.: Station Equipment

Radio W7VO Sign

The station is currently equipped with three separate operating positions, spanning two rooms. Two of the positions are primarily for contests (equipped for either single op, muti-single, or multi-two), and the third is the "boatanchor" station.

W7VO Contest

Typical Contest Configuration:  Dave, WZ8T, is on the left at Operating Position #1, Bob, W7CO, is on he right at Operating Position #2, and Dave, W7CAR is patiently waiting his turn at the microphone!

 

Operating Position 1

 

Operating Position #1 consists of a Yaesu FT-2000  mated with an Ameritron AL-1500 amplifier.

This station has great noise mitigation for the lowbands, so there is a JPS ANC-4 Noise Canceller, which uses either a HyGain 14-AVQ vertical, or a very steep inverted vee off the main tower for special "noise antennas". There is also an Ameco PT-3 Preamplifier, used on 80m and 160m with the Beverage receive antennas. The yellow box marked W7VO controls the direction of the Beverage antennas (N or S), and switches between the use of the SP-2000 speaker or headphones. We have added  the "-RA" modification  to the Ameco preamp,
(Page 1) (Page 2) which adds a second switched Rx antenna input to the unit.

The FT-2000 is an interesting radio, certainly one of the most complex piece of ham gear I have ever seen. There are exacly 100 knobs and buttons on the front panel! I have made one minor modification to mine to keep the transmitter from getting into the RX ant port and damaging components. This is shown on my FT-2000 page, and I am sure there are more to come. 

The antenna tuner is a vintage RF Components Maxi-Tuner, modified with a pair of vacuum relays that enable the tuner to be bypassed when not needed. The bandwidth of the TH6 is somewhat narrow, and this tuner primarily used when we run in the CW portions of the bands.


 


 

 

Station 2

 

Operating Position # 2 consists of a Yaesu FT-1000D with the matching SP-5 speaker feeding an Amp Supply LK-500ZC amplifier. I have added the Inrad roofing filter to the FT-1000D, along with the W8JI noise blanker and key click mods. These are mandatory mods if you use a FT-1000 in a contest environment! For voice keying a MFJ-434B is used. There is also an Ameritron ATR-30 tuner.  This station is mostly used as a multiplier station for multi-single operation.

 

Both stations are equipped for single op, multi-single, or multi 2 operation. For antenna switching between the stations there is a WX0B  antenna switch (6 antennas into either of 2 radios), and a separate Ameritron RC-4 switch which controls the 4 sloper antennas.

We run the N1MM+ software package, using a pair of Dell Optiplex dual core computers running Windows 10. They are networked together, so logs are shared. There is also a third computer (not shown), on a desk in another office room that is also networked to these two for a "mult hunter" computer. (Can carefully hunt the spotting networks for new mults, then report them to the radio stations.

We also use a Heil Pro headsets with the HC-4 mic elements, For CW, there is a choice of a Bencher BY-1 key, or a Vibroplex Vibrokeyer, tied to a pair of K1EL Winkeyers.

 


 

 

 

Station 3 

 

Operating Position #3 is our "vintage" operating position, with two sets of equipment, spanning two important generations of ham radio, postwar, and the late 60s-early 70's.

Along the top is our postwar era CW/AM station. It consists of a Hammarlund HQ-120X (1939 vintage) receiver, and a choice of a very rare John Meck Industries T60-1 (1946 vintage, less than 200 built) transmitter (pair of 6L6s), or a Harvey Wells Bandmaster TBS-50C/D (1950 vintage). The external power supply (APS-50) for the Harvey Wells is on the second shelf. To complete the experience is a set of WWII era headphones and a J-38 straight key. Frequency control is via a supply of FT-243 crystals. This equipment is not fully operational yet, but will be soon.

The bottom row comprises a Drake C Line (all 1973 vintage), consisting of a Sherwood modified R-4C, TX-4C, MC-4/AC-4, and MN-2000 tuner, followed by a Heathkit SB-200 amplifier upgraded with all the Harbaugh goodies. The microphone is a Shure 444 .
