I just found this in a drawer in my garage. I thought this thing was long gone! Does anyone know where I can get a replacement whip for this?
Thanks,

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Any decent antenna dealer will sell you replacement whips. You probably want the Larsen 49 inch black whip.

I'll check both and see what I can find. I had a note on it, apparently from when I took it off my truck that said 46 3/4". So I'm assuming I'll need at least a 49" replacement to tune it up.
Thanks!
Thanks!

They shipped with the 49" whip if you ordered the whole enchilada. I remember on a full size truck only cutting an inch or so to get it to tune up on CB.

Yeah, this was the antenna I had on my Chevy Colorado about three years ago, before I bought the Subaru and started hugging trees. Now I have the tiny ghost antenna on the Subi for UHF, but I've been thinking about putting an 11-meter radio back in there. I do a lot of road-tripping these days. But, the old CB days aren't what they used to be so I'm still debating. Regardless, I'd like to get another whip just so I have a complete antenna.
Here is a black version and its a Larsen with free shipping. I see many other 49" whips but you would have to verify diameter at the base or drill out the whip adapter to accommodate a thicker whip.

I see you haven’t gotten out to the Bannon scale house or Tehachapi Pass as I earlier recommended. Those two are where it’s almost a guarantee you’ll hear truckers talking about conditions.
IH-15 both sides of the IH40 split is another.
All three good places to get feedback once you’ve an NRC radio and a 5’ whip antenna.
Dont expect anything much with underperforming gear unless you’re right on top of places like the above.

I wonder if you bought a 102 if you could cut it at the right diameter. And length??

Though it gives up range performance to NMO34 +W640 whip, a QT80 AM/SSB radio & DRX-901 speaker will reveal there’s more out there than first imagined.
And that it’s not so hard to talk through Skip to those nearby.
The clarity of your signal is that key. It awakens those around us. “No noise” in TX behind voice.
Plus the humor of having a big talkin’ radio in a Subaru. The association of big radio and big vehicle is fairly solid. It ain’t about power anymore.
— An air-conditioned go-kart out-talking most big trucks is funny.
A taller antenna will reveal yet more on a regular basis.
NMO34 with the W640 (64" whip) vs NMO-27 vs CWB-27
Can anyone provide data as to: Relative bandwidth between the NMO34 with the W640 (64" whip) , NMO-27 and CWB-27? Relative performance between the NMO34 with the W640 (64" whip) , NMO-27 and CWB-27? Cutting chart for NMO34 with the W640 Availability of the CWB-27?
RF/CMC choke/filters at both ends of coax ain’t wasted effort, also. In mobile it helps with both range and in keeping to shortest period being blanked by some vehicles and/or local interference.

I took a roundabout route into Ft Worth today. Unlike the usual Interstate now jammed up by a newly-started major construction project I opted to try a Farm-to-Market Road route which runs up across a rise well above the surrounding terrain (radio & radar towers).
No Skip today
I was gratified to only hear locals. And had gotten the PRESIDENT controls better dialled-in than previously. “Dead-quiet” was a mid-day pleasure.
But in the pickup I haven’t used RF/CMC chokes, in main. That’s now noted as a mistake as once I descended and came nearer to the 3-number loop I was getting killed by commercial/retail noise not obvious before and that big truck noise also covered in my previous use of this Lincoln 2+.
I wrote this as fair warning. I’m not in favor of short antennas so maybe this problem isn’t so obvious (antenna not a match to radio potential); range reduction “noise help” over a shorter travel distance versus the 7’ on the roof of mine.
— Hope you’ll try some coax noise reduction to get the most from the NMO27.
I’m quite glad to have found this new route as the change is abrupt at a particular point. It’ll be my “test zone” for metro CB use.
The same phenomenon has been true on my forays into SoCal crossing the coastal range, except that one is hemmed-in thru the pass, so it’s on the west side descent the test would be wanted.
The better antenna system vs big truck just makes 2025 environmental noise more evident, now.

I actually have a ton of type 43 beads laying round here. I probably should order some type 61 mix for 27 MHz, but I’ll for sure put something on it. I remember back in the very early nineties, our department radios got wiped out by RTD busses! The generators put out a horrid amount of noise. Our radios back then had no receive PL either, so busses, neon signs etc, we got to enjoy that a lot.

I've been playing around with a little President Bill II CB radio. It's cute and I'm planing to make it a "travel" radio by putting some power pole adapters on it and use some idustrial strength velcro to mount it. It will be used for road trips only. I'm looking forward to getting the set up completed and testing it on the road!

In the same price range, but with NRC:
CB500
It’s NRC that kicks it to next level.
When I’ve said I’ve spent a decade RX & TX in conversation with others that those right next to me in traffic couldn’t hear — it’s been mainly when rural using not-uncommon radios (mainly AM/SSB GALAXY) and a DSP speaker.
There've been reports I’ve received which not only affected my day, but did literally save lives.
It’s an impressive thing to see an Interstate get squared up by drivers once correct info is in play.
On roads with few radios (anything E-W out of California) it’s even more important. A KL-203 to go with it, obviously.
It’s not on Americas radar how much the truck driver demographic had been altered for the worse by H1B. Don’t expect an AM-19 heads-up on anything till you reach areas with local significance (ranching, etc) as part of that.
On IH-40 that means: all the way to Texas before the old normal becomes operative. That’s a very long 1,000-miles, friend. Distant Early Warning almost not functioning.
And someone like me reading you’re using a too-short antenna, low power radio, and no DSP just moves on to credible reports of what rural CB traffic is like in a particular region. That’s the frank fact of the matter, in 2025.
Upgrade when you can.
I’m glad the Subaru is getting a pair of ears. I wish I could convey how much fun it is when a little Subie is out-talking all THE BIG RIGS on an Interstate as happened one afternoon I was westbound from Fort Worth to Abilene and a retired truck driver in his Forester was King of the Road. Them oilfield hoods (379 Pete and W900 KW) weren’t happy. That old man had The Rod of God on his roof. He could hear as well as me, and that’s a feat.
I expect NOW to no longer have the advantage

A general: what should I recommend to friends who want high performance in Citizen Band? Let’s ballpark it at $500 entry. Will last longer than the time they own the automobile. Seatbelts, Concealed Carry, and CITIZEN BAND. This thread aimed at YOU, not the guy who knows even less. However...
