Hello all:
I am wondering if this new model for Keurig has an SCR chopper to regulate temp
in the heater coils? Something changed...if I had one, I would take it into
the lab to figure outn what went wrong. Have full FCC EMI test
capability--could find out if they are failing in a snap! But,
Has anyone tried remote operation with a satellite internet connection? I’m
wondering if the latency is excessive.
I am looking into a remote Elecraft Station.
Thanks in advance.

and there are noise sources everywhere! Even
in the K3.
I had birdies in my Icom 781, my WJ 8711’s and my K3. They were/are all below
the atmospheric noise level. Never a problem! My PL noise was far worse.
Good topic, Bill!

Every amplifier has some level of fan noise. My new KPA1500 is seriously
quieter than my former Expert 2KFA.
My Henry 2K Ultra fans were so loud that I couldn't keep it in the radio room.
Luckily I had the remote version.
My Harris RF-3230 (all solid state) had 8 six-inch muffin fans! It
Bill Schmidt is right--you have to get rid of a bunch of heat--no matter what
device you are using to amplify (tubes, transistors, or magic). The amplifying
device must dissipate considerable heat because we are running Class AB and
because of all electronic devices are naturally lossy.

I love the backlight color on my K3/K3S and KX3. I also love my new KPA1500.
But, why oh why did you change to a blue backlight on the KPA1500? Dang, I
love that amber color--reminds me of that faded amber color of those old
radios, like my RME-45 that I had before my Novice days. Let me kno
I have traveled to Europe/Caribbean a few times with my KX3. I just packed it
in my (carry-on) suitcase or in my backpack and never had a problem. I didn't
pack it with batteries, because I could always just plug in a universal
adapter. You might choose not to bring batteries if you can get a
My KPA1500 is on its way, so my 2K-FA is for sale. Less than 6 months old,
only a few hours, 100% like new condition. Save taxes, can deliver to Dayton.

I have the SARK and have used it around the world. It works great, is
accurate, tiny, self contained and easy to use. Only downside is price but
mine has easily paid for itself (by reducing the number of times I had to climb
my tower!).

turn on that 1500 W space heater to see what this feels like!
The design is almost more of a thermodynamic challenge than an RF challenge!!!

Re: Higher Power Amps
Personally I want an amp that will load at 1500 Watts. Like my Alpha 87A or
before it my All would state RF-3230--both had loads of design margin at 1500 W
output. That give me comfort that the amp going to last a very long time.

There are several factors that make this technique insufficient to "measure"
your ears.
The K3 splits the incoming signal path and sends part of the signal to the P3
and part to the K3 receive circuitry. The split occurs just after the first
mixer so the P3 is sampling a wideband signal (+/-
For Sale: K3/100 with the following options installed:
100 W internal amplifier
KAT3 Internal Antenna Tuner
KBPF3 Bandpass filter for continuous Receive Coverage
KRX3 Second Receiver
One 2.7KHz IF filter
KIO3 Computer/Audio Interface
KXV3A Transverter Interface
KTCXO3-1 TXCO 1 ppm oscillator

I need a KIO3 to repair a K3. If you upgrade to the K3S, you have an extra.
Please make me an offer for your used KIO3.
