Anglian 144MHz high performance
Anglian 2m transverter
is a high performance 144/28MHz transverter
module featuring a ready-assembled PCB. There
is now no SMD soldering required.
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.
The PCB has been updated to the 'Gold'
version. A number of small errors have been
corrected. These are explained in the
accompanying paperwork. Why 'Gold'? The new
PCBs have gold plated pads!
A comprehensive PDF of the transverter
assembly is here.
Updated to V1.2 This covers a mod to
improve transmit receive switching speed.
Kits are available at £125 each plus
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.

as a built and

will still need to

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

is cable, although a few SMA through hole boards
are also available.
Kent Britain, WA5VJB's, wide
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
