What causes the key bounce problem? Is it mechanical or electronic?

How can I find out?

Probably by opening the whole thing up I guess I opened it up for the
entry to the IC10 ICs, but unsure whether I want to take that much
further, as I'm not *that* experienced with electronics. Certainly dont
want to risk damaging the rx.

I can live with it as it is now, and soon I will control the rx from my
PC anyway.

From what the people on the R-5000 Yahoo group have said it's mechanical.

The similar to the problems that cheap remote controls get.

I wouldn't take it apart if you don't have too. I've had success with
modifying the keys on a Drake-SW8 to make them more reliable. The SW8
keys can be erratic if you don't push them exactly in the center. I had
to add some thin silicone shims under each key to reduce the amount of
wobbling. That's what causes the keys to sometimes not accept an entry
when they're pushed. I would imagine the keys on the R5000 are a
different design.

That was one of my first impressions of dedicated communications
speakers, due to first tests typically done on easily available strong
stations. But when you really try to dig out something weak and scrape
some of the noise off it is when the audio characteristics of those
communications speakers is really appreciated.
In my case I have a couple HAM rigs that can double for SWLing and the
one with the bigger acoustic suspension bookshelf speaker sounds much
easier to listen to for extended periods on strong SW and AMBCB talk
shows etc. whereas the one with the communications grade speaker is far
easier to use for pulling enough syllables out of the hash to confirm a
contact.

I have a Kenwood TS-2000 that has a KLH speaker on it and it sounds
great on V/UHF-FM repeaters or just some Mariachi from a Tijuana AMBCB
station, but the Icom 756-Pro3 fitted to an SP-23 is the much better
setup for digging out a 17m contact thats plagued with QRN & QSB.
Of course for the sheer convenience and performance on routine
reception, the E1 gets top honors. Not so many knobs to adjust yet
excellent sound, at least when the ambient noise level is low.

DX - When You Need Head-Phones To Hear It . . .
What's On Your Head ? ? ? and In-Your-Ears ! ! !

Yes one of the Speakers from a set of Stereo "Book Shielf"
Speakers can be used for good for Easy Listening with
many Radio/Receivers -but- Ffor Digging-Out the those
Hard-to-Hear Sounds of DX Audio Dirt Diving it comes down
to one compound words : "Head-Phones" {Headphones}

Yes "Headphones" - They 'focus' your hearing on the Sounds
coming out of a Radio/Receiver and Block most of the Exterior
Sounds in your Audio Environment.

Not just any Headphones -but- Good Communications 'Quality'
Headphones that are designed to reproduce the Frequency
Natural Range of the Human Voice and attinuate the other
Sounds and Noises that you are not interested in hearing.

Please don't used common Music Stereo Listening Headphones
for DXing in the Dirt on your Radio/Receiver : There are about as
good as the Stereo Speakers and will let you HEAR every Sound
and Noise coming out of the Radio/Receiver.

Here is a Sample of some 'good' Radio/Receiver Listening
Headphones and my 'opinion' of them for Radio DXing :
http://www.universal-radio.com/catalog/head.html
* Heil QUIET PHONES
http://www.grove-ent.com/HEILHDP.html
Nice and Feature Noise Cancelling
* ICOM HP-4 Mono
Basic but Effective
* Japan Radio ST-3 Mono
Nice Comfort and Fit but a bit to bright.
* * Kenwood HS-5 Mono
My 'choice' for Sound, Comfort and Fit
* Kenwood HS-6 Mono
Light Weight and will do for a Travel Radio
set of Headphones.
* Pyramid HP-30 Stereo
More for Music than DXing
* Sony MDR Stereo
Great for Walkman 'type' FM Stereo Listening
* Vanco HF-24RS Mono
Value and Priced
* Yaesu YH-77STA Stereo
Light Weight and will do for an all around
Travel Radio set of Headphones.

The second hand r5000 that I got last week suffers a bit from the key

Funny, I use the big round thing on the front to change stations,

The only time I use the keys is to change mode.

For One and All,

Here are My Three Reasons to Own a Kenwood R-5000 Receiver :
http://groups.yahoo.com/group/kenwoo...0/message/2110
* "The Sound"
* The "Feel-and-Beauty" of it's Tuning
* Plus Solid Performance and Reliability

Yes the Kenwood R-5000 Receiver's Tuning Knob has
'that-feel' to it that makes it enjoyable to Tune
within the Band. Plus there are the 1-MHz-Up and
1-MHz-Down Buttons just to the bottom right of the
Tuning Knob that makes Changing-Bands real easy
and fast. Also using the Memories as the Starting
Points of the Amateur or Shortwave Bands can be
a big help in going Up-and-Down the Bands with the
Buttons and then using the Tuning Knob to Seek-Out
what Out-There on that Band.

I guess I am a Tuning Knob 'person' cause using it
allows me to "Find-What's-Out-There" {DISCOVERY}
vice relying on a pre-programmed Memory or Keying-In
a Specific Frequency to go to a 'known' Station.
About - 80% Tuning Knob -vice- 20% Keys-and-Memory.

This is 'Why' I have kept the Kenwood R-5000 Receiver
over the Years is "The Sound" and the "Feel-and-Beauty"
of it's Tuning; plus Solid Perfromance and Reliability.

