Available PCBs?
Are there any Multiband BPF MK1 boards available that anyone knows
about? Failing that, are there any MK2 boards available?
Thanks!

BPF Mk1 poor performance
4
I recently bought a bunch of parts and boards to build a multi band
transceiver including some of the new boards that Andy recently
produced. Amongst the various modules was an almost complete kit of
parts for a Mk1 BPF using the spectrum coils. Over the last couple of
days I put this together along with cheap ceramic capacitors that I
sourced locally in addition to some that were supplied with the boards
and other parts.
Once I fixed a minor problem where I had a shorted 390 ohm resistor in
one side of the diode switching all seems to function, sort of. I'm
using 1N4148 switching diodes with 100 ohm resistors as per the Mk1 BPF
build instructions.
I have a VNWA3E and have used this to sweep and adjust the filters. All
9 filters with the possible exception of 20m look to be quite poor. Most
having significant in band insertion loss, several up to 20dB! All
filters do tune and I can approximate the curves shown in the various
documents though not exactly in all cases.
I am wondering if the locally supplied ceramic capacitors maybe of such
poor quality as to affect the filter Q or if this is a non issue. If it
is what is recommended. I would also like to know if anyone has made
comparisons against the published data and found it sufficiently close.
I plan on building the later toroid based filter for my multi band t/r
but would like to use the canned coil version for other projects,
external switched filter for an SDR as an example but would hope it has
better performance than the current Atten-u-filter!
Any thoughts.
Thanks

VFO and questions for builders.
3
Andy and all,
? ? ? ? ? ? ? ? ? ? ? ?I was wondering if there were plans to produce some VFO boards? If not what is everyone planning on using. I have seen an (AK2B) design with a Si5351 chip utilizing the Uno but controlling BPF's and LPF's are where I am falling short and I am not understanding how I could accomplish that.
Any insight would be greatly appreciated and most welcome. ?Ian K3HQL

MK2 Exciter PCB Correction
Hi Everyone
The latest batch of MK2 Exciter PCB's that have been manufactured and sent out over the last week have a small but easily correctable error.
Please see the attached PDF file for further details and solution.

Hi Andy,
Just to let you know the board package arrived, seemingly safe and well.
It will be another week or two until I'm in UK to collect it but looks good.
Many many thanks for this brilliant service.

PCB Pre-Order Update!

Hi
First of all thanks to the 20 members who responded to my email and confirmed their shipping location I will now email you with a cost to ship the PCB's you are interested in so expect an email from me within the next 24hrs.
I have not received an email response to confirm shipping location from the following group members:
socijalizam1@...
pd0sbc@...
vu3pyg@...
bakercrich@...
kon.stamou@...
It is important that the following members confirm their shipping location, by return email, once this is done I can confirm what the total cost would be to ship the PCB's you are interested in.
Regards

Boards and stuff.

Hi Andy,? ? ? ? ? ? ? If you have a PA board in stock I will take one if it is available. Also I am making my own board but would not mind having an Exciter PCB as well. I will add my name to the database.
Thanks Ian ?K3HQL

Update On PCB Availability & Pre Registration
5
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.
Regards
Andy de G6LBQ

G6LBQ MK3 HF Linear Amp Database Live!
Hi everyone
I have added a database in the Group where you can pre-register your interest for pre-order of the MK3 HF Linear Amplifier PCB.
PLEASE NOTE: ?If I have already reserved you a MK3 Linear Amp PCB from stock your name will be added to the database for information purpose so I can track interest..
Further details of the MK3 amplifier can be found in the files section in my G6LBQ Irwell Transceiver project folder.
All members who have registered there interest on the
database will be contacted by email once there is sufficient interest to
consider placing a manufacturing order for the PCB¡¯s. In the email, I will
confirm the PCB cost, shipping costs and you will have the opportunity to
confirm your order.
Please note that any member who registers there interest on
the database can remove themselves from the list should they wish to do so.
Regards
Andy de G6LBQ
