We (myself and RROWLETT) have bought 2 similar Midland CB base stations so we can get one of them fully operational. One was missing an AC power cord and a mic, so we will be getting those items from the other one we bought. Then all that is needed (hopefully) is an indoor antenna, which screws into the back. I think it's no problem finding one on ebay.

Here's what we've got coming :

That's cool there's an online mag for CB...

About the screw on the back base station antenna, the one that came with the JCP base station, came with that base station. I have not seen that before, so I am not sure that it is an aftermarket item?

That Midland magnetic base antennas we bought at Bi-Mart, work better than expected.
I did adjust mine with a SWR external meter.
It works great inside the house and out.

NickyNick has one he uses on his outside "radio shack".

Here's an image of the JCP... Astatic Mic was tested yesterday, not sure that it works right yet.
NickyNick has the base station, and I have another "parts radio" same model coming, no mic or antenna...

I went through the JCPenny manual and it doesn't mention that antenna shown in your pic, or list it in the Replacement Parts section, so it was, as you say, an aftermarket item. It was made specifically for use as an indoor antenna for a base station, so maybe one will pop up on ebay. Otherwise one of those magnetic base antennas work great.

Here's what the JCPenny manual says ☟

Here's one that's similar to the one you show in your pic of the JCPenny base station:

Way too much $$$ for that! A magnetic base (mag base) antenna like you got for us at Bi-Mart, with 18 feet of coax cable, is not only cheaper, but you can distance yourself from the RF (Radio Frequency) radiation - it won't be right in your face like it would be with that antenna plugged right into the back of the radio.

How many people, guesstimate, still use CBs?

If you read net news headlines they often say this, that or the other thing from the past is dead; do not waste time keeping it.
Then you, who still does use it, goes on line looking for a cheap deal on what in the past was the best and find the one for sale are far, far from cheap. Blinking

You'd be surprised what you can buy on ebay for around $50 : fully operational radios if you look very carefully and read the descriptions very carefully.

CB's are NOT a thing of the past; they are America's best kept secret ☺

RpR - If you had ever used CB, you would know that it was hard to get air time before 1999.
Cheap cell phones kind of killed that.
Driving down the highway, or calling out over the air, gets anyone in range, you cant do that with a cell phone.
It's kind of nice now, that you can get on the air, and you can still buy a NEW CB, at most volume retailers, Amazon (see the pic), Walmart, etc.
Not a waste of time, and the old stuff is fun, not having to spend a lot...

I second that ... those Galaxy rigs with SSB are worth every penny spent if you want a quality CB radio. I hear them being talked about on some of the channels that I monitor, and I listened in the other night while someone was helping a distant station fine tune his Galaxy for optimum output and voice quality. But they are by no means the most spendy CB base station that you can buy.

It works great when you have a 35,000' antenna!😀

I guess the external antenna is an after makerket item...
It was probably purchased about the time the JC Penny unit was purchased...
Well, those days are gone for sure...
It's a lot of fun to bring some if this back, for sure...
When the zombies come, and there is no more Verizon, who will be laughing then...

grrrhhh ... 〽 ☠

I just heard something growling and scratching around below my bird feeder at 02:15 AM, if that's any indication of troubled times ...

Well, from what I've been monitoring on the CB channels, there's some good ol' boys that are keeping their networks together, doing commo checks between distant stations, and I've logged some of them as far away as SE Alaska, and 40 miles north of the Mexican border, so that covers quite a bit of territory. They are obviously using "power boosters" (against FCC regulations for CB) such as linear amplifiers, since they admit it right on the air, often describing their equipment; plus hi-tech antennas, or just large antenna arrays like the ham radio operators use. And some of these guys are actually ham operators that get on the CB frequencies to do their daily rants of just plain BS for about an hour a day, just to show off their power output which may be several hundred watts, in violation of CB Rule 10 "Your CB transmitter power output must not exceed the following values under any conditions: AM - 4 watts (carrier power) SSB - 12 watts (peak envelope power)."

Another funny thing about the FCC is CB Rule 13, which says "What communications are prohibited? (paragraph 9) To communicate with, or attempt to communicate with, any CB station more than 250 kilometers (155.3 miles) away;" [quoting from "Plain English Rules - Citizens Band Radio Service, prepared by the Federal Communications Commission, Washington, D.C. - publication date unknown]

Now why is that, I wonder? It's probably something that the D.C. lobbyists for the big commercial telecommunications folks insisted upon, to limit or restrict long distance communication networks that the average citizen could cook up on their own, free of charge, other than the cost of the radio equipment. When you look at the long distance telephone rates in past years, you can understand why AT&T and Bell Telephone would not want "citizens" to develop long distance communication networks on their own.

Maybe it has more to do with interference, thinking a very powerful radio and extremely tall antenna

To crawgarden :

Yeah, that's the thing to have, but if you don't have that, directional (or beam) antennas and SSB radios are the next best thing. CB radios with SSB (Single Side Band) have an FCC allowable output of 12 watts (instead of up to 5 watts on AM), which, I saw it stated, is 8 times more powerful; and the right antenna (not necessarily the highest in elevation) can concentrate your signal to go where you want it, and not just radiating in all directions where nothing is out there to receive it. And that's just the basics - the guys who really know radios and antennas can do stuff that get their signal booming in to their target stations.