My Kenwood R-5000 Receivers have the 'optional'
IF Filters :
* 6 kHz AM Filter
* 2.4 kHz Wide-SSB Filter
* 1.8 kHz Narrow-SSB Filter
http://ph.groups.yahoo.com/group/ken.../view/b4af?b=9

FWIW - The INRAD 6kHz AM Filter is an 'alternative'
to the 'optional' Kenwood 6 kHz AM Filter that many
Kenwood R-5000 Receiver Owner's like to use.
http://ph.groups.yahoo.com/group/ken...view/b4af?b=11

IIRC - There is another Kenwood IF Filter that is design
for one of their Transcevers that is Listed as a YK-88S-1
and is a Drop-In for the Kenwood R-5000 Receiver however
it is rated as 2.8 or 3.2 kHz Wide-SSB Filter.
- - - I would like to find one and try it.
? Any One Know {Info Please} about this 'other' YK-88S-1 ?


some say - i would if i could . . .
i simply say 'kenwood' ~ RHF

Awwww,,, I am fixin to go see what them yeyhooos at
alt.gossip.celebrities are squawikin aboot now.M*A*S*H is on Radio tb

Be aware that r5000's can vary in price due to optionals added into the
radio. They can be a VHF convertor unit, and a range of optional
filters. They can greatly affect the price of second hand r5000's.
The options that are available a

1. Replacment AM filter. Kenwood's was also 6kHz, but much more selective.
Other companies also had direct replacements and International Crystal
had/has a 4kHz filter.

2. Narrow SSB filter 1.8kHz.

3. Narrow CW filter 600/500/250 kHz, I think Kenwood's were 500 and 250.

4. Computer control. 2 chips added under front panel, TTL to RS232 converter
in the cable. Real old units need a ROM upgrade too. Chips and cables
can be obtained from third parties.

5. Voice sythesiser. Very rare,

6. VHF converter. Rare and expensive.

7. Car Kit. Adds a 12 volt power socket in the back, came with a detachable
cable.

Good list of the options. The optional filters are certainly worth
looking for. The VHF converter has become a collectible and the price
seems excessive in light of its limited coverage. The computer
control board is worth looking for IF remote control is wanted. The
other options don't seem to command much of a premium in price.


Other issues:

PLL unlock aka the dreaded dots problem. Due to poor choice of manufacturing
materials, the main PLL unlocks, the display shows only dots.

Memory battery. A 3 volt RECHARGEABLE lithium battery under the front cover.
eventualy needs replacing.

The keyboard bounce problem others have noted.

Note that early units sold in the U.S. were 120 volt only. Mine purchased
in 1990 was, by 1993 they were replaced with a multivoltage (manualy
switched) unit.

In plain English a unit with no additional filters (6kHz AM wide, 2.4kHz SSB),
and no other add ons, that has never had the battery replaced or the PPL
unlock fixed is worth around $200-$250 dollars. It is very likely both
will have to be done.

A unit with ALL accesories (narrow AM replacement, add on narrow SSB and CW
filters), recent battery replacment and PLL fix, computer interface,
voice sythesiser and VHF converter could easily go for close to $1000.
(and be worth it IMHO).

Figure the VHF convertor is worth $150-$200 if you want one, the
filters are worth $50 each. There were never enough voice sythesisers
to set a price. The 12v car kit is not worth much, and the computer
interface is not a high demand item.

Note that with today's prices, it's cheaper to buy a used R-5000 with a
VHF converter, keep the better of the two and sell the other than to buy
one on it's own and put it in the radio you have.

Geoff.

Nice list of the R5000 issues.


Another R5000 design issue that's overlooked is the extremely hot
running 110V PS in it. Running the radio on 12V is a very smart move.
I operated an R5000 for several years and never noted it running extremely hot.

dxAce
Michigan
USA




The two regs that got insanely hot were inside the radio, when/if they
failed, it was a 250 buck repair. I know, I paid to have a tech fix it.
The outside only gets moderately warm, to slightly hot. The slightest
amount of air blowing on the outside cooled it down nicely. On the
outside. Touching those regs when it was running would get your fingers
burned.

I had an Icom R-7100 that was another one that ran insanely hot. It made
a great space heater on 120V. On 12V, it was nice and cool.


BDK


True of R70, R71, and R7000 as well.






I didn't have the R70 here long enough to notice, but the two R71's I
had didn't run nearly as hot as the 7100 did. I had the one R71 apart
for several days trying to find the cold/cracked solder joint that made
the signal strength go up and down, and I touched about everything
inside it. I finally found it, and like almost always, it was where a
plug was soldered into a PC board. I found another one on the same plug.

I'm not a Dx'er, I'm mostly into Utes, but I can only take headphones
for about an hour or so, and I'm done.

I have the JRC ST-3 and both the Kenwood phones, along with the Yaesu
ones and all of them sit in the boxes. I should just ebay them.

The cans I've got are Stereo Music Listening style Koss UR-40http://tinyurl.com/ymjeggbought from Radio Shack, but I plug them into
the jack on an SP-23 which provides enough customizable audio filtration
to whack off the ultra highs and lows.http://tinyurl.com/ymqo78
I've tried the RS noise canceling ones as well as Heil Quiet Phones,
neither of which had as pleasant sound as when the canceling was
switched off, but behind the SP-23 almost any cans do well.
