The second set of Prototype PCBs were deliver last week and a second unit built up to prove the design works as it should. I'm pleased to report it all worked as planned, although there were still a few very small errors on the PCB. Version 3.1 PCBs have now been ordered and are expected in a few weeks.
The new Anglian 3 is designed as a direct replacement for the Anglian 2, but with a few small improvements. These include transmit enable delay, better transmit amplifier gain distribution, programmable transmit IF gain (for use with ICOM rigs, with their low transverter output level), better transmit IMD, but retaining the same excellent receive performance, lockable local oscillator, separate IF receive and transmit connections and all SMD construction as the 2.
Unlike the Anglian 2 I have no plans to offer the Anglian 3 as a fully assembled PCB, as this has proven to be uneconomic for small production runs of boards with specialist RF parts.
However, I may offer partially assembled boards, depending on demand.
Also, depending on how Brexit affects component purchase (many parts are sourced from overseas), I anticipate the cost being lower than the Anglian 2.
