Anglian 144MHz high performance
assembled Anglian transverter boards are now all
sold. I do, however, have a few SMD partially
assembled boards left in stock. Finished off by
hand assembly, these Anglian kits are £120 each
G4ZTR has made available a
suitable predrilled heatsink for the 30 and 60W
PA modules. See John for details and purchase http://aerial-parts.co.uk/
Anglian 2m transverter
is a high performance 144/28MHz transverter
module featuring a ready-assembled PCB. All
SMD parts are pre-installed on the board. You
only need to solder the board into the
tinplate box, solder in the crystal, coils and
The kit comprises a tin plate box, connectors
( SMA) feed-through capacitors, tuneable
coils, crystal ( 116MHz by Krystaly) and a few
other parts needed to complete the build.
A comprehensive PDF of the transverter
assembly is here.
Updated to V1.2 This covers a mod to
improve transmit receive switching speed.
144MHz 8W power amplifier short kit
144MHz version of the 70MHz amplifier
using the Mitsubishi RA08H1317M module
is described in this article.
PCB short kits are available at £8
each. The Mitsubishi module is not
included. Mitsubishi power modules are
available from GH Engineering in the
UK and from AngliaLive in Wisbech.

I have available two versions of the
PGA amp as well as several of the SPF amplifier. As the
PGA and SPF amps have several similar characteristics, it
is prefereable that you contact
me to discuss your requirements.
The plain, unfiltered PGA PCB version is a widebandband
(30MHz to 3GHz), low noise amplifier.
If you need filtering then the PGAV2 board has provision
for adding a low pass filter or a bandpass filter. A
limited number of filter designs and parts are available.
See the PDF for details.
Both kits are £13. The filter
components are an additional £1.50

Recently added. Micro X
PCBs from WA5VJB. These boards accept MMICs and
discrete devices in the popular Micro X package
style e.g. ERA, MSA/MAR.
The boards are available in 'panels' of two at
£5 pair. The material is 0.79mm FR4. Termination
is cable, although a few SMA through hole boards
are also available.

range of PCB antennas have become virtual
industry standards, widely copied at higher
prices in Europe! These are the original and
best PCB antennas, developed over a long period
of time and used as OEM antennas by many
commercial, monitoring and test houses in the
USA and elsewhere.
I carry a wide range of these antennas, so if
you see something in the list below that you
want or on Kent's web page
ask me first!
Kent will also shortly be offering
Multicopter/quadcopter/drone antennas. I expect
to have these available in the UK when they are
