The G3XBM legacy now in print

Roger "G3XBM" has now published a book titled  "G3XBM Project Scrapbook".

It takes you through his historic years of homebrew construction and operating to present day. To include portable operating, Antennas, LF, HF, VHF, Fredbox and Sixbox designs with full circuit info, even stuff that never got built etc etc.

All Roger's designs, are not over engineered, and very simple to understand and build.

G3XBM the PYE PF1 nostalgia

Well G3XBM is always reminiscing about his time at PYE, I wish I could do the same for Thorn Automation days, but as most of the work was restricted very little of their products have made it into the Amateur world. .

Rogers recent ramble here made me reach for the desk drawer. Out I pulled a PF1 receiver still complete with case.

I cut my teeth on a PF1 with my first taste of 70cm receive back in the early 1980's. What I seem to remember I picked  up quite a few of these at a radio rally for about £5 each! But the crystal was about the same price again, which was required to replace the original to get them working on one lonely channel, or tuned up on a single repeater frequency, in my case being Stafford GB3ZI (433.275MHz). What I seem to remember tune up was quite a fiddle, they used to break into oscillation, as the pull was quite a bit out of the zone of where they had originally been working in the commercial world.

 

This one has seen better days, but most of it is still quite complete apart from the metal shield over the front end. The battery was rechargeable 9V long time expired, but soldering in a 3F23 or PP3 would make it burst into life. So as you can see I have been around quite a while to remember the older PYE generation, but not quite as long as G3XBM. :-)

The Pixie money game!

A couple of months ago my friend and Blogger G3XBM was into buying Pixie kits from China, he thought he had bought a bargain for the £7.00 he paid for the kit?  Shortly afterwards I found the kits at around a couple of Pounds lower than Roger had bought his for. But this was short lived, a week or so later Roger blogged that Andy Cutland had found them for £3.19 pence, this undercut my price yet again by nearly £1.50!!

Well the story continues!! I have now found the Pixie kits cheaper yet again!!! The complete kit as above (inc PCB components and Xtal), all for a penny pinching £2.89p ($4.30 US), and the more you buy the cheaper it gets! Oh yes I forgot the price "Includes" shipping!!

You could buy several kits without busting the bank, and put them on different Bands with Xtal and small mod of low pass filter changes.

Is this now the cheapest Transceiver kit  in the world, or can anyone find them cheaper still??




 

Dad! What are those Pixies on our dining room table?

Quite correct Helen! But not the type you were thinking about, that live with the Elves down the bottom of the garden?

I got involved in this one with G3XBM recently, when he had ordered a kit from a different dealer at a slightly higher price, I was determined to get the price down by using various search method tricks I have come to learn over the years.   
 
The kit(s) arrived from China, within 10 days of ordering. The PCB quality for the kit is excellent! Included is all the components, One Crystal (7.023MHz), and even the schematic and component list were supplied from this ebay dealer. All for a penny pinching £4.70p at the time I ordered!  * Note the price has increased slightly to £5.20p ($8 US) as I write this. This does ask the question though, is this the worlds cheapest transceiver kit including delivery?

I intend to do a couple of mods to my Pixie as I build it, I will replace the 47K preset with a 47K Variable Pot so I can have a couple of KHz Frequency swing or pull to hand when I mount it inside a case. I will also switch in a couple more Crystals 7.030 & 7.040MHz so I can have a bigger spread of the 7MHz CW Band to work with..


The Pixie transceiver has a lot of history too its name, and various mods and developments have been done over the years. If you want the full facts, grab a copy of The_Sprat_Pixie_File from the G-QRP Club Website.

Think about becoming a member of the G-QRP club while you are there, as this club is well worthy of joining! Without them the Chinese would not be producing these kits today!
