No. There were the usual show special deals and the KPA1500 was
emphasized. The whole conference, including the vendor area, was
fairly low key, with nothing new and earth shattering.

Out of curiosity. did Flex Radio Systems tout their new SmartSDR v3,0.19 featuring “multiFlex” that allows two operators to share one Flex-6xxx series transceiver (or one operator use two devices such as a laptop with SmartSDR and a Maestro connected to the same transceiver at the same time)?  Given the focus on DX and contesting at Visalia, I’m wondering what the crowd reaction might have been to this newly released capability?  

I suspect that while this is a technical achievement, non-contest users are being challenged to determine how exactly multiFLEX works and what advantages it brings to their operating experience.  However, there appears to be significant benefits to multi operator contest stations as well as single operator two radio (SO2R) setups, reducing the number of transceivers and associated control boxes/cabling while allowing both two operations using the same transceiver to share the same antenna.

I also suspect that what is driving Flex’s focus on the needs of contest operations is that contest stations spend ‘real money’ on equipment and software to enhance their competitive advantage. It’ll be interesting to see whether the evolution of technology by Flex using SDR will translate to tangible benefits for the "rest of us” as well as whether other equipment manufacturers respond to these technical enhancements.

In reply to this post by Elecraft mailing list
I didn't spend any time at the Flex booth, although their signas
touted SmartSDR Version 3, so I expect they were also talking
about multiFlex.

While there may not be a lot of use for multiFlex in the normal
DX chaser, perhaps except for those stations that really don't
want US responses so transmit in the US phone band but listen in
the US CW band, there are some interesting uses for DXpeditions.

AA7JV was interested in running both CW and FT8 on 160M with one
amplifier and transmit antenna. (He said setting up two stations
was too much work, and you needed to be running both modes on
those "magic nights" when 160 was open.)

He described an approach using a Flex in his talk at the Topband
dinner and in his ""The RIB: Radio In a Box for DXpeditions" session.

The idea of RIB is to put the box in the rare DX with a
generator and antenna, and operate it from the boat off shore
via UHF based internet, just visiting the DX to set up, service
the generator, and tear down.

Sorry for the delay answering, we're on holiday and the Iphoney thing is not easy with my fingers.  
Essentially, add a video capture box to the the vga output from the P3 and send that with the radio data.  Don't ask me any more, I just don't know.  The main thing is you don't need a camera to look at the P3 screen which would lose resolution and seems very clunky to me.  Looking forward to doing this in the next month or 2.  Eric gave me his card to call him when I'm ready.  He was demonstrating the system at the show via hotel WiFi which kept dropping.

Re: Visalia?

K7TV
In reply to this post by Bill Frantz
Tonight I attended a presentation by Ned Stearns AA7A on the Dxpedition version of FT8, and his extensive architectural design contributions to the Baker Island operation as well as his input to Joe Taylor's work on the protocol. While most of us don't need anything like the Baker station setup, the technical issues may nevertheless influence the direction and needs of the overall amateur gear market. With Elecraft's emphasis on supporting Dxpeditions I am sure that they look at such issues when considering new features for the K4 etc. Just a few points from the presentation that stuck in my mind:
* The radio transmit frequency must be controlled by both the logger and the JT software, which work together but are separate. I have no personal experience with FT8, but I understand that (either with the current version or very soon) the DX hunter's transmit frequency will be dictated automatically on the fly by the DX starion, within a segment of the overall FT8 frequency window, such that the DX can overlap several FT8 qso's in time. This necessitates working around the basic "single sender" RS-232 signalling scheme. Ways to do this were recently discussed here, and need not be repeated. My point: Elecraft might consider an attempt to standardize a new communication scheme for station control, such as to simplify the whole setup. Wiring a station is already disturbimgly complicated where multiple radios are involved.
* The DX station would thus go beyond "SO2R" to something more like "SO4R". The FLEX approach already seems to have an edge in savings on mulit-radio hardware; a market-leading Elecraft architecture might optimize overall hardware cost when one operator is to use 2,3 or 4 virtual radios. Just hope it can be done so modularly that a small configuration is still affordable.
* With the current interest in FT8, there seems to be pressure for the hardware to have capability to process a frequency segment that is larger than an SSB bandwidth.

Erik K7TV

Re: Visalia?

Björn Ekelund
I also enjoyed Ned's presentation.

There is however no need for new transceiver architectures to support FT8
DX mode.

The multi-transmission for FT8 Fox is created entirely through software by
combining
the baseband (audio) signal for each "transmitter" into a composite signal
fed to the
transceiver. Multi-reception is also purely a software affair.

Any modern radio, including the K3, supports this out of the box.

There is thus no need for multiple CAT interfaces.

Unless you want to run several bands simultaneously in one radio, of
course.
But that is no different from CW or any other mode.

Re: Visalia?

Re VisaIia: I was interested in the new offering from N6BT (?) 40m vertical with integral ground plane, all in one rigid package. It looks very similar to a system suggested by Moxon many years ago. I tried that using wire, bamboo sticks and a fishing rod. I don't quite see how he could take a patent on it but it was a very neat package.
