Hi Everyone

Just a quick post to update everyone who is interested in PCB's for the transceiver project.

The databases that I created in the Group for pre-registering an interest for MK2 BPF and MK2 Exciter PCB's has gone well so thank-you to everyone who has put themselves on the lists.

With sufficient interest I can now warrant making inquiries with PCB vendors to get an idea of cost, once I have done this I will email everyone who has registered their interest with cost details.

If you have shown an interest to get PCB's but have not registered on the Group databases please register as soon as possible.? The databases can be accessed from the Groups.io menu list present on the left hand side of your screen!

I will be adding more pre-registration database soon for further PCB's so please keep an eye on the Group Database section.

Hi Ken

Yes it is newer version than the MK2 original used with my SSB Multi-band project.

The MK3 was developed with the Irwell project in mind, its a smaller board and does not have a pre-driver stage prior to the finals.? When I produced the MK2 HF Amp it was universal and could be used with a standard BitX or other transmitter with only a few mW output. The MK2 Exciter produces several hundred mW of RF so in essence the pre-driver stage in the MK2 linear was overkill and required attenuation at its input to reduce (waste) rf energy.

Hope that answers your question.
