Got a usb2 mini-B cable, installed the?CH340 driver and fired up uBITX Memory Manager. As I thought the s-meter had been set in memory by the previous owner (see attached) and I guess it's just

Robert, Simple conductive shielding paint will do the trick. Easy to use and apply. This is just one of many products available. I use it in many

I've got some info stored away of using a plasma based vacuum coating system (homebrew), and it might be a great way to coat the interior of cases with a transparent but conductive coating.? From

Yes it locked up with "TX:14.225.00" etc displayed on the second line of the LCD except some of the characters were garbled with nonsense patterns. A capacitor across the PTT line and ground on the

Gahhh, So according to that calculator, skin depth is inversely proportional to the square ROOT of the frequency.

Thanks! Got it! DC

A minor clarification: At 60mhz, skin depth is 8.4um. At 60hz, skin depth is 8.4mm. So according to that calculator, skin depth is inversely proportional to the square of the

A couple of times my unit locked up but most of the times, keying the mike multiple times released the transmit lockup. I haven't worked on ti yet but I intend to put a small cap and RF block of some

It probably has to do with being able to lay it out and take it up which they do frequently. They don't worry about skin effect with Stranded wire at 60 Hz.? Earl Cox? KB5UEW?Reply or E-mail me

My uBITX v6 has recently locked up in the TX mode while I was using it with JS8Call running on my laptop. When yours locked up, was the TX indication visible on the LCD? Mine wasn’t. I realized that

I used to know what it means. https://en.wikipedia.org/wiki/Delimara_Transmitter This only refers to the medium wave 600 Kw tx and its 3 el vertical array. They also had 3 X 250Kw Short Wave Txs with

Gordon, Gathering back memories from engineering school . Skin effect is frequency related as well as power and conductance dependent .? At DC no skin effect is present . increasing the frequency

Interesting, that still allows fairly large cables. I read somewhere that the people that run power from those large generators used on remote movie locations and stage lighting setups run parallel

Its the electrical equivalent of "beauty is only skin deep" !

Amazing !!

Skin effect is curious, here's a calculator. https://chemandy.com/calculators/skin-effect-calculator.htm For copper, it shows that the skin effect at 10mhz is 20 micrometers, so at that depth the

Don Have you pressed the knob to get into the menu system? Arv _._ wrote:

Interesting argument. Presuming that the case is all encompassing, then in the theoretical sense, the currents must flow on the outside of the case. Due to RF skin depth those currents won’t be

I'd agree with it coming through the mike cable. Just added this electret fist mic from Amazon to mine ( https://www.amazon.co.uk/gp/product/B07FRCPK88 ) which doesn't appear to have a shielded cable.

Thanks! Got to the menu at long last. Assigned the straight key and am in business. Thank you so very much! DC
