I wonder why there is no cooling fan. I see a reasonable sized heatsink and
of course power consumption is lower without the fan.
Perhaps there is an opportunity to power an external fan from the APP

Maybe at some future date, for those using the K3 on the bench, an adapter

Jeff,
There are a number of amateurs who just do not like BNC connectors and
will not use them. In fact I have heard some comment when looking at a
K2/10 say "That antenna connector MUST be changed to a UHF type". While
I do not agree, it is a perception that must be dealt with at Elecraft.

Tim,
All Elecraft QRP level gear uses BNC connectors. The 100 watt class
amplifiers and tuners use UHF connectors.
Yes, the QRP community has adopted BNC connectors as "standard".
Elecraft adheres to that.

Engineering perspective? I'm an MSEE, have been working with BNC connectors for
thirty years and I don't have issue with their use on HF radio gear. If they're
good enough for Agilent, Rohde and Schwarz, Anritsu, et al, they're good enough
for a 10W HF transceiver.

UHF connectors are embarrassing. They are obsolete and only used on ham and CB

Not only is it too easy to damage the center pin/socket, BNC is a
"clamp" type connector and is prone to improper assembly. Having
"grown up" with Heathkit, I would rather have RCA connectors - the

I can think of one other reason why UHF has hung around so long. It is cheap,
easy to find, and mates nicely with the oh so common RG-8 sized cable that is
generally used in HF shacks. N would probably be a better choice but is more
expensive and fussier to install. BNC connectors for RG-8 do

David - Those are very good reasons to keep UHF connectors.
The impendence mismatch of UHF is probably far less than the other

With the combination of DUAL RX and NR or Autonotch, you may have loss of
audio, see "DSPT" (DSP timeout) or "ERR DSX" (DSP communications error).
Turning the radio off/on will clear any of these conditions. This can happen
when turning the controls on or off, or on exit from an ATU tune, etc.
