Re: LDG AT-11MP : Replacement Meter Backlight Bulb
I have the parts list which lists only "meter."? Does not list a lamp. SEE ATTACHED. My suggestion is to either replace the LED or see if you can find a replacement cross-needle meter with lamp

Re: LDG AT-11MP : Replacement Meter Backlight Bulb
Thank You MA, unfortunately that link is for the AT-11 which does not have a meter unlike the AT-11MP, see attachment. I do have the assembly manual for the AT-11MP, but that doesn't have a parts

Re: LDG AT-11MP : Replacement Meter Backlight Bulb
LEDs are a great fix. You need to know the voltage, AC or DC and voltage and select a proper resistor. Also choose the color you want. I have replaced the dial lamps in a fair number of radios with

Re: LDG AT-11MP : Replacement Meter Backlight Bulb
Another option is use a LED with a current limiting resistor appropriate for the voltage. A drop of hot glue or silicone sealant holds it in place yet allows future removal if needed. This assumes it

The assembly manual has a schematic in the back with the parts list that may or may not be of help. https://www.manualslib.com/manual/2858903/Ldg-At-11.html#manual

Re: LDG AT-11MP : Replacement Meter Backlight Bulb
It looks a lot like the meters MFJ uses. Might be the same bulbs. Take a look at these. This is from page 85 of their current catalog.

Re: RU-1:1 UNUN SWR behavior, Is this normal?
Addendum to my last post: Because I don't own an LDG RU-1-1 myself, I have so far only commented on the chosen design. The implementation shown in the photo shows at first glance 2 points which can

I don¡¯t follow that logic nor do I believe that claim. And I¡¯ve never seen a situation needing such a crazy dual 50ohm feeder ¡ I don¡¯t ever recall any conversation of a 100-150 impedance

I finally found a photo of this LDG-RU-1-1 on the web. The transmission line design with bifilar wound wires is usually chosen for use on antennas with random and sometimes very high impedances (->
