I can not run GGridPA, the error: Error readingRichEdit1->Lines.strings:RichEdit Line insertion error.
 How to solve it? my OS is Windows 7 64bit  and Windows 7 32bit.
  Thanks!

Hi Iain,

Please, check this piece of software called GGridPA
It is very useful.

GM Iain,

I've included a link here http://www.nd2x.net/gs35-HF.html  but
seems to me easiest to just calculate the plate load impedance given your
planned B+ value and tap accordingly per band.  Whether its variable or
fixed on the schematic really doesn't matter if you plan ahead.  GL

Hi

Wonder if the group can point me in the right direction ?



I am building a GS-35B Amplifier for the HF bands and wanted to use a Fixed
(tapped) coil in the pi-tank rather than a roller inductor.

Does anyone know of a published (on the web) design of a GS-35B amp for HF
with a fixed tapped coil in the output ?



Thanks in anticipation

Iain G4DPF
