Do you have old CB crystals?

[PCTEK]

Hello. I am restoring some old Radio Shack 2 & 3 channel CB walkie Talkies. I need TX & RX crystals..

I need 4 pairs. Please let me know if you still have working crystals and how much you'd sell them for.

Thank you.

Do you have old CB crystals?

Yes, I've been diagnosed, and even the ointment didn't seem to provide any relief.

I do have a TRC-206. A great hand held. I used it on road trips for the rear vehicle in the convoy and for coordinated passing maneuvers on back roads in Vermont.

I forget what's in there. I'll have to look.

I have to thank you for inspiring me to find this great collection of vintage radios:

Carolina Pirate's CB Radio Photo Gallery

I also have a 4-channel Radio Shack mobile crystal scanner. High tech! RS was great in the day.

Let me look tonight, but I believe I still have some used crystals that came out of a couple of TRC-206's I use to have years ago. I was thinking I had possibly channels 7,14 and 19?

 

[Daniel]

Well I did find some of them, and I may have some more that were stored away after the last move.

Here is what I have found so far:

Channel 9 Transmit 27.065 Quantity (1)
Channel 9 Receive 26.610 Quantity (1)

Channel 14 Transmit 27.125 Quantity (2)
Channel 14 Receive 26.670 Quantity (1)

Channel 35 Transmit 27.355 Quantity (1)
Channel 35 Receive 26.900 Quantity (1)

Let me know if you are interested, it may be a day or two on checking of the others if they still exist.

Plated type crystals such as those used in old CBs and scanners tend to drift with age used or not so you may have a problem with them being off frequency. I hope you get lucky, finding a manufacturer with them still in their engineering records might be a bit difficult.

 

[PCTEK]

I thought CB was simplex, same TX & RX frequency. I see above that they are not. How is that?

 

[Daniel]

See this link concerning crystal controlled CB's concerning 455 khz differences between transmit and receive:

Why 2 Crystals in older CB for TX and RX?

 

[kb2vxa]

To put it simply, in single conversion receivers the local oscillator is either 455KHz above or below the RF so when they mix the result is the 455KHz intermediate frequency (IF) and other mixing products filtered out. With dual conversion the same principle applies only the offset is the same as the first IF, second conversion to 455KHz comes later. Now you see why receive crystal frequencies are not the same as transmit.

If you do get crystals, please be mindful that the diameter of the pins coming from the crystals are not all the same...don't push too hard when installing them...just a thought.

 

[Daniel]

PCTEK, are you interested in these crystals for the 206?

I too am in need of a pair of transmit/receive crystals for my TRC-215. Already have Ch. 4, 13, 14, 21, 30. LMK what you have and how much. I happen to have a bag full of old ham radio crystals I'd be willing to trade outright for some CB crystals. Thanks! Darin

[Daniel]

I sure do but I will have to check and see what I have when i get home, it's been awhile since I looked. I believe I had maybe Channel 14,19 and 35?

 

[Daniel]

Oh forgot I posted what I previously on this thread 9,14 and 35.

 

[zeeterman]

OK Daniel, I'm interested in 9 and 35. What do you want for them sir? You can e-mail me direct at: xyzeet@gmail.com

 

[Daniel]

Sent you a email response.

 

[zeeterman]

Thanks so much for the crystals Dan! Much appreciated!

 

[Daniel]

You're welcome Darin. Hopefully they have not drifted off frequency much, but hey the price was cheap!

Anyone know of any sources other than eBay for purchasing crystals for Realistic CB?

I have several six channel mobiles I was wanting to start using.
