Hi:

Although the Mocom 70 Base Consolette was a good
radio in its time period ( 70's ) , its truly not worth the
investment when you can get a programmable
radio, and it does not take 2 men to move it.

i need to get Xtals for it...and i want to get 4 channels TX and RX
where can i find them?

The Mocom70 Consolette requires the use of channel
elements, and the crystals go inside of them. If you are
speaking of having 4 complete and seperate
channels, you will be needing 8 Channel elements
" Recrystaled " @ approx 15.00ea, you are looking
at $ 120.00 just in Crysatls.

and what is the range of a 40 watt radio compared in miles?

Your radio is only spec'ed @ 25 Watts for the 33 series.

This all depends on terrain.......Good average is about 5 ~ 10 Miles

i want to get the VHF MURS freqs...

154.6000
154.5700

and i can not remember the other 2 in the 151 range...please let me know if anyone can help me with this

CU33BBA-1000A

This generally means the radio is " Carrier Squelch " unless someone has added a tone dech over the years.
SERIAL # T006 CU

it is set for 161.1700 and i want to get the new Xtals for it...thanks alot

So, unless you can find someone with Channel Elements already
on your freq ( which I would find rare ) its going to cost you several
bucks in parts, and the " Labor " to re-alighn the whole radio.

They are " Not Wide-Band " Radios, and moving the radio from
the 161 Mhz range to 151 Mhz, and trying to stagger tune the
radio to work in the 154 Mhz range could easily cost another
50.00 ~ 100.00 unless you have someone in your area willing
to due it as a favor

It could easily run 200.00 ~ 300.00 by the time you are
finished.

I use to set these radios up all the time, many are still in use
today, but truly not a practical approch for a 25 watt radio
when one can find a 16 Channel Maxtrac for 150.00 ~ 300.00 depending on options and accessories.

Hate to be the bearer of bad news, , but that is where
the market is today !

Not to pile on, but the MURS freqs the max power is 2W ERP.

You have to concider where this request for information is coming from. Once you see the username, it will all make perfect sense.

the 151Mhz freqs are also narrow bandwidth if i remember correctly.

And I thought I was crazy messing with MT500's and HT220's all the time.

I shouldn't talk though, I've got some Motracs that I'm trying to get to work.

You'd need one helluva power supply to run that thing, and lot of $$$ for elements, aligning, and parts for it if you can find 'em. I'd say to just get a Maxtrac like Monty said and run that as a base.

A local friend decided he had to put his old Mocom70 on a couple of the UHF amateur frequencies. Only God knows why, but he just had to put that thing on the air. He spent $100+ on channel elements, and he got about 30 watts output from it. With the money he put in to it he could have purchased a nice synthesized radio that would do so much more. But he loves those old commercial rigs (even though it's really an old piece of junk). I guess he sleeps better at night knowing he's using that old Mocom70. I wouldn't put a dime into that thing if it were me, but he would spend hundreds if that's what it took (which actually did with all costs included). No one here understands that kind of thinking, but he's that way if you know what I mean . . .

What can I say? Some people just love that really old stuff, even if it costs more to put it on the air than buying a new radio would. Whatever.

Not to mention that a C33BBA1000A was a single freq unit. So now more $ have to be spent to bring up the other three.
