Get Started on 10GHz
In the August-2007 edition of Radcom a modern approach to getting quickly started on 10GHz DX was published. RSGB has kindly let us put the full article online:
10GHz Quick Start Project
WA5VJB UHF/Microwave PCB Antennas
Kent Britain WA5VJB has spent many hours working on PCB Antennas, both Log Periodic ( - ideal for multi-band dish feeds) and Patch designs.
Kent now has a wide variety of designs including the very popular wideband log periodics.
UKuG do not directly stock these. Sam Jewell G4DDK is the local contact for them.
Sam's website
has the price list etc for these.

Designs
1kHz Amplitude Modulated Gunn Diode for 10GHz Measurements
This unit was designed by David Wrigley (Scatterpoint-6) to be used with the level meter by Roger Blackwell (Scatterpoint-4 & 5). They can be used with great effect to measure and hence improve antenna performance - see Kent Britain WA5VJB article in Scatterpoint-1.

Latest Version of the 12GHz Prescaler design
This is the very latest version, using the Hittite prescaler, and with a preamp/limiter to improve sensitivity and protect the device. Tests at Martlesham showed good operation from 1GHz (and below) up to 14GHz - 12-Nov-2001

Tuned Audio Level Meter for RF Measurements
This unit was designed by Roger Blackwell and can be used instead of the HP415 signal level meter (Scatterpoint-4 and 5). It can be used with great effect to measure and hence improve antenna performance - see Kent Britain WA5VJB article in Scatterpoint-1.