But I think during a total civilization failure (extreme natural disaster) if your base station is able to communicate with a scout going out on an exploratory mission for a distance of one mile, that's all you would really need - and CB radios can easily do that with just the basic short little antennas like the "mag base" (for base stations or mobiles) and the "rubber duck" antennas for the handhelds.

GMRS is a good short distance communication device as well.

The FCC is changing some of the rules on using them now.
When you can buy them at Bi-Mart, making FCC license requirements don't make a lot of sense to me, and as you were saying, there are a lot of rules, but I don't believe anyone is there to enforce.
Before they legalized marijuana in Oregon, Washington and California, Law Enforcement didn't do anything, unless they wanted to pop someone for another reason, and they had pot.
It's not legal federally, so you could still be arrested in a National Park, Bank, or Post Office.

The point I am painfully trying to make is, I don't think anyone is going to enforce FCC unless you are doing some other crime, human trafficking, huge drug distribution, smuggling, tax evasion, etc.

Yeah, you're probably right about that ...

I'm catching up on my CB Radio Magazine
http://www.cbradiomagazine.com...

Oh, I got that little Cobra 19 CB (one of the 3 purchased together for $65.76) hooked up and fired up (the one I tested that worked) :

ebay.com

Vintage COBRA 19 Plus 40 Channel CB Transceiver w/ Mic & Cigarette Lighter Plug
Condition:Used - Selling as-is/parts/repair,
with no returns.
Price:US $20.00

Works fine on all 40 channels. Has a mag base antenna on it now. Not a thing wrong with it, other than a little scratchy static spot in the volume control (usual with age). By that description "Selling as-is/parts/repair, with no returns" you would think that it wouldn't work at all. Now I can monitor and transmit on 2 different channels simultaneously. Some guys do that to prevent eavesdroppers from monitoring their conversation : listen on one channel and talk on another (it's called "duplex mode", but it may be against FCC rules - I'll have to look that up, after I have a cup ☕ )

I just looked through the FCC CB Rules regarding "duplex operation" or "duplex operating mode" and could find nothing mentioning it, so as far as I can tell, there are no FCC restrictions on anyone who wants to operate in "duplex" on the CB Radio channels (1 to 40) - except for channel 9 (emergency / traveler assist).

Here is how duplex operation works, taken from a web page outside of the U.S. for UHF CB
http://radioaficion.com/cms/uh...
see > UHF CB
https://en.wikipedia.org/wiki/...
" UHF CB is a class-licensed citizen's band radio service authorised by the governments of Australia, New Zealand, Vanuatu, and Malaysia in the UHF 477 MHz band. UHF CB provides 77 channels, including 32 channels (16 output, 16 input) allocated to repeater stations. It is similar in concept to 27 MHz CB Radio in the United States, Australia, and New Zealand."
see > Current UHF CB band plan (80 Channels)

So instead of having a radio that is capable of operating in duplex mode, you can have 2 CB radios and do it manually : listen on one frequency and transmit on another frequency. The party at the other end (your target station) must do the same. You can pre-arrange with the other party on which frequencies you will be using. It is best to have the channels separated by 10 channels or more to prevent feedback. For example : channels 20 & 40, or 10 & 30, etc.

Bob and Mary will operate in duplex mode - both must have two different CB radios to do this : Mary will listen on channel 10 while Bob is transmitting on channel 30. Mary can transmit on channel 30 (of her other radio) while Bob is listening on channel 30 (of his other radio). Each party can listen and transmit simultaneously much like a telephone conversation, without waiting for the other party to "un-key" the mic. An outside listener will hear only what is being said on either channel 10 or channel 30, not both sides of the conversation.

Even with two separate antenna, I get a lot of feedback screeching with two radios close to each other.

That's cool the radios all work.
I think a lot of sellers do the "parts or repair" only, so they dont have to take returns, and from selling computers and parts on eBay in the past, I know one return can wipe the profit for multiple sales.

Of course, some sellers will try making it sound like they dont know if the item is defective, and it is.
One way to sort some of that, look at the other items they are selling, if its a bunch of estate sale stuff with one or two radios, they are probably honest about not knowing if its good or not...

This is the only radio that worked - I have it set up now with a mag base antenna:

ebay.com
Vintage COBRA 19 Plus 40 Channel CB Transceiver
Price:US $20.00

This one has an internal short in the DC power circuit :
ebay.com
Vintage 1976 Kraco CB Transceiver Model KCB-2330 w/ Mic & Cobra Mic
Condition:Used
Price:US $9.95

This one will power up but will not transmit or receive :
ebay.com
Vintage Royce Transceiver CB Radio With Mic 40 Channel Model 1-648 1977
Condition:For parts or not working
US $12.87

So I have 1 that works and 2 that I can try to fix ...
