In the Shack ~ The HF station

The shack contains a collector's radio station. These radios were top rated in the eighties. The station is well maintained and is working perfectly. It is still currently in use. If you are among these stations lucky enough to contact me, you will hear (for some of you with a bit of nostalgia perhaps ...) the "sounds of the eighties".
The picture below shows the F5VIF's amateur radio operating position with a point-and-see captions and so you will be able to get information about each of the devices.

Below : various changes and view of the shack when using phone transmission

The shack when using SSB

A high quality microphone offering a wide frequency response while keeping and reproducing with accuracy the articulation of the speech is used during phone operation. The Yaesu MD-1 microphone was selected for its exceptionnal audio characteristics giving a cristal clear modulation. In addition a W2IHY 8 bands equalizer is used to customize transmit audio for personnal taste.

The first picture above shows the transceivers connected to the analog FV-101Z external VFO. These VFO's were replaced by digital models (second picture above and pictures just below) in order to have a similar stability as more recent transceivers. Featuring PLL synthesis and digital memories, they may be tuned in a variety of combination using the main dial, memory bank or keypad. The FV-901DM has a 100Hz step and fine tune is done with the RX/TX clarifier. The FV-901DM is especially easy to use to store and recall frequency memories while the FV-101DM can scan the band in 10 Hz steps providing a smoother tuning. They both have 3-speed scanner and two-loop PLL circuit designed to produce a clean output signal for a spurious free receiver and transmitter.

The Aerial

The aerial currently in use is a telescopic quarter wave vertical antenna (MFJ-1979) which is fitted at a height of 20 meters above the ground. Due to its height and its surroundings the antenna does not need radials, instead of them a tunable counterpoise is installed. A coil (MFJ-67) is added when the antenna is used on 30 and 40 meters.

Vertical Antenna on balcony




This image slider shows a selection of the finest QSL cards received for contacts with rare DXpeditions or stations situated at a very long distance. These contacts were all achieved with the antenna shown above.


Jaw Mount




This picture shows the mast clamp "Jaw Mount" and the MFJ-1979 telescopic quarter wave antenna of five meters in length, both made of stainless steel. This is a great combination !

Radial
CLEAR=LEFT>



As it is seen in the opposite picture, a tunable counterpoise simply made with a metal tape measure has been added to tune perfectly the antenna. As the measuring tape is graduated the antenna is tuned very quickly on any band.

Balun



In order to achieve very high performance (among other advantages) a high quality 1:1 choke balun from "Balun Designs LLC" was also added to the antenna.

Balun


On the higher bands a 2:1 unun is added to provide impedance transformation and a perfect match to the transmitter. The unun is used jointly with the 1:1 choke balun. Due to the proximity of the walls and structure of the building the antenna specifications are modified. In this situation, the impedance of the antenna is determined by the position of the counterpoise which is connected at the base of the antenna. On the higher bands the tape measure counterpoise (radial) is slanted, on the other bands it is streched horizontally.

Coil MFJ-67



The MFJ-67 is an excellent air-wound Hi-Q loading coil (2 inches diameter by 6 inches length). This coil can handle 1 kW and is used on 40 and 30 meters with outstanding results. The 1:1 choke balun as well as the tunable counterpoise is also added to this antenna system.

Fritzel Coil


Sometimes another loading coil made by Fritzel is used. Enameled copper wire (#15 AWG) wound on a special polycarbonate chuck is part of this coil. The chuck contains a high voltage air capacitor and is held between two steatite discs. Attachment hardware is made of stainless steel. This coil can also handle easily 1 kW. Results seem very similar to the MFJ-67 coil. (Move the mouse over the opposite image to see a short animation)

MFJ 80m loading Coil



On 80 meters the MFJ 404-0009 coil is used to load and tune the MFJ-1979 telescopic whip. Only one third of the coil is used. Even with this short antenna, DX stations are easily worked.

VAA


VAA


An antenna analyzer was used to determine the correct position and length of the counterpoise. The impedance matching to the transmitter is nearly perfect on all bands from 40 meters to 10 meters. As a result an antenna tuner is not needed.

Preference

I like both telephony and telegraphy (CW) but I have a marked preference for CW. Since I am basically a CW operator I enjoy chasing rare or very long distance DX on the lower portions of the HF bands. The station is also often on the air during major contests and contributes mainly in giving points to other participants.

UR5CDX Key


This is the key I currently use. This beautiful piece of artwork is a dual lever iambic key designed by UR5CDX. This is the CT599MX model. Hand made, it has an exceptional quality chrome plating. It has also solid double silver contacts and my model has a unique brass plaque featuring my callsign. With a weight of 1.4 kg the key is very stable and does not move sideways when in use. The adjustements are easy and accurate. It is a must !

