Having spoken at length with Clark tech support, they recommend any engine oil as a lubricant for the SCAM 12 mast. They also said that the seals will be fine with engine oil and will not deteriorate.

Opps... forgot to mention it is the 10ghz whitebox

I recently bought a whitebox system which arrived in a very poor state. The oscillator 1st stage had several burnt out resistors and the 2nd stage transformer was shorted. All these easily fixed. But

Is that not a tant by the multiturn preset? Also... a burnt resistor above the edge connector? Mark

A bit more investigation and the 432 signal has 1/3rd the frequency shift of the 1296 signal. My 1296 signal is louder but that is very likely because my 432 setup is quite lossy and the antenna has l

I would have thought being the same size and layout as standard canned pcb oscillators the pin outs would be the same. Viewed from underneath, pin at pointy corner being control voltage, then anti clo

Looking at the waterfall trace Julian supplied makes me think it is radar. The trace I get on the radio waterfall looks very similar. Only difference I could see from the video was the slow movement o

Hi All, I've been receiving the following signal about s3 in Bar Hill on and off most evenings. Link to file here: https://1drv.ms/u/s!AiEXawJdr6xkok1dasBIIfEuvM9U There is also an image at the same t

Paul, Im interested in one jupiter board, who do i contact and how much money is required? Mark M1MPW

All you can do is put up a note on your QRZ entry and post messages to the effect on the bulletin boards where the amateurs involved use. The only thing you may worry about is if a stupid amateur take

Many thanks for the info. Glad I'm not the only one! :-) Can anyone think of a reason why the on/off switch is in the low voltage supply? Mark M1MPW

Chris, What are the symptoms? Mark M1MPW

Thanks Chris, The iron works fine, I've just taken the back off and found that it is the transformer that is humming. And a bit of reading suggests that not all transformers are perfect so some hum is

I'd like to know if the PSU is supposed to hum/use around 6w when the power switch is in the off position. If they do, I'll leave it alone and just disconnect the mains when not in use. Many thanks, M

What I thought I heard was that placing a dissimular yagi within an INCH or less of the yagi in use would not produce any significant alterations to its gain/pattern. Did I hear this wrong? Or did Ken

Hi All, After leaving the Microwave round table at martelsham... I've been thinking about Kent's talk on the apparent lack of need to separate dissimular yagis. Does this mean that G3SEK's webpages on

I'd just like to thank the anonymous donor of what appear to be four brand new black spot fets that appeared in my post today. I promise to take extra care checking that a negative bias voltage is ava
