eHam review 4.5 out of 5 stars: <https://www.eham.net/reviews/view-product?id=247>
N8LP Steppir Tuning Relay. Placed in the power lead between the SteppIR PSU and the SteppIR controller, it detects when a Steppir antenna is actively tuning and blocks an amplifier from inadvertantly operating until tuning is complete, thus preventing transmission of high power into the Steppir elements while tuning.
For details, see: <http://www.telepostinc.com/STR.html>
Tennadyne Slipp-Nott (not pictured). Model HD version for Steppir antennas. Clamp mechanism that fits as part of the boom to mast clamp and prevents antenna slipping and turning in high winds.

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.
Boomless Quad spider for making an HF bands two-element cubical quad antenna (with the eight fibreglass poles below).
Co-axial Cable, BICC 2001 HCA 1292, 75 ohms (drum, approx 6000 feet)
Co-axial Hard-line, half-inch, two lengths, each about 60 feet. Was used once for a few days at an exhibition and has since been in storage. I am currently using a much longer length, probably close to 200 feet, that goes to my smaller tower, and which
will be available when I take that tower down shortly.
8 x Gemquad fibreglass (tridetic) spreaders,
one slightly damaged at base.
8 x Quad fibreglass poles (one slightly damaged),
each 19ft 8 ins long, 1½ ins OD and 3mm wall.
Hygain Tail Twister rotator and T2X 240V AC control unit, with manual. Not used since refurbished by W4QM, in Cocoa Beach, Florida. Dale had a very good reputation in Florida for refurbishing Hygain rotators and control boxes. I brought it home from the USA and it has been in storage not used since.
Ameritron RCS-12 automatic antenna switch (new boxed, manual but no control unit). Switches up to eight different antennas with the appropriate Ameritron relay box or any relays using up to 30V DC.
K9AY AYL-2R relay unit and AYL-2C loop control box (with manuel). Used with the K9AY two-way loop system described in the September 1997 edition of the ARRL’s QST magazine, The K9AY Terminated Loop - A Compact, Directional Receiving Antenna. The system provides a cardioid directional pattern in two directions.
Reace UH-74 Transceiver Tester (SWR bridge) for 50-430MHz

CB30A CB Antenna Matcher 100W
Telex Hygain Centre Insulator for multi-band doublets, moulded from high impact cycolac, stainless steel hardware, accepts ¼ or 3/8 inch coax.
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.
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.
eHam Review 3.9* out of 4*. see <https://www.eham.net/reviews/view-product?id=2239>
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.
See review at <http://www.w6ze.org/Heathkit/Heathkit_042_HD1422A.pdf>
Microphone, Icom IC-HM19 noise cancelling dynamic preamp microphone.
Microphone, Yaesu MH-1 B8, incorporated press-to-talk switch, incorporated up, down and fast tune control.

MFJ-484C Grandmaster Memory Keyer (with manual). Speed control (8 - 50WPM), weight control, tone control, volume control, delay control and 12 recordable memory messages.
Palomar Engineers Transceiver Preamplifier, can be added to most transceivers
in the frequency range 1.8 to 54MHz. It improves the gain, noise figure, spurious
signal and image rejection of the receiver section. The preamplifier is inserted
between the antenna and the antenna input of the transceiver and tha maximum
power that can run through it is 350 watts peak.
SPE 1K-FA carry case, but will suit other similar sized equipment,

Unified Micro Systems (USA) BCD-10 Band Decoder / Antenna Selector kit, new unused with manual (not pictured)
Unified Micro Systems (USA) HSD-9 High Side Driver Board kit (for use with BCD-10 above), new unused with manual (not pictured). The HSD-9 High Side Driver board is the easy way to adapt a BCD-10 or other low side switching band decoder to a high side antenna or filter switch.
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.

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 <email@example.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.
