I am retired and was fireman in the Vaucluse department (Provence) with the rank of Colonel. I was Operational Director and specialist of the creation and managment of control rooms using computers and radio transmissions for the dispatch of rescue teams and also for crisis management. I was also involved in the definition of the FDMA digital radio network used by French firemen (Antares Tetrapol network). My main interest, out of ham radio, is photography.
I get my ham ticket in June 1974.
I love Collins and Drake rigs.
This is my 2015 station. An ANAN100 is now the main rig, but of course the Drake TR7A is still there, and a Drake R7 has been added. Drake was years ahead with this fine combo.
I sold my Collins KWM-2A transceiver and I cannot resist to write a small tribute to Rutebeuf and Art Collins :
" Que sont mes Collins devenus
Que j'avais tant entretenus
Et tant aimés
Ils ont été trop dispersés
Je crois l'argent les a ôtés
La radio est morte
Ce sont Collins qu'argent emporte
Et il sonnait devant ma porte
Just before getting the Drake R7, the Drake TR7A was coupled with a RV7 external PTO.
This is my former station ; the main goal was to set up a high performance station that could be easy to service.
With this station, no SMD, no microprocessor and no tricky circuit.
The following picture shows my 2014 station ; the power amplifier was replaced by a very special Drake L75.
Very special because it has no bandswitch, but a roller inductor coupled to a turns counter. The input circuitry has been replaced by an automatic antenna tuning unit (LDG Z-11 Pro II). The amplifier covers continuously from 3 to 30 MHz.
A Yaesu FT-817ND has also been added to cover 2m and to do some WSPR tests.
The MSI "All in One" AP 1900 personnal computer has now been replaced by an Intel NUC I5 with 16 GB of RAM, a 120 GB SSD and a 1 TB 2,5" mechanical hard drive. Win 7 64 bits runs my softwares.
This is a close view of my new Drake L75 amplifier with its input LDG circuitry on top.
This was my 2014 station. The main rig is a Drake TR7A with a RV7 external PTO. The second rig is a Collins KWM2A. The amplifier is a restored Heathkit HA14, giving 400 to 500 W output on 80, 40, 20, 17, 15, 12 and 10 m. The ATU is a Palstar AT2KD. The logging software is Win EQF.
The Collins KWM2A has been modified for better CW use and it includes a plug-in module with a 500 Hz CW quartz filter. This module plugs into the connectors dedicated to the noise blanker. This modification also corrects the shift between transmit and receive due to the tone oscillator used to generate CW. You may also notice the concentric RIT/RF gain control. This modification is done without a single hole and only a slight alteration of the original cabling.
This modification has been published in the October 2014 issue of QST.
The item next to the TR7A is a professional Thomson CSF preselector covering from 1,8 to 19 MHz. Two high pass filters, one for 17 and 15 m, the other for 12 and 10 m can be switched on. This preselector is extremely selective and has a very low in-band attenuation, much better than the Yaesu mu-Tune system. I integrated these filters into a home brewed cabinet. This preselector also includes a switching system for transceiver (unlike the TR7A) which do not have access to the receiver path.
The item sitting on the preselector is an utility and switching box. It permits switching the Turner +3 microphone, the loudspeaker, the headphone and the key between the Drake TR7A and the Collins KWM2A. It includes also a PicoKeyer, passive SSB and CW filters, a tone oscillator to tune the ATU and the amplifier in SSB mode and a TF Set. The TF Set (yellow button) allows to check my transmit frequency when working split. So, when working DX with split frequencies, I can check my transmit frequency and position it at the right place. The red button is used to send my call sign in CW mode.
Inside my home brewed preselector and switching box :
This is my former vintage QRP station. The HW8 has been slightly modified and all mods are reversible and use the original hardware. The filters center frequency and transmit/receive shift are now 500 Hz, more pleasant to my ears than the original 700 Hz, and a S meter has been added. Dial and S meter are lighted with blue LEDs.
The rig is gone to the USA, in the hands of a happy howner.
Here is a picture of my home brew S meter module.
Outside, my antennas are a Hexbeam from SP7IDX at 9 m (30') and a center fed dipole with balanced ladder line.
I homebrewed a rotating mast, with a Ham IV rotator at the bottom and a GS065 trust bearing at the 3 m level. The auxilliary mast is made of stainless steel. The main mast is a Spiderbeam 10 m HD aluminium mast. A rotating guying system at the top uses a teflon plate and Deltex guy lines.
