I need to know how to add a port to support WSJT operation with a K3 controlled by a K3/0 and Remote Rig units

David Mackey
 

I currently have a K3 & K3/0 operating via RRC units on SSB & CW. Want to add WSJT capability which requires a PC for WSJT at the remote (radio) site to have local control of the radio and provide a waterfall display and interactive control. The PC is installed and accessible at the control site via a virtual PC application. The problem is the CAT control of the radio from the WSJT aplication on the Radio site PC. There appears to be only one port available which does not work. How do I enable a port between the radio PC and the radio, so as not to effect the normal remote control operation.

Re: [Elecraft_K3] Re: Now accepting orders for the Elecraft KPA1500 amplifier

Steve,

The BIG difference is the Elecraft is 1500W out with 100% duty cycle (1500 W out RTTY).  The Expert linear will not allow 1500W out key down.

I had looked into the Expert amp last year, and its power output did not meet my requirements

Wayne,

Can you elaborate more specifically on filtering and harmonic suppression per band?  Sure, we assume the device meets FCC specs.  But for an SO2R station, a lot more is relevant.  Some other designs go further than typical low pass filters in order to  better support the needs of SO2R and provide really good harmonic supression.

Since you are now taking orders, it seems appropriate to ask for this sort of data.  We all love Elecraft, but I want to make an informed decision and the lack of SO2R capability built into the amplifier makes me wonder how much these issues were considered.

Our low-pass filtering is more than sufficient to meet FCC approval. Filter order varies a bit depending on the band. We’ve done extensive testing, both electrical and thermal, and I’ve seen no evidence of unusual odd-harmonic behavior. Seems rather tame, actually.

Bruce Prior
 

The fun part for me was watching the reactions of our son, daughter and two granddaughters to the total eclipse. We found what we thought might be an isolated site -- a hill north of Arco ID. Only about 30 people were there! After totality almost all of them joined in an effort to collect broken glass and other debris from who-knows-how-many drunken parties there. So much was collected in a heavy-duty trash-bag that it was hard to carry! It's heartening when a group of mostly-strangers pitch in on a community project!


This ass the second total eclipse that I've seen, and I'd love to see another. In Arco a group affiliated with NASA launched a high-altitude balloon, one of about 50 deployed along the totality path. I'm looking forward to seeing lots of eclipse video productions online and on television.


Margaret K7MWP elected to stay in the temporary campground at Butte County Fair for the eclipse. She had fun photographing the weird tree shadows during the partial phases. People all over North America and beyond had a chance to experience those. We had no trees on the hilltop. Trying to peer into a sun-filter-equipped telescope low to the ground on the hill I tumbled over, getting into an argument with some sort of spiny desert plant. Margaret worked for a long time with tweezers, but I still have some souvenirs left over!

*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.

K3S:

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.

K-Pod:

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.

P3:

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.

SP3:

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.

product, feel free to contact us.

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.

K3S:

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.

K-Pod:

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.

P3:

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.

SP3:

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.
