Very interesting. Thank you.

Havis has brackets to attach one of their floor plates to the bracket around the RCM. I've been considering going that route, but have some concerns about the stability of that arrangement. For one, there's nothing anchoring the floor plate to the transmission tunnel ...

I have a new F-150 and I'm looking for console ideas. Do you have photos of this wiring chase?

Thanks for the cross-reference.

What impedance is the HSN8145? 4 or 8 ohms?

In another thread, we got to talking about small external speakers that still sound good. While sorting through a junk box yesterday, I found a new-in-the-box sample of one of the speakers I've been happy with. I bought it at a hamfest several years ago.

It appears to have been part of a Motorola ...

I have some speakers like the KES-3 and they do pretty well. Some of them I thought came from old Motorola cellphone car kits. I'd like to find a couple more as the smaller ones are crap.

I have been sorely disappointed with the small external speakers I've been seeing at hamfests. They must be building these things with high frequency drivers because they sound very tinny to my ears. Unfortunately, this seems to be an area where ...

Thanks for the replies and suggestions. I'm going to go with a Larsen NMO50 or something similar mounted at pretty much the center of the roof in both directions. The hole was drilled, the mount installed, and the feedline routed last weekend. Maybe this weekend, I'll get the antenna mounted and ...

The county where I live is developing plans for a new Emergency Operations Center. I suggested to the EMA Director that the new EOC should have provisions for amateur radio. He contacted the "owner" of the building where the new EOC is going and we have an agreement in principle to mount an antenna ...

I'm considering various antenna options for 6m FM and I'd like the group's opinions. The vehicle in quesiton is a Ford Expedition so it has lots of roof surface and I'm not concerned about drilling holes.

Here's what I see as possibilities:

1. A full-size quarter-wave on a ...

"...They have called ahead by now and you can't outrun a MOTOROLA". Great line from Dan Aykroyd!
And the obvious tie-in there is that the movie was based in Chicago and Motorola is headquartered in Schaumburg, a Chicago suburb. Just another example of great writing from a great movie.

Correct! There's another ISO hole, perfect for ISO size radio's.
Ed, since the 2002 model year, U.S.-spec Golfs, Jettas, and GTIs with the upgraded audio system ("Monsoon") have had a "dual DIN" head unit that works with the included power amp and also controls the optional 6-disc CD changer. This ...

No, I bought an A4 GTI a few months before the new ones hit the dealers. My 1.8T is rated at 180HP while the 2.0T in the new ones is rated at 200HP. The weights are comparable, I think, so the new ones should be a little faster than mine. The new ones are also reported to handle better, but with a ...

K4RXR

I can't give you any real experience, just some observations. I owned a 2002 Jetta 1.8T and now a 2005 GTI 1.8T.

In the 2002 model, the "cupholder" was a thingie that popped out of the dash above the radio. Sometime between then and my 2005, they redesigned the console to move the cupholder down ...

On second thought, and after doing some Googling, maybe I didn't see what I thought I saw.

Take a look at this photo http://home.comcast.net/~buck0/app_asb3.jpg. Maybe that's what I saw, because I can't recall ever seeing a tie-wrap small enough to go through the "roll-pin" holes.

I've been a little disappointed in the mating friction of the Powerpoles.
At Dayton, I couldn't help but notice that one of the Powerpole dealers had kinda solved the lack of pull-apart resistance. You know how when you slide two connector shells together, there's a small hole on the split line of ...

Does the vehicle have a roof-mounted luggage rack? Both Diamond and Comet make NMO mounts that will attach to the rails of a luggage rack.

K4RXR

After much personal reflection, I recall that I owned a Comet SBB-2NMO for a while. It was mounted on the luggage rack on my Ford Explorer using a Diamond mount of some sort. I forgot the antenna was there one day and put the Exploder in the garage. Snapped that Comet right off. The ferrule where ...

Tom, any chance you could post one or two photos here? I'm looking for mounting ideas for my Volkswagen GTI.

Thanks!

It's still physically too short for a full 1/4 wave on VHF. How much radiated signal is getting converted to heat in whatever coil thingy is at the bottom of the antenna?

As an alternative, take a look at the Comet SBB-2NMO. 18" long, 2.15dBi on 146MHz, 3.8dBi on 446MHz. I used to think that Comet ...

Make absolutely certain that you have the repeater tuned before you even think of putting it on the air. The TKR-x50 series has a real front end/preselector in it... if you don't tune it for your specific frequencies, your sensitivity will suck.
Yeah, and that may be the issue. The shop probably ...

K4RXR

OK, thanks. Based on what I'm seeing on 911EP's web site, it may have been the LS12.

I noticed a local county sheriff department CVPI with a very eye-catching warning light. It was about 18" long and mounted on top of the dashboard at the base of the windshield. Half of the light was red, other half blue, appeared to be LEDs. The light was programmed so that the LEDs seemed to be ...

I see a couple of you guys bragging on the Kenwood TKR-750 for ham use. What about the TKR-850 in the ham bands (447 in, 442 out)? A local Kenwood shop said it couldn't be done.

Do a Google search for Windows Help Compiler. The actual compiler from Microsoft ships with their development products (Visual Basic, C, etc.). There may be a freeware/shareware/public license compiler out there, but I didn't look that far.

And with all due respect to Gary, in my opinion, Jotto is just downright dangerous. Cheap would be the word I'd use. We won't compromise anyone's safety to save some $$.

In the case of the software for the Kenwood TK-x90 mobiles, the DOS version is readily available and seems to run OK on most computers, though I'm guessing that it won't talk to the radio if run in a DOS box under Windows. It's probably best to boot the computer straight to DOS. The Windows version ...

I have a SanDisk Cruzer Micro 1GB USB flash drive that I bought at BestBuy last November for about $80. The thing worked great. Even though the U3 software that's supposed to let you run programs from the flash drive was kind of annoying at times, the drive had tons of room and always worked ...

Thanks for all of the tips and advice.

Note that I said nothing in my original post about fusing the ground lead. My question was whether or not to ground to the body/chassis of the vehicle at the equipment or run the grounds back to the underhood electrical distribution point. Based on what I read ...

K4RXR

At the risk of opening the great power wiring debates again, I have some questions for the group:

1. When mounting radio equipment in a vehicle, is it better to do the grounding at the equipment or run the grounds back to the power source? Let's say you are tapping off the battery or other reliable ...

What are these systems using for an extinguishing agent? Halon is probably the best, but it's a chlorinated fluorohydrocarbon, so production has been seriously curtailed by federal and international regulations.

I ordered some Larsen NMOKHFDS mounts from Tessco earlier this week. No account necessary if you use a credit card. The DS cable is essentially the same as the UD cable, but uses a stranded center conductor.

Also, you should be able to find dielectric grease at just about any auto parts store (NAPA ...

Take a look at the Jotto Desk console. If you think it will suit your needs, let me know. I have one that I took out of an '03 Exploder. It fit great and was easy to install, but I ended up getting rid of the car. I'll sell the console and some face plates for less than new price. You can email me ...

I think I have it figured out. The link to the installation instructions on Jotto Desk's website was broken, but it worked today when I checked. It looks like once you remove the screw that's under the pad in the storage compartment, it's just a matter of applying some pressure to pop the top out of ...
