HK Radio Removal

[Schmoe]

AMEX is on the bar, use it or lose it.

I've had 2 radio issues over the past year and finally got around to fixing
them or at least trying to. Main issue is the AUX jack was cutting out on
the right speaker so I removed it and sent it to Iron Cross Radio in New
Joisey for a repair of the jack and install of a rear mounted jack so I
could permanently hide the wire. The repaired unit came back quickly BUTT
while the front jack is now working correctly, the new rear mounted jack is
cutting out. So I've got to send the radio back again. Here's my question.
Removing the radio mount screws is a major PITA because they are on the
inside of the bracket and very difficult to reach. I used a standard right
angle Allen wrench but it's a slow PITA process getting those screws out.
Anyone know the way or tool to use?

Second, the radio antenna cable got completely crimped near the steering
fork. Rather than replace the entire cable, I bought a marine use connector.
It's looks like this:

The center wire seems like it wouldn't make a good contact while the crimp
ground outside legs are pressed into the rubber shield to puncture and
contact the ground wires. After installing, the radio is working better but
the reception is not great making me think the contact isn't good.
Suggestions? I'd hate to have to run a completely new cable but will if it
comes to that.

Thanks. If you made it through this, there's a cold SNPA tap waiting on this
side.

This is a link to a Harbor Freight page. The set shown is metric, but
the SAE version looks the same. The ball on the end lets you get at it
from an angle. Handier than a pocket on a shirt! I use 'em to get my
radio in and out.

Funny you mention it, cuz today I was in the NAPA store and bought
another set of SAE ball end hex keys. NAPA has a sale on their tools
right now. Don't know if it is a nation-wide sale or not, but it might
be a good time to stock up on tools. Like the old saying goes, "Too many
tools aren't enough."

Getting the screw rolled in a couple turns or out the last turn or 2 isn't
the slow part. Wouldn't grease on the ball end make it hard to turn?

Only if it is *synthetic* grease.
To slippery, you know?

Everyone knows that dino grease is best for putting on a wrench. Sheesh!
Putting synthetic grease on a Craftsman tool, for instance, voids their
replacement warranty.

P.S. The real solution is to buy the magnetic ball end hex keys.

Heh heh.

I had the same problem removing my radio, and as I think someone
pointed out, the only way to do it is with a ball end Allen wrench.
Still, it's a slow process!

Your antenna:
When I put my Tour-Pak on my Street Glide, the stock antenna got in
the way. Rather than relocate it, I also tried a few different
versions. I tried one that was small enough to fit underneath, as
well as an antenna that fit inside the fairing.
They all worked, but I couldn't find anything that worked as well as
the stock antenna. A guy I know who's a really smart Electrical
Engineer told me that antennas are usually matched to work with the
specific impedance of a radio, (I have no idea what that means!), and
that sometimes, (not always), it's difficult to replace an antenna and
get the same performance. That was my experience, and I ended up
relocating it with the relo kit.

Speakers are matched to the impedance of the radio amplifier's output.

http://www.prestonelectronics.com/audio/Impedance.htm


Antennas are cut to the median bandwidth, or fraction thereof, that
the receiver can be tuned to. Antennas can also be artificially
shortened or lengthened with resisters (Loading coils) and capacitors.

A transmitter's antenna must be tuned to a full wave length, 1/2, or
quarter, to achieve the proper standing wave ratio and not burn up the
xmitter with an improper load.

I guessing you may have misunderstood the engineer if he discussed
both antennas and speakers with you.

I don't believe any of the theory has changed since I went to school.
But I've been accused of being wrong before. <sfsf>

Those changes affect the impedance. The antenna and any matching network
need to be as close to the input impedance of the receiver as possible
for maximum transfer of signal into the receiver. The antenna is cut to
the median frequency, as you stated, to provide optimum coverage
throughout the band. If you cut it for the top of the band, say 1610 KHz
on AM, then the lower end near 520 KHz won't receive as well, and
vice-versa. Not as critical on AM broadcast but more so on FM. Really
critical on CB because you're not only receiving, you're transmitting
and you want as much of the transmitted power to leave the antenna as
possible. Too much of a mismatch and the power is reflected back to the
radio, which can damage it.

The Harley receive antenna is designed to operate on AM, FM, and the
weather channels and has set tuning components. That specific length
presents a certain impedance at certain frequencies. You swap that out
for a shorter antenna and you're no longer presenting the right
impedance to the radio. Some of the better aftermarket antennas have
been designed to mimic the length of the stock antenna.

Most AM receivers I have dealt with are pretty happy with anything from
a wet noodle to a full wave wire.

I don't know if Harley has incorporated some sort of matching network in
their antenna system that requires a critical length of whip.

Receiver antenna circuits are not nearly as critical as transmitter
antenna circuits although the better the "match" between the antenna and
the receiver, the better the overall performance.

I agree, too much of a mismatch and there is potential for equipment
damage, but most transmitters these days have automatic foldback to
prevent damage in the event of high VSWR. A friend of mine is the Chief
Engineer for the Public Radio AM and FM transmitters in western
Virginia. He lost his main transmitter which was running 100kw ERP (I
am guessing 25-50kw out of the box), when a feedline flange arced. The
transmitter sustained no damage.

Very good. Now lets talk velocity factors of coax and coax length.

You do any HF work? Only mobile antennas at the moment, 10, 20 and
40. Was thinkin of a flag pole vertical.

HF SSB is all I do. Turn on 2m occasionally, get my fill of the bs, then
turn it back off.

Running a 66' doublet and a 40' homebrew vertical. Elecraft K3 and an
Ameritron AL-811 amp.

Ham sticks for 10, 20, 40. A stock 706MkII I have a couple of beams
in storage in WI. A cushcraft complete triband, A cushcraft for
parts. A KLM 34XA 4 ele tribander. And another I can't think of the
name. I also have a 11 meter big gun that I cut for ten and it works
great! I brought wire and a tuner down here but don't really have
anything to hang it on in the park where I live. I used to be into AM
and have lots of transmitters and a couple of receivers. I also have
a Johnson Kilowatt transmitter that works very well! Lots of tubes
and parts including extra transmitters for parts...About 1200 pounds
of it!! All of it in WI.
