Y your correct, I figured it out, they are low voltage contacts for the back lighting.

Awesome Quad you have there, that's exactly what I want to build for my QTH. Thanks for sharing! UDX-4570 Palm Springs wavin!⚡️

If that's the case, there is no polarity and AC powered, the only + and - markings visible are on the large posts. IDK, I'll keep searching the net to see if I can get a positive identification on the posts. Thanks for the reply! UDX-4570 Palm Springs wavin!⚡️

I was thinking the same thing, but I can't see it being AC power, or maybe the manufacturer expects you to use the + or - on the large connections as a reference??? Thank you for the reply. UDX-4570 Palm Springs wavin ⚡️

Hello crew: This is new to me, this S meter has 4 posts on the back, the large ones have a + and - marked on the meter, the two small ones have the letter "L" marked on the meter next to the posts. This meter is a N.O.S. made in Japan, a very nice meter I must add, but as for the two...

Iam confused now..lol Bells, Yikes!!!... he is the clown I purchased my 2970N3 from, it was during the Covid crap and Bells was the only guy that had any radios available, and exactly one week from the warranty expiring, my finals smoked, go figure. Luckily I ran into a local who performed...

This is exactly what iam looking for, Thank you very much. Iam definitely going to give this one a try. Another member dropped a schematic a couple weeks back but , unfortunately it didn't match my transiever circuit board. I'll drop you a line and let you know how it went, Thanks...

It is a through hole board but as for being like the DX, I couldn't tell you. Thanks for dropping the schematic, I'll check it out! UDX-4570 Palm Springs wavin!

Would anyone have the schematic to install an external "S" meter to a rci2970n3??? Any input would be greatly appreciated!

Welp my friend, after about an hour with a magnifying glass and a 5,000 lumen light, the schematics dropped regarding the "External "S" meter" phono jack hook up, I couldn't find ANYTHING on the RCI 2970n3 circuit board that matched the schematic. Any other.suggestions would be greatly...

If your a DX operator, having a low takeoff angle is choice for that sort of work. Like you, and coincidental, my Gainmaster feed point is only 4'F off the ground and mounted to a 50lb cast iron patio umbrella stand, my current location won't allow my to set up a tower, no biggie, My Gainmaster...

Yeah, they're great antennas don't understand why they are only engineered to handle 500 whiskeys, but that's okay.

I have the Sirio gainmaster 5/8 wave, it's far superior to the A99's.

Sorry Moderator for the language, I was besides myself when the meter arrived packed backwards!

I have the "Sirio Gainmaster 5/8's wave, the antenna beats the daylights out of an A99. The Gainmaster is "Center fed" and has an RF choke on the base by the feedpoint to "De-couple" the RF signal from the feed line. You can get these Gainmasters for about the same price as an A99.
