YAESU FT847 Earth Station

A full-power transceiver covering HF, 50 MHz, 144 MHz, and 430 MHz bands in a package about 2/3 the size of an average briefcase. Ready for action on SSB, CW, AM, FM, and digital modes, the FT-847's ultra-compact size makes it ideal for serious base stations use, and well as a variety of portable and mobile applications, including Field Day, DX-peditions, VHF/UHF "Rove" operation, and RV installations. And long-term reliability is ensured by the rugged construction, featuring an aluminum diecast chassis which doubles as the power amplifiers’ heat sink.


The FT-847 includes crossband full duplex operating, so you can hear your downlink signal while transmitting (on a different band) on the uplink. The FT-847 is ready for operating on Mode A (TX: 145 MHz, RX: 29 MHz), Mode B (TX: 435 MHz, RX: 145 MHz), Mode J (TX: 145 MHz, RX: 435 MHz), or Mode T (TX: 21 MHz, RX: 145 MHz).

Alinco DR-135DX

The Alinco DX-10 is a capable, compact, multimode 10 meter transceiver. It will operate in LSB, USB, AM, FM or CW modes. Operation is from 28-29.7 MHz. Power output is adjustable (0-25W SSB and 1-12W FM/AM/CW). This radio does not employ a traditional VFO. Rather, frequencies may be stored in the expansive memory system and then adjusted by the fine tuning. 

The meter can display S/RF, SWR or DC voltage. Scanning is supported. The radio features SWR and power supply voltage protection. 

Tuning steps may be set to 10 Hz, 100 Hz, 1 kHz or 10 kHz. This radio requires 13.8VDC at 6 amps.


With a frequency range of  25.615MHz to 30.105MHz, in 6 channel banks of 60 frequencies this is my secondary 10 metre transceiver.

PIXIE 7MHz QRP CW Transceiver

The PIXIE is a low power QRP CW transceiver kit. Constructed the PIXIE transmits on 7.023MHz with an output of 0.8 Watts at 9 Volt / 1.2 Watts at 12 Volts. 


For those holders of the UK Foundation licence this is an ideal, cheap project to use as part of your Intermediate course.


The Uniden Bearcat UBC3500XLT is a Europe marketed scanner from Uniden similar to the BR330T USA version. With 2500 memory channels this scanner operates on frequencies from 25MHz to 1300MHz (with gaps).


This scanner features close call, a Uniden specific feature that instantly tunes to signals from nearby transmitters. Close Call can operate by itself or in the background scanning and/or searching. The feature is designed to catch signals that are "Close" (hence, the name). While you might not get a hit often, it should be the case that any hit you do get is from a relatively nearby transmitter, so could be of enhanced interest to you.


For the Close Call feature to detect a signal, that signal must be about 15-18dB stronger than the RF noise floor in the band being checked. This means that there is no real way to predict the range within which signals will be caught.


This is my primary AM & FM scanner/station monitor.

Hustler 4BTV multiband HF vertical

My home HF station runs with a variety of HF antennas including the Hustler 4BTV. With 4 Bands - Coverage 40-10m - Bandwidth Full - SWR 1.15:1 - Power 1kW - Traps 25.4mm formers - Tubing 31.75mm - Bracket size 44.45mm - Height 6.52m - Weight 6.8kg -Radials provided by user, can be ground mounted.


Exclusive trap design makes Hustler traps ultra stable and dependable. With Hustler verticals, you can not only adjust frequency by tubing length, you can actually tune the traps for up to 2MHz shift. Large diameter tubing gives full bandwidth on 10m - 40m with VSWR typically better than 1.6:1 at band edges. On 80m you will achieve around 80kHz bandwidth. Absence of tapered tubing makes this antenna really rigid and the 0.315in base tube wall adds to the rigidity. Longer than comparable verticals, these antennas are really efficient. As Hustler says, these antennas offer solid signals, solid construction and solid value.

Arrow II VHF/UHF portable satellite antenna

Weighing about 20 ounces and measuring 37 ½  inches (94 cm) long the Arrow II is a compact solution for working amateur satellites.  Made from ¾ inch square aluminium the boom is designed to split for easy transportation.


Both VHF and UHF driver elements are fed from the gamma match, via BNC connectors into a duplexer for single radio/split mode operation.


While no performance figures are given for the Arrow II, typically a 3 element VHF beam will give 5dB gain on 145MHz and a 7 element UHF beam will give 7dB gain on 434MHz.

The Gold Elite microphone is designed and crafted specifically for amateur radio communications. It contains two distinctly different high performance dynamic elements that are available at the flip of a switch to meet the different types of communications.


The WIDE position has the HEIL Elite full range element producing smooth articulate 60Hz – 16 kHz audio with the traditional Heil +4 dB peak centred at 2 kHz. This gives the new Gold Elite excellent voice articulation along with its ‘big bottom’ low end that is so important for producing a well balanced, studio quality SSB signal.


The NARROW position features the HC-5.1 dynamic element producing a smooth response of 200Hz - 8 kHz. The HC-5.1 element is designed to respond to those older rigs as well as today’s transceivers with onboard DSP EQ. The HC-5.1 produces full range broadcast audio as well as the tailored DX/Contest audio by simply adjusting your EQ. New mic technology to meet today’s new DSP technology.


This is my primary microphone for HF and is used with my Yaesu FT1000MP MkV.

Funcube Dongle Pro Plus

This is a software defined radio receiver which has a range from 150kHz to 240MHz and 420MHz to 1.9GHz. I use this for testing and monitoring the Funcube (AO-73) and Nayif-1 (EO-88) Amateur Satellites. I use the Funcube and Nayif-1 dashboards to download live telemetry data from the satellites on each pass. This is then uploaded to the data warehouse for use by schools and students as part of their science and maths work.

Orbitron Software

Orbitron is a satellite tracking system for radio amateur and observing purposes. It's also used by weather professionals, satellite communication users, astronomers, UFO hobbyist and even astrologers. Application shows the positions of satellites at any given moment (in real or simulated time).


It's FREE (Cardware) and it's probably one of the easiest and most powerful satellite trackers, according to opinions of thousands of users from all over the world.


I use Orbitron at my own station and it is also used daily at the National Radio Centre GB3RS at Bletchley Park.

PstRotator & Satellite Tracking Software

PstRotator supports separate antenna rotator controllers for Azimuth and Elevation control. It can control two separate rotor interfaces: one for azimuth and the second for elevation, or it can control a single azimuth + elevation rotor interface. It is compatible with several different interfaces and rotators including those using Yaesu GS-232 format.


Connect the rotator interfaces to PC using the RS232 ports or USB to serial converters, and select the communication ports from the available COM Ports.


This is an excellent piece of software for the amateur satellite communication enthusiast.

Live ADS-B and Mode S Flight Tracking

I collect live aircraft transponder data using a Raspberry Pi with a Software  Defined Radio (SDR) dongle  attached.  A collinear antenna feeds  the received signals  to the SDR  which  are then  processed  by  the Pi.  Receivers  around  the  world  send  this data  over  a  real-time  connection  to  FlightAware,  which  aggregates  the  data and provides flight tracking data and interfaces. 

Aircraft with an ADS-B transponder broadcast their identification and this three dimensional position (latitude, longitude, altitude) on 1090MHz or 978MHz, which can be received by a radio within line of sight of the aircraft (a maximum of 300mi / 480km at cruise). Approximately 70% of airliners around the world and 10% of private jets currently have ADS-B, whereas nearly 100% have Mode S.
