RIP G4ILO
My latest headline Blog regarding the precision ref board will have to take a back seat..
I have just read on G4ILO's One foot in the Grave Blog, that Julian lost his long battle with his illness yesterday: http://onefootingrave.blogspot.co.uk/
Julian was an inspirational writer, anything new he spotted, purchased, or built, he brought to the forefront of his Amateur radio blog: http://blog.g4ilo.com/ Letting us all know his thoughts and modifications. He tried everything from bargain street kits, Baofeng's to Elecraft, and software writing. He enjoyed his hobby and blogging, which was always written to a very high professional standard.
I am going to miss his regular updates on his blog, because I really enjoyed reading what he had written, and couldn't wait for the next item he was going to write about.
My thoughts and condolances must go to his wife Olga and family.
RIP Juilan Moss G4ILO

Calibration time
If your in the right place at the right time a useful bargain can be found..
I had been looking at a way of checking calibration of my DMMs on DC, and this useful board will do that for £4. Using an AD584K Precision reference chip, that will output 4 high stab Volts by the flick of a switch:
10.0 V +/- 10 mV
7.5V +/- 8 mV
5.0V +/- 6 mV
2.5V +/- 3.5mV
Figures quoted are for 15V feeding the input of the board
I have seen these on the Internet at various sources, but my link proved to be the cheapest I could find: http://www.banggood.com/AD548-High-Precision-Voltage-Reference-Module-4-Channel-Calibration-p-932160.html
There is also a full spec sheet on the device at the above link.
I will come back to this when I have boxed it up and terminated it for better protection..

Which is your favourite Baofeng (Pofung)?
We all call them Baofeng the original name, but now they are called Pofung. Who really cares about the name? They are a budget priced HT capable of 2m/70cm and other freqs, they have lots going for them.
Take the survey to the right of the Blog and lets see which one of the 5 you like.
We have the pocket sized UV-3R which includes all models MK1/2. and Plus..
The full sized UV-5R, again includes all models RA, RC, RE etc.
UV-B5 and UV-B6
The rugged UV-82
The budget priced BF-888s 16 CH UHF model.
UV-3R UV-5R UV-5B/B6 UV82 BF-888s
I will let the survey run for a month, perhaps in the comments you will let us know what you like and don't like about them?
Of course if you don't own a Baofeng yet, take a trip down to Hans PD0AC Blog, and do a search for a model which takes your fancy, he has written full reports on most of them:

LNR LD-5 no news is good news?
What could be the QRP rig of the year, many of us are still awaiting for the release of the LNR-5 from the makers of the Par EndFedz antenna.
Since I passed on the news of this radio to G3XBM's blog umpteen weeks ago when I first spotted it on the LNR precision Facebook pages, the only thing I can report at the moment is the LNR website has been upgraded with general information, plus a short form spec, and highlighted Ordering Information Soon.

With Christmas on the way we eagerly await an announcement of price, I guess they are just doing the final tuning before release?
