@farpointfarms have you tried the meter on your HF radios since it says it covers 3-30MHz? My neighbor gave me one, haven't tried it yet. My HF radio is in the shop
Hi Farpoint Farms I just recently was given a Ham radio complete set, made by heathkit sb-404a, I have a couple of Cb tuners, One of them is a nice Mura CBT-25, Will this work, to tune my ham, I,m just reading up on ham test, Have a lot to Learn, I am going to build a all band Antenna, maybe dipole Setup, Thanks for any help
Hey Eric I just found one of these meters on eBay. I offered them $15 for it and they took it! Had to pay more for the shipping lol. I just hope it works when it gets here. I think it will work well with the rest of the radio shack CB stuff I'm using now lol. Is it easy to hook up? Is there anything I'll need to hook it up to the radio? Talk to you soon Josh
I have one like that but it has Blue lights behind each meter.....I cant find the stinking power cord ,YET! LOL That's still a good buy (not a good BYE) :) Another old radio man told me the needles will some times be dirty,bend, jam up or can be frozen in place due to static electricity. He used a magnet once to unstick one. Might try it! $$$$$$$$$$$$$$$ I have used a 102"whip for 30 years, but my new Dodge Grand Caravan is all plastic junk around the back bumper(boomer) so I installed that Tramm 300 magnet antenna you reviewed. Got great reports with it in my mobile Cobra 148 GTL! Thanks OK, Back off the key! BoogeyMan FAR West Texas Chnl. 14 El Paso Tx.
I have one! All three do work and the only one I don't completely understand is the modulation. You said "between 70&100". When I key my radio and talk, the needle goes "all the way". I'm guessing that means I'm over modulating. Had one contact that said I sounded distorted. When I turn down the mic gain, modulation drops. Also while talking modulation drops. Does this sound normal?
OK so when your looking at modulation you want to be close to 100%. That will give you the strongest audio coming out of your radio. If you go over 100% that's when distortion kicks in. at 120% you'll sound loud, but but your audio will sound muffled and distorted. Its better to have to little modulation than to have to much. At least with to little you will sound clear, just a little faint. You can adjust your Mic gain knob (if your radio has one) to get that modulation down to a good number. If your radio doesn't have one, try getting a power Mic and then dial back the power coming out from it to get the sound right.
Whoa! Your modulation should bump your signal up a scosche, what we called "forward modulation." Your rig should make receiving rigs' S-meters dance as you talk between dead carrier and voice. But with no distortion. Get hold of a D-104 power mic, they're powerful, loud, and it takes a lot to make them distort because they feature excellent voice clipping. At least, they used to, don't know about now.
I bought one recently. Works great. The previous owner installed blue led backlighting.
Nice 👍
I just bought one of these from America (new old stock) all in all it cost me about £135. Its only money.
"Micro Not A" he called it. 😂 Hilarious.
Ya, making fun of the way people talk is cool.
I dig it! There’s a huge outdoor flea-market this weekend, I plan on going up in a few hours and going on a CB safari! I love old RS stuff!
Good Luck!
The Realistic brand base and mobile Xcievers were called "bleed boxes" for their lack of adjacent-channel rejection.
Take part the pot for modulation meter and clean wipers worked for me
Thanks for the tip on that
I have one in the garage, I need to dig it out and see if it works.

I haven't tried it on other bands, but I would imagine that it would work fine.
I like it, I do repair cb's i am an electronics tech by trade and I have that very meter and it all works and its fantastic little tool for tuning.
Yep I have one of these bought it with a realistic 490 base station and it all works pretty good meter

Sounds like a great set up!
@@FarpointFarms Do you think i could use the Mura cbt-25 on ham antenna tuning
I remember that. I loved it, i miss it today
Just bought one of these from a American seller. New old stock in the box never been used. £140 roughly.

Did you try setting the left hand toggle switch from it's "cal" position up to the "mod" position to get the middle meter to work?

Oh, geeze, I had one of those!
Wish I could find stuff like that around here
Keep looking. I'll hit a dry spell and not see anything cool for months, and then hit the mother load like last month.
Mine had 2 dead meters. A little shot of contact cleaner fixed them right up
Very cool!
What is the mon hole for
Probably the the switch for cal and mod is dirty, try spraying it with contact cleaner.
Do you have a linear..? I have a big one for sale.
sheila Lambert What kind linear / size and how much???
Fix it Steve! I’d watch that video.😊
Yes. I still have it. Lol. It’s not small.
Bardzo fajny miernik mam podobny i działa cały czas
Do you still have your Montezuma toolbox around?
I sold it to a co-worker 2 years ago when I decided to go part-time. He works with me so I still see it everyday. No problems with it yet!
Thx for the reply, I'm needing to upgrade my toolbox
