[Elecraft] K4 Remote Software?

[Gerry Hull]

Hi Jim,

I've been doing remote ham radio in serious contest stations for about 10
years now...

Though is wasn't me, the guys at ZF1A achieved a 433-QSO-per hour CW rate
on remote, using a K3 and Microbit RRC boxes.  On non-ideal Internet paths,
I typically reach 175+ hour rates on CW.  This is not to brag -- it is to
illusttate that overall latency in Internet remote operation is really not
a factor in well-designed systems.  Like you say, Jim, there are many
things that contribute to overall latency.

In a previous life, i worked in broadcast TV video and audio systems, on
the Windows platform.  Audio latency was there, but mitigated by proper
techniques.


The so-called, self-proclaimed "leader" in remote amateur radiio systems
has serious problems with latency   -- so bad that I've had to resort to
using third-party, open source audio software with very low latency to
overcome issues.

As of today, the combo of the K3s + Mirobit RRC boxes rocks the remote
world.  That's not just my humble opinion, its a proven fact via results.
In fact, many bypass the audio built into other systems and use RRC boxes
to mitigate these issues.

I'm just hoping the excellent Elecraft engineering team can approach the
same level of performance in the V4 remote.

73,
