CB Radio Discussion Board / Magnum S9 Backlight Fault
« on: August 30, 2024, 10:29:58 am »
I'm currently trying to fault find an issue with a Magnum S9 backlight. Its a very intermitant fault, sometime it will work fine all the time its on until a power cycle, and other times it will not work from cold; sometime just a small flash from the meter backlight will be the only indication that it wants to work.

My suspicion is it has something to do with the dimmer circuit which works accross all backlights for frequency counter, signal meter and channel number display.

I have all the schematics, which I'll post here.

Has anyone else has this issue, and being able to isolate the nature of the fault?

Technical Corner / Re: nrg 40 amp

I'd probably recommend checking the condition of the yellow trimmer caps, even better would be to replace them if they have been subjected to many turns. Also they seem to attract dust and dirty easily which can be dragged inside and damage the thin Polymer film separating the plates and cause a short.

Here's the coax transformer cutting lengths for the above board. The total length is the most critical part, other lengths have room for discrepancy.

HomeBrew / AM Valve Transmitter.
« on: June 07, 2024, 08:51:32 am »
Video of an AM valve transmitter, which has been modified regarding its modulation technique. The video talks about the change from screengrid / clamp tube modulation to series cathode modulation.

Since the video its finally been upgraded to "Heising" modulation, which is very similar in some regards to conventional technique of plate & screen modulation.

Does anyone know whats going on with LHH these days. Once the shortwave legend, but I can't remember the last time I heard them on 6205KHz? When they was on 4026 ish their signal was good in the evenings and early mornings. I know the TX was somewhere in Ireland.
