RF switch PCB dimensions ?

[G4WIM]

Just putting the finishing touches to my Portsdown tx, but don't currently have a RF output switch to measure fixing centres and install.

Does anyone have a drawing of the PCB showing size, hole centres and diameters etc ?

Having this info would mean I could finish the metal then install the PCB once I can order one from the BATC shop.

Thanks Tim

PS - I've had a look around and only found the schematic and parts list info.

The output switch board measures 54mm x 43.18mm.

I have a .PDF file that will print to the correct size if “Actual size’ is selected when you print. It's a bottom view so the holes will be correct if you attach it to the outside of your enclosure.

However I can't attach it here. I have sent a copy to Dave G8GKQ with hopes he will put it on the Wiki.

In the meanwhile here is a .PGN version which you will have to scale yourself.

Hi John,

thanks, as I know the pitch of the connector pins I can now easily determine all the other dimensions !

Getting to quite like the metal work aspect of putting this together

I hope you noticed the overall board dimensions are the first line in my previous post.
If your scaling gets those right the rest will fall into place.

yep duly noted re overall dimensions - thanks

I've just posted the .pdf on the Wiki here: https://wiki.batc.tv/RF_output_switch

The PCB was an excellent drilling jig. So worth the wait.