UR5CDX Eridan Key


This is the second key I currently use. This model is called Eridan MB and is the premium piece of artwork designed with soft classic lines by UR5CDX. It is made of 1.3 kg of brass and has an exceptional quality polish, mirror like smooth surface, quad balls bearings and solid double silver contacts. It has also a unique brass plaque featuring my callsign.
Exceptional model !

Vibroplex Key



Here is another key I also use. It is a iambic (dual-lever) paddles key, model "Presentation" manufactured by Vibroplex. It has jeweled movements and a polished decorative chrome base with bright chrome top parts and a 24K gold plated brass plate over it. The callsign of the station is also engraved on it. Top-notch key !

Vibroplex-Bug Key


This is the semi-automatic "Lightning Bug" Vibroplex key. First patented in 1904, it is a genuine piece of history. It is still manufactured today. This version was released late in the seventies by the Vibroplex Company and I used it intensely in the eighties. This key is now in my museum but I still use it from time to time just for the fun of it. When using the "Lightning Bug" I can have the same experience pioneer telegraph operators felt over a century ago ... yes really ...

Kenpro KP-200



This is the Kenpro KP-200 Memory Keyer. The iambic paddles key is included inside the housing. The accuracy and flexibility of its adjustments as well as the softness of its movements are very relaxing for the hand. Till now it is the best key I have ever used. I use it with the HF portable station.

Phone ~ Digital


RigBlaster


Here is the "RIGblaster Plus II USB". An easy to use interface between the computer and the transceiver. The RIGblaster was selected mainly because it has a 8 pin round microphone connector on the front panel and on the connection cable to the transceiver. As from time to time digital transmission is also used, switching between phone and digital modes can be done instantly without changing the audio control settings of the rig.

Micro MD-1


MD-1 Yaesu microphone. This microphone is designed for high quality audio characteristics. The large dynamic element provides an extremely wide range audio response (100Hz-15kHz(-6dB). It is fitted on an 8-point flexible suspension support system Heil "SM-1 shock mount". This system helps suppress low-frequency rumble on the microphone line by absorbing and damping vibrations picked up from the desk or console. The SM-1 shock mount is used with the Heil PL2T a unique and versatile high quality boom.

Pop filter


To eliminate 'popping' sounds caused by the mechanical impact of fast moving air on the microphone occuring particularly in the pronunciation of aspirated plosives, an anti-pop noise protection filter is added to the microphone. It also protects the microphone against saliva. Salts in human saliva are corrosive and thus it prolongs the life of the microphone and its specifications. But moreover it maintains all the time a minimum distance between the mouth of the operator and the microphone.

W2IHY 8 band audio equalizer



The W2IHY 8 Band Graphic Audio Equalizer and Noise Gate is a sophisticated unit loaded with high-performance features. It gives you the control of the transmit audio quality letting you customizing the audio just the way you want. The Noise Gate is a very useful solution for noisy operating environments.

W2IHY EQplus audio processing equipment


The W2IHY EQplus Parametric Equalizer adds another layer of features and functionality to the 8 band equalizer/noise gate, and that made it a must. Adding the W2IHY 8 Band Equalizer and the EQplus gives to your voice presence and a very distinctive audio. Depending on the settings you will get an unmatched full spectrum broadcast sound rich with bass and yet clear as a bell or a strong and crisp modulation to break through a pile up.

Wavenode WN-2d




Wavenode WN-2d high precision RF power meter. It uses the PC to automate the antenna's SWR and power measurements.

Spectr-Analyzer



Wavenode WN-2d Oscilloscope and Spectrum Analysis of the RF Modulation. The Spectrum Analyzer displays the frequency spectrum of the modulation envelope. This allows the operator to view the bandwidth of the transmitted signal directly on the coax sensors in real time. It really helps to maintain a very clean RF signal.

PB-2086A counter mother-board and IC MSM9520RS replacement module


A digital counter board PB-2086A bought on internet was added to the FT-101Z/MK2. As expected the IC MSM9520RS was faulty (for unknown reasons the IC's MSM9520RS from early production fail after a certain time of operation). Here are some symptoms: unsteady and erratic display or digits (all the time or from time to time), a fixed frequency on display, a dead display, display OK on RX and TX low bands but unsteady when TXing on high bands.

The FT-101Z with the added PB-2086A counter and IC MSM9520RS replacement module


Apart those in use in my transceivers I have two more of these counters. They were bought on internet and were faulty. But there is a nice way to make them working again. Thanks to Teruhiko JA2SVZ who made a tremendous job in producing a replacement module kit for the IC MSM9520RS. The two pictures on the left let you see a replacement module kit which is now in use in my FT-101Z/MK2. For more information about the JA2SVZ replacement module kit click here.
