2 x LFA five element 6m yagis (pictured right on Versatower).  Made by GØKSC of  Innovative Antennas, 4.4m one piece boom, with matching coax lines to a power splitter - but some of the elements are missing.  I have some aluminium tubing that the missing elements can be replaced with.

 

 

 

 

 

 

 

Array Solutions Mini StackMatch II, brand new and un used.  Two antenna port StackMatch without relays with SO-239 connectors.  Handles 3kW.  Array Solutions product code: Mini SM2 3K-SO.
This device is basically the StackMatch without the ability to do any switching of antennas.  It is a fixed transformer device in a die-cast aluminum weather resistant case.  It will provide phasing to two or three 50 ohm antennas without the ability to switch the stack like the standard StackMatch product.  They can be combined to allow stacks of 2, 5, 6, 8 and 9 antennas.  It has the same specifications as the standard StackMatch and can be used on 6 meters.

Antenna builders - I have a large quantity of aluminium tubing, some new and some from various antenna projects, including some 15 and 10m traps that I used to make my own for three and four element trap beams for 20, 15 and 10m.  I also have a large collection of fixings, clamps, boom to mast plates, etc thatv I have accumulated over the years and do not now have a use for.

 

Scaffold joiner.  Used for joining two sections of scaffold poles or other 2 inch OD aluminium tubing, for a mast.

 

Included amongst the aluminium tubing is 70 feet (3 x 20 feet and 1 x 10 feet sections) of three inch diameter tubing, that was used as the boom on a Wilson full-size six element yagi for 20m.  I never put it up but bought the antenna for the elements that I used as the basis for my own trap beams. 

 

Accessories

 

 

Ameritron QSK-5 2.5kW Transmit/Receive Switch.  Allows use of a linear amplifier for high power QSK CW, for packet, AMTOR, and any mode requiring extremely fast switching between transmit and receive.   Uses electronic PIN diode switching to give lightning-fast QSK operation from nearly any HF linear amplifier.

Dummy Load.  Power about 100W, size 6½ ins long by ¾ ins OD (16.3 cms long by 2 cms OD)

 

 

Elecraft PR6 6m receive preamplifier (with manual).  The PR6 is a high-performance, low-noise 6m preamp that can be used with the Elecraft K3 or other transceuivers.  It is especially well suited to the K3, which has exceptional dynamic range, yet can benefit from additional gain for 6m weak signal work.  Adding the PR6 typically improves 6m MDS from about -136 to -143 dBm.  The noise figure of the preamp itself is typically 0.5dB.

 

Elecraft DL1 Wideband Dummy Load (with manual).  A general purpose wideband 50 ohms dummy load that can be used with an Elecraft or other manufacturer’s tranceiver for test purposes.  The DL1 also includes a diode detector that can be used to measure power output, calculated from a chart in the manual.  Power rating: 20 watts maximum.

 

Elecraft K3 12VDC current mod kit K312MDKT, new with manual (not pictured)

 

Heathkit HD-1422-A RF Noise Bridge, with pdf manual.  A useful tool for the amateur or SWL who demands maximum performance from his antenna system.  An SWR bridge tells you how well an antenna is matched to your station transmitter, but the antenna noise bridge tells you what is causing any mismatch.

Vintage Radio

 

Valve PM12M, new and in original box.  The PM12M is a screened pentode for RF amplification. It is one of the early valves made with the anode as top cap connection, later types placed the control grid connection to the top cap for even greater separation of input and output circuits.  The PM12V variable μ pentode was released in 1932 and was replaced by the PM12M in 1933.  Equivalent to the VR41, CV1041, K5ON, W21Met, 210VPA, 210VPT, VP210, VP2, VS210, VS2, 220VS, S215VM and 218VSG.  Was popular in the days (1970s) when the RSGB’s National Field Day restricted transmitters to one valve with a maximum of 10W.

 

 

Roberts R 200 portable transistor radio, serial V 55419, manufactured 1960-64 by Roberts Radio Co Ltd, East Molesey, Surrey.  Superheterodyne (common); ZF/IF 470Hz.  Medium and long wave-bands.  Powered by 9V PP9 battery (not supplied).  External antenna socket on rear.   Originally priced at £14 in first year of manufacturer.  Very good condition for its age with nothing broken (except the carry strap, see picture) and no scratches or marks on the case.  Radio works fine on the long-wave band, especially with an external aerial, but there is a fault on the medium wave-band in that stations are only received when I lightly touch part of the tuning condenser.

Amateur Radio Sale

 

26 October 2020

 

After 47 years of being a hoarder and building up a large store of amateur radio equipment and book, sadly I have reached the stage of life where we have to down-size to a smaller house with less land where I will not be able to make use of, or have the room to store, much of my equipment or books.  I am therefore offering it for sale before, perhaps, donating it to a club, or even scrapping it.

 

I have a large amount of other amateur radio equipment, that is too numerous to list separately, and which will be made available to personal callers.

 

I haven’t priced each item because I haven’t had the time to research what each item couldm be  worth etc, but if you let me know anything you are interested in, then I will send you a postage / shipping cost, and I am sure we can come to an agreement on the price.  Most of the equipment can be sold cheaply as I just wish to dispose of it.

 

Please email me at <chris@g4bue.com> if you would like more information about something or would like to visit and look at what I have.  I am retired and am generally available most of the time.

 

I am regularly adding new items, so please look back from time to time.  I will delete items as I sell them.
