[Elecraft] KX3 Heat Sink

2017-08-05 Thread w4sc
Hi Jim,

I purchased the PRO-Audio KX31 heat sink for my KX3.

After looking at the available designs at the time, the choices were narrowed 
to two. The KX31, and VE7 designs.  The larger ultimate KX32 and VE7,nor the 
improved Elecraft designs were available at the time.

The deciding reason I chose the KX31 over the available VE7 design was 
aesthetic.  I liked the “rounding over” of the dissipating fins and that the 
tool access to the mounting screws were on centers that did not cut through any 
fins.  The differences between the cost negligible, and performance, are 
extremely small.

Re: [Elecraft] KX3 Heat Sink

Hi Jim,

I recently purchased my KX3 and intend on doing a lot of digital modes.  
I looked into 3rd party heatsinks, but was notified that Elecraft uses a 
new improved heatsink that wraps around the bottom of the KX3.


So my question to you is, do you have the newer KX3 Elecraft heatsink or 
the older model?  I was going to work mine first to see how hot it gets 
before making a move if the newer heatsink is acceptable.   I can't find 
any reviews of it.


I will definitely be watching this thread to figure out if I too want to 
purchase the 3rd party Pro Audio Engineering KX32 Ultimate Heatsink as a 
replacement.

Re: [Elecraft] KX3 Heat Sink

2017-08-04 Thread k2ud
Of all of the aftermarket KX3 heatsinks, the VE7FMN has the most surface area 
and mass- read that, it will be the coolest albiet heaviest heatsink you can 
add to the rig.  I have one on mine, run RTTY and PSK31 a lot and never notice 
much in the way of heat at all with the heatsink.

Look at http://VE7FMN.CA for more info.

heat sink addition will impact Rose's covers or cases and Scott's end
plates or front cover.  Can you confirm?

A photo on the website might save the staff time in the long run. (:-)

[Elecraft] KX3 Heat Sink Improved and Now Shipping -- Easy Retrofit to Existing KX3's

2014-12-29 Thread Wayne Burdick
Hi all,

In response to feedback from KX3 users, we have improved the transceiver's heat 
sink, without significantly changing its outside dimensions. The new heat sink 
has twice the surface area and much greater mass, using an 'L' configuration 
that places part of the heat sink underneath the rig's chassis. A 
high-performance, die-cut thermal gasket is used between the rear panel and 
heat sink to ensure excellent heat transfer. 

Our lab tests show that for a given power output level, the new heat sink 
provides up to twice as much transmit time as the original before power is 
automatically scaled back under firmware control. 

(Larger, third-party heat sinks can still be used, if desired, to allow 
extended operation in data modes at full power, or at very high ambient 
temperatures.)

The new heat sink is already included in production KX3s, starting with S/N 
7292 for kits, and S/N 7255 for factory assembled units. It can be easily added 
to existing KX3s using modification kit model #KX3HSKIT ($39.95). Refer to our 
Spare Parts and Mod Kits page, KX3 section:

  http://www.elecraft.com/order_form_parts.htm#kx3

If demand is high for modification kits, there may be a brief delay in filling 
orders.

73,
Wayne

[Elecraft] KX3 heat sink

2014-06-24 Thread Johnny Siu
Hello elecrafters,

I have recently purchased a KX3 heat sink from John KB8UHN.  Product is very 
nice and well fit to my KX3.  The price was about USD40.  His contact is good 
at http://www.qrz.com/ 

I have no business connection with him but am just a happy user.  For details, 
could you please contact him direct?  You may also wish to advise him whether 
you are going to install the Side KK panel as well so that the heat sink will 
well fit the dimension.

Just a piece of information to the group and I do not want to be involved in 
any business debates.

[Elecraft] KX3 Heat sink from Fred Meier, VE7FMN

2014-04-04 Thread T Gahagan
Received Fred’s heat sink yesterday and installed it on the KX3 today.  
Beautifully done and fits like a glove. It took about 10 minutes to install and 
the powder coat finish matches the radio nicely, and all covers still fit 
nicely.  Thank for a great job Fred.  Now I’ll try to do some thermal testing 
over the next several days.

Todd, WA7U

Check out my listings on eBay for my new heat sinks with engraved
callsign.  Just do a search for "kx3 heat sink".   They will also be
available without callsign soon.  Thanks  Gary, N8WTT
