Hi Mike:

My name is Tom and my call is N8TL. I wanted to pass along to you some information that you might not be aware of.  The previous owner of the W8DN call sign was Russell Flora from Sylvania, Ohio.  Located on outskirts of Toledo.  In my  teen days, I would attend Mobile Radio Club meetings at Russ's garage. Russ was a good friend and Ham Radio Mentor. His primary mode was AM on 160 meters. There were a lot of 160 meter mobile hams in those days.  This time frame was the late 1950's to the mid to late 1960's.  Thought you might be interested in the history.

Regards, and, 73,  Tom N8TL

I used the band once or twice, for a MARS exercise, on phone. I don't think FT8 is really compatible with the very unclear regulations on that band. Don't look me up there. There is plenty of room elsewhere.

There is no ARRL award for operation on that band. So there is less incentive to operate there anyway.

You have to add a connection between your rig’s CAT control and the computer. The SignaLink  provides audio and PTT connections only. It does not include any interface for rig control (frequency, mode, etc).

The SignaLink does not have any connection for radio control. It is only a sound card for audio plus a PTT signal derived from the audio.

You need a separate connection for radio control. In the case of the FT897, that would be from a serial port or USB-to-serial adapter from the computer, connected to the radio's CAT/linear connector through a CT-62 or equivalent adapter.

I’m not aware of any complaints by the NTIA against radio amateurs for using FT8 on 60m.

The volunteer monitor program nor the FCC are sending out violation notices. I keep abreast of enforcement issues and I’ve asked numerous departments at ARRL. This isn’t a concern with anyone there.

ARRL doesn’t have any awards for 60m contacts. So anyone doing 60m contacts there does it for their own enjoyment.

Hi all,

IMHO, I think Seannon is on the right track. 

I personally have never keyed a mic on 60m yet because I have not found a need. 

But I think the root thought that MAY have been behind the 60m allocation may have either never been printed or said, but was the reason. Who knows...

That is to give Amateur Radio operators a common set of frequency channels with government groups to communicate back and forth, directly during an emergency without operating split mode. 

Copied from Seannon below
 The NTIA expressed concern about possible interference and requested that amateurs limit digital operating to PSK31 and PACTOR III only.”

It makes sense that it has been mentioned specifically that voice and limited PSK31 and PACTOR III be used, because those would be the modes that would be used during an emergency situation. These would also allow the primary users to interrupt secondary users conversations for primary use of their channels. 

I would suspect that the channels are hard programmed into their radios that probably do not have a VFO to allow them to move to an off center conversation. 

Please consider these thought going forward. Remember these are government channels and we are allowed to share use, probably to allow us to get our stations ready to be used during an emergency. 

I don’t like to write long emails, but I felt that more logical thinking might help this conversation some. 

I apologize in advance if I wrinkle any hairs with this line of thought. 

Best Regards to All,

Butch N5SMQ

Bonnie, with the current rules for the united states hams, I really don't think we should be doing FT8 "Business as usual" on the 60 meter band at all! the rules state that it is 1. CHANNELIZED, with voice allowed on USB 1500hz down from the channel's center frequency, and data ONLY CENTERED ON THE CENTER FREQUENCY. 2. ONLY ONE STATION CAN TRANSMIT AT A TIME 3. WE ARE NOT PRIMARY USERS ON THIS BAND.

So, while ALE, SELCAL, and modes like OLIVIA are digital and conversational, FT8 is more transactional, I.E. call, signal report, location and move on to the next contact... and depends on the varying of the AF within the passband, this is NOT allowed per the current rules, it's the center frequency or nothing, not the center frequency shifted 500 hz, 746 hz etc, and the way FT8 utilizes multiple AF to allow transmitting of multiple stations at the same time without "walking on the other stations" this is incompatible with the rules stating only one station may transmit at a time

to make this a bit more visual, check the 60 meter section of the band chart, it pretty much says that FT8 and FT4 aren't compatible with those rules without mentioning them.

we really need to take care of the bands we have, they are hard to get and can easily be taken away, this is one where we are a secondary user, which is even more important that we use our strengths and common sense

Digital Operation
Our expanded privileges on 60 meters were the result of collaboration between the FCC and the NTIA – the National Telecommunications and Information Administration, the agency that manages and coordinates telecommunications activities among US government departments, the primary users of the band. The NTIA expressed concern about possible interference and requested that amateurs limit digital operating to PSK31 and PACTOR III only.

