2.5 KV Voltmeter

Posted on 30/03/2013 by G4XFC30/03/2013

Having recently started being interested in HF Linear Amplifiers I needed a voltmeter to measure the High voltage on the anodes of the valves, I have a Bradley meter but it will only go up to 1.2 KV and I needed a 2.5 KV voltmeter to monitor the voltage on the Linear Amp that I was building. I had a 100uA meter in my junk box with a scale of 0 to 25 so I though that I would use that with a series resistor, (forget what it says on the scale as this can be easily changed) so the … Continue reading →

Valve Linear Amp Safety

Posted on 28/03/2013 by G4XFC28/03/2013

Valve Linear Amplifiers WILL KILL!!! If you make a mistake there is no SECOND CHANCE, so you have to be VERY VERY careful before you start working inside them. I am writing this because of some stories I have heard that frighten me, as we are talking about HIGH VOLTAGE in excess of 2.5 THOUSAND VOLTS with high current which is a lethal combination. and I hope that I have managed to scare you into taking notice of the safety measures which should be adhered to. I have worked with mains voltages and above since the age of 16 and … Continue reading →

Boat Anchors! Are we Losing It?

Posted on 28/03/2013 by G4XFC05/04/2013

A recent conversation with Des G4UHZ prompted me into writing this post about the changing ways of today’s Radio Amateur. For those who are wondering what a Boat Anchor is, in radio terms all vintage electronic valve equipment becomes encompassed with the term because it is a heavy piece of equipment with large transformers and tied with rope is suitable for mooring a boat. This is theoretical and I am pleased to say that vintage equipment it is not normally used for this purpose. This post is not about restoration, but more on the loss of essential skills that are … Continue reading →

Saturday 15th March brought about one of my personal favourites in the contest calendar ,this along with ARRL DX are in my opinion more fun…As we will see things nearly went to plan apart from the huge CME that was as the contest started hurtling its way towards good old planet earth… ‘thanks for that Sol’!! Well, things started off great with the blocking of the frequency we intended to use at start of the contest . I started calling a general CQ at 11:00z beaming Russia 50 degrees ish and this is where the fun began. First caller in the bag a … Continue reading →

ARRL DX PHONE CONTEST 2013……

Posted on 19/03/2013 by M5SJM20/03/2013

2nd and 3rd of March 2013 saw the annual ARRL DX 48hr Contest. This contest is maybe one of the easier contests in respect that we can only work Stateside/Canadian stations. Basically point beam to 300 degrees and call !! I decided due to lack of operators to limit our involvement much the same as last year trying to optimise running time during daylight instead of cramming onto 40m in the night with most stations working splits ie. listening above 7.200 and operating below as you know states have a higher 40m band plan, it is allowed to receive on lets … Continue reading →
