F6KQH Radio Club:
The F6KQH Ham Radio Club has the following antennas:
A Levy wire HF antenna in an inverted-V configuration, 2 × 20 m, mounted on a 12 m mast. The antenna is fed with standing waves through a twin-lead feeder line and a CG3000 automatic antenna tuner located on the rooftop terrace. Operates on the HF bands from 3.5 MHz to 18 MHz. Used for SSB and FT8 communications, including national, European, and DX traffic.
Antenna 1: A horizontal-polarization 9-element VHF Yagi antenna by Tonna, with a gain of 13 dBi. Mounted at a height of 34 m at the top of the mast boom. VHF band: 144 MHz. Used for DX SSB communications.
Antenna 2: A vertically polarized VHF/UHF ground-plane antenna by Diamond. Covers the 144/432 MHz VHF/UHF bands. Used for local FM and repeater communications.
Antenna 3: A Diamond QFH antenna (model DP-KE137) with circular polarization and a dual-loop omnidirectional helical design, equipped with an LNA for receiving weather satellites in polar orbit. Reception frequency: 137 MHz.
Antenna 4: A Solarcon HF ground-plane antenna (model Antron A-99), vertically polarized half-wave design with the transmitter’s automatic antenna tuner. Installed at a height of 5.5 m. Used directly on 27 MHz for regional and DX communications over the 26–28 MHz band.
Antenna 5: A Diamond VHF/UHF ground-plane antenna (model X510N), vertically polarized, with a gain of 8.3 dBi at 144 MHz and 11.7 dBi at 432 MHz. Mounted at a height of 5.2 m. Covers the 144/432 MHz VHF/UHF bands. Used for local FM and repeater communications.

The F6KQH Ham Radio Club is equipped with several transceivers:
An Icom IC-7300 HF transceiver.
An Icom IC-9700 VHF/UHF all-mode transceiver for the 144 MHz, 430 MHz, and 1260 MHz bands, with a maximum output power of 100 W.
A Kenwood TS-450S HF all-mode transceiver with an automatic antenna tuner, covering frequencies from 30 kHz to 30 MHz.
A Kenwood TM-255E VHF all-mode 144 MHz transceiver with a maximum output power of 40 W.
A Midland Alan 8001 Plus HF transceiver for the CB 26–28 MHz band.


Ham Activities:
I have my Ham license since 1999. I'm just active on the air since 2025 because I was too busy with my job until now...

I'm a member of the F6KQH Radio Club.

Since 2025, I regularly operate:
SSB, FM voice communications on the 40 m, 20 m and 2 m bands.
FT8 communications on the 40 m, 30 m, 20 m, 15 m, and 10 m bands.
SSTV communications on the 20 m band.
FM voice communications with V/U satellites like SO-50 and ISS.
SSTV communications with satellites on the 70 cm band.
Telemetry with satellites on the 70 cm band.
Weather image reception with satellites on the 137 MHz frequency.


Satellite tracking station:
In March 2026, Guy (F5IBD) and I have built a satellite tracking station.

Our satellite tracking station consists of:
A 5-element 144 MHz Wimo Yagi antenna with 11 dBi gain.
An 8-element 430 MHz Yagi antenna with 12 dBi gain. Both antennas are mechanically linked and mounted on a rotor.
A 2-axis SPID rotor controlled by a remote control unit via a USB port.
An ICOM IC-9700 144/430/1260 MHz transceiver controlled via a USB port.
A desktop PC running Linux Fedora, controlling both the rotor and the transceiver through USB.
The open-source Linux software Gpredict with Hamlib library, used to automatically compensate for the Doppler effect on the transceiver and to automatically track the selected satellite by controlling the rotor in real time to properly position both antennas.
The open-source Linux software qsstv, used to decode SSTV satellite image reception with automatic Doppler effect compensation.
A desktop PC running Windows controlling the transceiver through USB.
The open-source Windows software Gpredict with Hamlib library, used to automatically compensate for the Doppler effect on the transceiver. The selected satellite is automatically tracked by controlling the rotor in real time to properly position both antennas with Gpredict under Linux.
The open-source Windows software MMSSTV for SSTV satellite image reception with automatic Doppler effect compensation.

We use the following software under Linux:
Gpredict.
Hamlib.
qsstv.

We use the following software under Windows:
Gpredict.
Hamlib.
MMSSTV.



I regularly operate with our satellite tracking station:
FM voice communications on the V/U bands using mostly the SO-50 satellite and the ISS.
SSTV reception on the 430 MHz band.


Satellite telemetry station:
In may 2026, I have built a satellite telemetry station.

My satellite telemetry station consists of:
A 5-element 144 MHz Wimo Yagi antenna with 11 dBi gain.
An 8-element 430 MHz Yagi antenna with 12 dBi gain. Both antennas are mechanically linked and mounted on a rotor. I just use this antenna for telemetry.
A 2-axis SPID rotor controlled by a remote control unit via a USB port.
A SDRPlay RSP1B SDR receiver.

I use the following software under Windows:
Gpredict.
Hamlib.
MMSSTV.
SDRUno and SDRConnect.
Soundmodem, SatsDecoder.


Weather Satellite station:
In july 2026, I have built a weather satellite station using an SDRPlay RSP1B SDR receiver.

My weather satellite station consists of:
A fixed Diamond QFH antenna (model DP-KE137) with circular polarization and a dual-loop omnidirectional helical design, equipped with an LNA for receiving weather satellites in polar orbit. Reception frequency: 137 MHz.
A SDRPlay RSP1B SDR receiver.

I use the following software under Windows:
Satdump.
