So Wayne, were you using a return path on your hidden mobile antenna?

I looked around just a bit. Venus was very bright and visible. But it was very difficult to look away from totality with all its beauty and uniqueness.Because of clouds, my daughter and I made a made scramble with 16 minutes to go to get to a better spot. We stopped with 4 minutes to go to totality and saw both diamond rings and 2.5 minutes of totality.As we frantically drove to this new spot, we saw a head on collision at a 4 way intersection. There was already a tow truck there. I wonder if the tow truck operator even looked up at totality.This was amazing. I've been an amateur astronomer since I was 12 years old. I tried to see the 1972 eclipse on the Gaspe peninsula in Canada but was clouded out with 2 minutes to go. I've been waiting for this one for 45 years.Carl Moreschi N4PY58 Hogwood RdLouisburg, NC 27549www.n4py.comOn 8/25/2017 4:37 PM, Rob Sherwood. rob@... [Elecraft_K3] wrote:

emotional response to seeing the corona. It was simply breathtaking.

Did the stars really come out?
Personally, I think that phenomenon would be the best to witness.

*Subject:* [Elecraft_K3] On sunspots, amplifiers, and transceivers: An
overview of the K-Line
Seeing the eclipse first-hand was amazing! I encourage everyone to get
out there and see it in 2024 if you missed this one.
This adventure also reminded me of sunspots, or lack thereof. And
where an amplifier can really make a difference. In this regard, our
new KPA1500 would make a timely addition to anyone’s arsenal.
Of course the KPA1500 and KPA500/KAT500 will work with any
transceiver. But I wanted to take a moment to explain why our other
K-Line gear (K3S, K-Pod, P3, SP3) is still your best choice in
complementing our amplifiers.
The K3S is truly an operator’s radio, in the classic sense. Virtually
every control you depend on during focussed on-air use (DXing,
contesting, etc.) is at hand in the form of a “hard” switch or knob,
right where you need it. Some high-end radios depend on the use of a
mouse and keyboard for basic control activation, or are almost
entirely controlled by deep dives through a touch screen interface.
These may not provide a satisfying ergonomic experience or adequate
response time for the serious operator.
To mention some of the specifics, the K3S has dedicated 400-count
optical encoders for both VFO A and B; a full set of message memory
and user-programmable controls; and top-level (non-menu) controls for
all common TX and RX settings as well as RIT/XIT/offset clear. There
are also rear-panel jacks for headphones and mic, allowing you to keep
the front panel area free of cables.
The K3S also has outstanding CW performance, unlike some radios that
depend on networked interfaces or suffer from computational latency.
Break-in is fast (up to 100 WPM in QRQ mode), transmitted keying
bandwidth is the cleanest in the industry, and our sidetone uses
ultra-smooth sigmoidal shaping (not a harsh square wave). It also has
unbeatable receive dynamic range (20 dB better than the closest
competitor on rejection of blocking signals). These attributes, along
with outstanding diversity receive capability, make the K3S an obvious
choice for who tackle the most difficult operating scenarios. Like,
say, 160 meter CW contests.
Finally, the K3S’s full-stereo audio (AFX mode) can dramatically
reduce operating fatigue. AFX creates a sense of space you just can’t
get with a single audio channel.
You can extend the K3S's hard controls by one 400-count optical
encoder and 16 switch functions by adding a K-Pod. The K-Pod allows
you to create your own full set of new controls in the form of macros,
allowing one-touch complex splits, etc. Many of our customers have
created clever macros that they’ve shared on our forum. Those who do
make frequent use of computer applications have told us that the K-Pod
provides just the right level of instant manual controls to supplement
their software use, minimizing effort during extended contesting.
Like the K3S, the P3 emphasizes hard controls to quickly assert
settings you use frequently, such as specific scan widths, noise
blanker or VFO B cursor on/off, pan/waterfall height selections, etc.
There are 8 user-programmable functions you can adapt to
suchrequirements. The P3’s display is also very fast, and very clean.
We’ve heard comments from those using other high-end radios that their
built-in displays often reflect evenly spaced spurs that result from
inadequate shielding of DC-to-DC converters, etc. This can’t happen
with the P3, which is separately shielded and is connected only to the
analog IF of the radio.
Besides being a ruggedly built, aesthetic complement to the K-Line,
the SP3 speaker has full-bodied sound and convenient source switching.
You can use one SP3 with two radios, or use two SP3s with two radios
when using stereo audio.
