Ham Radio Deluxe is structured so that it can support most HF / VHF / UHF amateur radio transceivers and receivers. It currently supports ICOM, Yaesu, Elecraft, FlexRadio, Ten-Tec and Kenwood.
Key Benefits
- Built-in logbook,
- Favourites (just like Internet Explorer),
- Integrated DX cluster,
- Customisable band layouts,
- Satellite tracking interface,
- Scanning,
- PSK31
- Mapper
- Synchronise up to ten instances of HRD - tune one radio, the rest follow!
By connecting a cable between a PC to the transceiver you can controll the radio from the computer which brings the radio alive with this powerfull tool. I have been using the software with a FT817 and found it a joy to use. This program is free to Amateurs and is an intergrated system for most of the applications used by Amateur Radio Stations.
A simple 80 m antenna that works.
A simple NVIS 80 m antenna.
The problem - I was having trouble getting a signal out on 80m. The yard was to small for a dipole or inverted V and given the need to have a pole to hang it off. I had put up a non-resonant antenna with an open wire feeder. The antenna had 13.5 m of wire on each leg. The antenna was 12 m in overall length. (not enough wire in the sky). I started experimenting and added another wire which killed any performance it had. At a Christmas break up I got some good advice from Fred VK3JM. The next day the whole thing was pulled down and Fred advice was put into action.
The antenna system consisted of an Antenna Tuning Unit (ATM) feeding a long wire of 84 feet and a counterpoise of 90 feet. The ATU was mounted high in the shack. A suitable terminal was used to get the long wire outside. From there it ran through the shade area to a pole of 7 m in height. The remaining length of long wire ran back towards the house where it was tied off with some road for the last 4 m. The Counterpoise ran from the earth terminal on the ATU, outside dropped to the ground. The wire was laid on the surface of the ground and went to the back fence. A 90 degree turn and along the back fence to the corner of the property. Another 90 degree turn and the remaining wire was laid up the side fence.
The wire tuned up perfectly and good signal reports were received. Why does it work so well. It turns out to be an old design known as a W3EDP
At the November 05 Club monthly the guest speaker was VK3JP John Proctor. The subject of his talk was Digital Voice using a SSB on the HF bands.
