‘COMBO P1, P2 & P2a’ PICASTAR NOTES & SCHEMATICS

Last updated 22nd Nov, 2013 by vk3pe (R625 & 626 ARE NOT FITTED. [NF] )

COMBO STAR ‘P1 & P2/a’ Version SCHEMATICS

These schematics are based on the COMBO “C” version which in turn were derived from the original PICASTAR schematics by G3XJP, who designed PIC-A-STAR. See 'picaproject'

Over the years that VK3PE became involved with this project, the original G3XJP schematics have been updated with all of the later updates and modifications and also incorporate modifications by M0RJD. On the “Combo” versions, the original PIC based controller has also been replaced with the ‘Trxavr’ controller by G3VPX. Refer to G3VPX’s web page for full details.

20W, 140W PA’s and LPF designs are by G6ALU and G4TZR. Refer to http://www.radio-kits.co.uk/ for full details of those boards.

These updated schematics form the basis for the various version PCB’s by VK3PE and in this document, specifically for the two PCB versions called ‘Porta-STAR’ in versions ‘P1’ and ‘P2’. The later P2 variation corrected some minor errors on the P1 board. In all other respects, the P1 & P2 boards are identical. Both were available as group buys only, in 2013. Please note:- the schematic is not split into two parts to correspond to the actual PCB’s. There may be some sheets that have components on both of the main boards.

On the P2 and P2a versions only, you might also notice a new, optional 6 pin ‘connector’ provision near the RH edge of the PCB to allow simpler connections to the front panel LED’s and display, especially the TFT. {The P1 version has only a 2 pin 12v out connector here, J10} The additional pins are not shown in the schematics, (or BOM) but are labeled on the PCB.

Band LED orientation:- P2 is correct as pictured. In the middle area of the picture here, the LEDs orientation symbol for the P1 version though, are incorrect, refer to the web page for details but should be as in this P2 picture above.

There is provision on the P2 & P2a PCB’s for 3 series and back to back diodes (6 total) for protection of the Rx input against overload. This is not part of original PICASTAR and the diodes are not shown in the Schematics or BOM, just provision to fit them. (NOTE: on P1 they exist also but there is an error in the pads, only allowing 2 series diodes to be fitted easily.)

Last updated 17-12-14 Footer Page 1 of 25.



The diode area is circled on this picture in red. (just above the reed relay)

The picture below shows the twin shielded wire UNDER the PCB in the monitor switch area. The other end of this cable is connected to the JT11 connector on the other main PCB to the Trxavr control section. (in the cut out corner of the PCB)

Bottom View.

This document and schematics were created on 30th May, 2013

Builders should also refer to www.carnut.info for further build information on VK3PE versions.




Yahoo groups which are very helpful in this project.

You MUST be a member of the Yahoo™ 'picaproject' Group for access to the latest files and software and to purchase these PCB's in the group buys. You need to join this group and digest all the information contained there, on the project and especially the set-up information.

It is also very helpful to be a member of the 'homebrew-radios' and 'picastar users' groups. Refer to those groups for information on joining.

If you wish to fit the colour display, there is a 'TFTA_central' Yahoo group also.

The following pages are the Schematics for the P1 & P2/a PCB’s.

The schematics for the PA and LPF sections are found on G6ALU’s web pages.

For the TFT display, see the Yahoo group, listed above. The TFT display PCB is NOT supplied by VK3PE, Please inquire of VK3CG.

Use of the OCXO is experimental and is provided for those who wish to try it out.

VK3PE has fitted the OCXO type shown here with no apparent ill effects.

You will need to invoke the "x4" multiply mode using HOBCAT (by G3VPX) to obtain correct operation.

VK3PE has NOT tried any other OCXO and cannot comment on suitability or otherwise, of any other type.

NOTE: 'R353' is provided to reduce the Ref level into the DDS if required, start with a high value and reduce until level is less than 3v p-p typically. > For the OCXO specified and running from 3v3, then use a 0R value.

See note below for values.
