To use up some of the eighty or so MC145170 VHF PLL chips I'm sitting on,
 take a look at
www.g4jnt.com/VHF_Synth_Module.pdf   and   www.g4jnt.com/VhfSynthModule.zi=
p

This is a design for a self contained syhthesizer from operation up to abo=
ut
170MHz, with proper choice of components.  It is designed to fit into one=
 of
Alan G3NYK, 's  tinplate boxes (37 x 55 x 30mm).   The synth has a
self-contained PIC with mini-operating system for control over a serial
RS232 link.

The .ZIP file includes design utilities and a mirrored 2X .PDF of the PCB
track side if you want to make your own.

If there's enough interest, I can get a proper PCB made up, cost unknown=
 as
yet - but past experience suggests 25 off is a good break-even point.
The chips themselves are =A33.50 each from myself (Paypal is OK to
 ac.talbot [at] btinternet [dot] com )    Discounted prices available for
more than one - please enquire.

The chip used is somewhat ancient now, but still forms the basis of a very
decent VHF synthsizer.
When (if !) all these chips get used up,  it won't be repeated.
