A paltry collection of
bits and pieces with no
particular theme except
that they interest me.
Musings on a Quiet Band
CQ DX - this voice doth cry
Without one answer bye and bye.
So little from the void comes forth;
The bands are dead today - of course.
One wonders, “Would it be this bad
When mortal coil has passed?” - So sad!
Or would a limitless span await
When one has passed that 'Pearly Gate'.
Then I could work the universe
And signals from the stars observe.
Those planetary nets I’d love to try
With Martians, Vegans, standing by.
And I’d use my rig of many a watt
With tubes that glow and run red-hot;
To warm the shack and toast my soul
With easy power from a large black hole.
With so much room to play around
Large antennas would for sure be found,
And from their comparison I’d never tire
Of ‘Photon Loop’ and ‘Sky-High Wire’.
Such magazines would there be to read
With favourite topics at just my speed.
And what a set of ads there’d be
With all the latest rigs for free.
Are these but just my dreams - Alas!
Or will this future come to pass?
Yet it's within the realm of dreams
That Paradise affords such schemes.
So I’ll hook my feeder to a star
And follow it both near and far;
And long-time when my day doth come
Perhaps my log will say “Twas Fun”.

- Some Small PIC Projects -
Morse Receiving Practice Aid (PIC18F1320/30) - A stand-alone device that I used as a way of learning the C-programming language for PICs. I hope that it will be of use to those teaching themselves Morse; a mode of transmission far from dead.
HF Marker Generator - This provides separate 100, 25 and 10kHz harmonic outputs when driven by an inexpensive 8MHz computer crystal.
Divide-by-1,000 - A small project showing that a PIC may be used as a synchronous divider for certain ratios. Much simpler than the multiple counters often used in a 10kHz referenced GPSDOs.
ADF4110 Lock Box - A demonstration of a BASIC programmed, 10MHz referenced, phase-locked stabilizer for VHF crystal oscillators using freely available software tools. Please note - the prototype was developed over four years ago and I no longer have the board to help with answering questions.
This, That and the Other
Miscellaneous Sites - Some well known; others perhaps less so.
Of Cabbages and Kings - Trivia that has nowhere else to go. Please excuse any nonsense therein as I very slowly build-up this collection of nothing-in-particular.

Altered slightly from a
sketch by Mike James.
Further ‘Ham Radio’ Verses I & II - All composed in idle moments. It seems a shame to waste them but in retrospect that may not have been such a bad idea.
There is an entirely spurious G3LLV ‘seller’ on the web that I have absolutely nothing to-do with.