It is certainly possible to interpret the FCC Report and Order somewhat broadly as it concerns digital operating on the band, but be careful not to read too much into the text.Therefore, as a practical matter it appears that any J2D data emission is to be permitted up to a bandwidth of 2.8 kHz, provided that care is exercised to limit the length of transmissions

With an eye to the potential for expanded 60 meter privileges in the future, the ARRL believes it is critical to cooperate fully with the NTIA. Therefore, the ARRL asks all amateurs to restrict 60-meter digital operations to PSK31 or PACTOR III.

With PSK31 you must operate on the following channel center frequencies:
Channel 1: 5332.0 kHz
Channel 2: 5348.0 kHz
Channel 3: 5358.5 kHz
Channel 4: 5373.0 kHz
Channel 5: 5405.0 kHz

The easiest way to achieve this is to place your transceiver in the USB mode and tune to one of the suppressed carrier channel frequencies shown in Table 1.

With your PSK31 software display configured to indicate audio frequencies, click your mouse cursor at the 1500 Hz mark (see below). With your radio in the USB mode, this marker indicates the center of the channel and it is the frequency on which you should be transmitting.

PACTOR III operation on 60 meters is straightforward. With your transceiver in the USB mode, tune to one of the suppressed carrier channel frequencies shown in Table 1. Note that only live keyboard-to-keyboard operation of PACTOR III is allowed. Unattended automatic operation is not permitted.

I buy as close to the present leading edge of computer tech that I can afford at

had five to eight maybe even ten years of use out of it. Four years ago I bought
an AMD 9590 CPU based computer, it does all I ask and more, but I don't ask it
to do much other than the usual assortment of ham radio software, play music or
video and I like to play World of Warships as well, does all I ask of it without
any grief except for having to clean out the dust twice a year.

As long as your computer can handle the load that you impose upon it, it is
fine. The only major reason that I can think of to replace the computer is
because the OS is out dated thus the new versions of software will not run on
the present machine.

Win 10 I would guess is getting closer to the obsolete point, I wonder if MS
plans to have their new OS as a subscription and one pays a monthly fee to have
use of it, if so, I can see a huge move to Linux.

Hi.
I wonder what I am doing wrong because I cannot clone configuration when using wsjtx version 2.1.2 and KDE
similarily when using wsjtx version 2.1.0 and Ubuntu 18.0.4.
I made the first configuration by setting general, rig data and mode FT8 on 40m. Then I tested it and it was OK.
I cloned it and  switched to it and it was OK. I changed mode to FT4 on 40m and it was OK., renamed the first and switched and it is OK.

Now I am  trying to do the same  using wsjtx version 2.1.2 and KDE.
I did as before but both clone and copy saved nothing.
I tried to delete extra configurations but they pop up every time when restarting the progam.
What is wrong or what am I doing wrong?

The last active configuration is OK when restarting the program.

I have to confess to being more than somewhat bemused by all the kerfuffle that seems to be afflicting USA amateurs' use of FT8 on 60m, but it does appear that you're having to comply with some extremely restrictive (and in some cases seemingly unenforceable) rules that fortunately don't seem to have made their way across the Atlantic (yet).

I was operating on 60m late last night, in USB mode and with a dial frequency of 5357.0kHz, and at one point saw half a dozen or so signals from USA stations spread widely across my 2.5kHz-wide waterfall that's centred on 1500Hz so most if not all of them were non-compliant with the centre-of-channel rule.  I hope nothing nasty happens to them...
