K3 - Possible Show Stoppers

[Joe N9VX]

I am a SSB rag-chew operator and very interested in the K3. Have had many of the rigs on the market in the last few years and like the features of the K3. I have 3 questions that may be show stoppers for me.

1. Fan noise: How loud are the fans, what rig do they compare to. In
a long SSB transmission which of the 4 speeds will be engaged? The fan noise in some rigs is not acceptable to me, like the Icom 706 or
Yaesu Mark-V 200 watt version. A lot of rigs are ok, like the IC-756 PRO, TS-870, IC-775 or Mark-V Field.

2. RF in Transmitted Audio: My shack is not in an ideal location, it
is on a second floor with my beam antenna over my head, so sometimes
I have issues with RF getting into the transmitted audio. Some
radios work fine (with some work) like Icom & Yaesu, and some have
problems like Ten-Tec. With this said, has anyone tried the K3 in a
high RF environment?

3. SSB Transmit Key-up Spikes: Some solid-state amps do not like key-
up spikes. An example, I have owned two Yaesu FT-920s and my solid-
state amp would not tolerate the key-up spikes in them.


Thanks for your answers,

What fan noise? During long runs with lots of transmitting during SS I had
to stick my hand behind the radio to see if the fans were on. They were, and
the top of the radio stayed cool. You couldn't hear them at all.

I can't answer your question about key-up spikes, but my dipole ends 25'
directly above my head and I haven't noticed any effects of RF in the
transmitted audio. I'm only running 100W so that may not mean anything.
