Glenn PCB's for PICaSTAR

Back to main pages.

PICASTAR is an all band (HF) Amateur Transceiver using DSP. No PC is required in actual use. The design is by G3XJP and used home built PCB's.

The original design had no power amp or LPF information. This was addressed by G6ALU and G4TZR with a suitable 20W and 140W PA plus low pass filter. The boards here include those also.

VK3PE has made some group purchases of the PCB's incorporating all changes that were made as the project evolved. The project can still be built though, with home made PCB's.

Don't be put off by the fact that PICASTAR uses some SMD parts. Many Hams have built this rig, all around the world, with varying levels of experience.

The information on these pages is of a general nature and is provided in good faith, but no guarantees are made of it's accuracy or completeness. (Feedback of course, is welcome)

The information has NOT been endorsed or verified by the original designer of PICaSTAR or of any other PCB's that may be contained here.

A project of this kind is intended only for constructors with experience building equipment of similar complexity. These pages are general in nature and are not a substitute for good practice, nor is success guaranteed.

The information here is not intended to be a complete constructors guide.

This is NOT a kit !


This page is for the "Glenn PCB's" made in October 2007, Feb 2008 & April 2008

for builders of a PICaSTAR transceiver.

It's purpose is to provide support documentation where it varies from the official documentation.

All PCB's are based on or are very similar to the originals by Peter, G3XJP.

Panel #1 is 407 x 255mm in size and contains all but the Rx BPF and Tx LPF.

Panel #2 is 410 x 255mm in size and contains BPF plus a 150W PA, LPF and some "bonus" PCB's.

I am indebted to:-

Peter (G3XJP) the architect of STAR, for allowing me to make these PCB's for STAR builders.

Steve (G6ALU) for the use of his 20W pep amplifier and Matrix/Audio amp designs.

Harold (W4ZCB) for use of his beeper schematic which is now a PCB on panel #1

For the BPF panel, (Panel #2, PA and LPF) thanks to Steve, G6ALU and Ray, G4TZR

Chris S. for many hours spent assisting me with the design and drawings for these PCB's.

And to my XYL who has put up with my long hours doing this !

This is Panel #1 of STAR PCB's referred to in these pages. NOTE: No LPF or BPF is included but see "Panel #2" link below for details of these PCB's.

(has error in mode text, to be fixed)

Panel was colour Laser printed onto adhesive backed Polyester material.

Details below are the prototype panels. Link above is the Bersion "B" panels.

May 5th 2009:- Michel, F1CHM is now on air with his Combo PICASTAR !!! See link above for picures.

4th Feb, 2009: After a monumental amount of time put into the re-design to make a ComboSTAR, I have ordered several prototype Panels for this project and will advise how it goes as I build one up. Refer to link above.

March 9th, 2009 My ComboSTAR is working.

{COMBinatiOn PicaSTAR} PCB's arrived 18th Feb, 2009. Three other Star builders are also "pioneers" in the build! One in VK, one each in Germany and France.

ComboSTAR Panel is nearly all parts of a PICASTAR on one panel. ie reduced wiring to the point of only co-ax cabling. Picnmix, DDS and 20W PA are included. NO 140W PA or LPF is included at present due to lack of space. See link in title above.

19th Feb, 2009: PROTO Panel

Make your own Opto Wheel LINK UPDATED 230708

For all that may be interested, Tom, AB9B has just released a freeware program called 'Codewheel' that facilitates generating codewheels for the construction of rotary encoders.

It is downloadable at the following web page (along with a lot of info on decoding quadrature encoders): Download it here -Ray WB6TPU


This is the method I have used to switch the RS232 between the DSP and PnM using a toggle switch. It is not an approved modification.

Alex, AI2Q, has done a similar thing: link updated 20th Sept, 2010

All wiring should be shielded.

Alternate LPF

For a 20W PA, this LPF could also be used, although it might be better to go for Ray's, in case you up the power level !

Tx Low pass filter board. I recently purchased a CDG2000 LPF pcb. 3rd Dec 2007

Kyneton Hamfest and meeting of VK STAR builders !

Paul, VK3XDE, gave an excellent mini-lecture on PICASTAR at the Kyneton Hamfest (VK3) 10th Feb 2008.

Pictures and details here.

Some pictures of PCB's on Panel #2.

BPF and 150W PA amp.

Picture of G6ALU PA to right.

March, 2008

Chris C. has done some work on an Avago™ encoder using a small PIC. See details here. No PCB available for this.

090408 I have now mocked this up after Chris kindly sent me a programmed PIC™ and it's looking good in initial tests with a Logic Probe.

100408 Hooked up to Avago encoder and working fine on Scope. ~16uS pulses and direction Hi/Lo ok.
