise Bridge. A review of this instrument from September 1993 Silicon Chip magazine.
