Hi, I am Tony I0JX
My radio station

 

My station consists of recent and vintage tube radios (old ham-radio, commercial and military sets).

 

MY RECENT RADIOS
 

Henry 4K-Ultra with a Bird Wattcher on its top,
connected to a Bird 4715 wattmeter

The 70-MHz home built amplifier (single 8875) is on its left

 

 

MY VINTAGE TUBE RADIOS

A friend of mine keeps buying vintage radio equipment and stocking them in a big room with no apparent criterion. More than an amateur radio station, that room looks like something in between an ham radio store and a surplus outlet!

It is not easy to turn a great deal of radio equipment into a nice station. In my opinion, to achieve that goal the station the following criteria must be observed:

ACCESSORIES

I have a selection of accessories some of which are used for my vintage radios. The remaining ones are for general radios wiring and testing:

 

MY HF ANTENNA

Picture below taken at https://maps.google.com/ shows the very place where my HF antenna is mounted. In the middle of photo you can clearly see my tower and the antenna aluminum tubes at its top. Coordinates are:

 

The Mosley PRO-67-C is a 7-element Yagi for 7 bands:

This is how it looks like (a 50-MHz 5-el Tonna Yagi has now been placed at the top of the mast)

The antenna, weighing some 55 Kg, is supported by a 15 m. tower placed on the roof-top of a 5-storey city building. A tram that rides up & down the tower allows you to raise & lower the antenna by simply turning a winch crank. Uncommonly, the tram does not wrap around the tower, but it instead slides on support guides fixed to one side of the tower. This design eliminates most problems with guy wires. That tower is produced in central Italy (contact I5JVA for details).

Though it clearly being a compromise, the antenna works acceptably on all bands. In particular, SWR is remarkably low; it never triggers the automatic power back-off circuit of my HF radios, except at the extremes of the 20-meter band.

This is the SWR response on 40 m.

and this is the 20 m. gain plot

(one step equals 14.4 dB)
