K3: preview of coming attractions

Administrator

Hi all,

I'm leaving Saturday for a long-planned 10-day vacation. I thought we'd
be doing another firmware update before I left. Instead, we'll give our
intrepid field testers more time with this new code, then release it
when I get back.

Here's a sneak preview. All of these features have been fully
implemented:

- transmit RF delay for slow amplifier relays
- FM mode, complete with per-band/per-memory PL tones and repeater
splits
- wider-bandwidth AM and SSB receive
- further improvements to SSB transmit, including a boost in
low-frequency response
- "absolute" S-meter alternative (reading stays the same with
preamp/attn changes)
- a variation on LIN OUT that allows recording of both RX and TX audio
- MIC+LINE IN operation for SSB contesters
- reflected-power-based KPA3 amplifier protection

Many of these have been on the short list for a long time, so we're
anxious to get this major release into your hands. Full details will be
provided in the release notes.

73,
Wayne
N6KR

Enjoy the well deserved vacation. Stay safe, es 73!

P.S. Anyone want to take any bets on whether he is taking a radio with
him?

Hi folks....

Does anyone know if this new release will address the low/slow drive power
issue when using the K3 to drive an amp in the SSB mode?

Thanks, and 73......John K4NP

Wayne,

I'm also very interested if the issue listed below is fixed.
In the last contest PEP power output in SSB mode was up and down 25%
on my Alpha 87A and the other amp.

If you mean slow response of the ALC to an audio overdrive condition,
the answer is yes. If you mean SSB output sometimes being well below the
TUNE level, the answer is yes. If you mean the power being low on the
first SSB transmission after power on, the answer is yes.

If you mean something else, please let me know and I'll try to answer :-)

73,

Lyle KK7P

Send me an Alpha 87A and I'll test it for you :-)

Seriously, the SSB peak power is much better managed in the code
currently being tested.

What about low/no output on the first transmission after a
voice keyer (DVK) message?

How about the apparent input AGC (with no user control) that makes
FP.H and FP.L behave essentially the same?
