Getting Started?

"mdgolfbum" <jim@...>
 

Is there a "getting started" page somewhere? I've never found much
interest in digital modes so I'm coming from a CW background.

Should I first get a PSK31 install going then try this out?

Is there a recommended interface between rig and sound card?

tnx

RX-TX Offset

"Bill" <wa0ypl@...>
 

I'm new to PSK. What offset do I put into my 817/857 for use on PSK31?
The manual recommends +2100. Right now it's set to 0. I'm confused
about offsets.

Re: 2m default frequency...

Hi Skip,

I'm using a Kenwood TM-D700A, and it is an FM only. I have a TS-480, but only goes up to 6m. Working great on FM.

Thanks and 73!

Hi Jeff,

NBEMS is primarily intended to be used on VHF SSB with PSK audio.

The default of 144.144 is what appears to be the nationally agreed upon
calling frequency for PSK31, and easy for people to remember, so that is why
we chose that frequency as a default. Changing the default was excactly the
right thing for you to do.

Noticed in VBdigi that the 2m default frequency is 144.144 with the
tone at 144.145.

Not sure about your radios, but I can't tune to 144.144 because my 2m
radio only allows 5kHz steps... closest I can get it 144.145.

I deleted the default and put in my own. Perhaps change the default?

Has there been any comparison study between NBEMS and "Air Mail" via 2 Meter Packet?

I know Packet requires a lot more band width than PSK31, but that wouldn't seem to be a problem as there is hardly any Packet activity now. There also might be an equipment advantage to Packet with all the old FM rigs and TNC's gathering dust.

Also, what frequencies are being used by NBEMS at the present?

73, Jerry - W6LQR

Jerry,

The idea behind NBEMS is to be able to reliably bridge a disaster area for up to 100 miles, without dependence upon a repeater system, which may be inoperative.

By using PSK63, NBEMS is able to do that on 2m with small, portable, antennas, or on HF, using NVIS antennas.

The range using packet is considerably less than 100 miles, as without any repeaters in a high location, I believe that the typical reliable range on FM simplex is usually considered to be only around 30 miles, depending on the terrain. In a system like FM, once you have achieved full limiting, ARQ is probably not needed anyway to insure error-free message transfer.

The initial frequencies for 2m NBEMS operations have been chosen to coinside with the nationally agreed upon PSK31 calling frequency, which is 144.144 MHz, USB, and extending 2.5 KHz higher. When NBEMS becomes widely used, it is recommended that PSK63 activity might have to be moved starting 2.5 KHz higher than PSK31 activity, as is the convention on the HF bands. This would be done to prevent PSK63 signals, which are twice as wide as PSK31 signals, from interferring with adjacent signals using PSK31.

Due to the "resuable" nature of 2m frequencies (i.e. they do not travel long distances very well), it will probably be a very long time before PSK63 activity on 144.144 MHz becomes a problem to PSK31 operators, if ever. Here in South Carolina, we run a twice-weekly PSK63 net on 144.144 MHz, USB, around 1500 Hz tone frequency, and there is never anyone else in the bandpass, but we wish there were more activity!

73, Skip KH6TY

Not in the main window , but there is a choice in the setup area to do so. But it requires some extra keystrokes to invoke and return to the default. Plus I have found that a station that is inverted quickly learns to get right-side-up when no one is answering their calls.

USB RTTY is the default in NBEMSham and works perfectly, with no problems decoding. I know this is not the "norm" for RTTY, but it works and works well.

You would have to use the LSB check box on the Waterfall configure dialog. You should use your transceiver in USB for all RTTY on all of the bands for normal right side up reception and transmission of RTTY.

If you mean some actual on-air work, why not just ask here and maybe set up a sked to try it out. I'm sure there are many others that might want to do the same.

I'm available if you want to give it a try. Any band 10-160. Of course I may know even less than you, but I'm willing to try.

We have tried to make the software operation intuitive and not need any manual, but there is Help in VBdigi and on the NBEMS web page at http://www.w1hkj.com/NBEMS. Look for the .pdf help files.

Re: 2m default frequency...

Hi Larry,

My radio is a D700, FM only... not a biggie. Way up here in the sticks there isn't any SSB traffic in the lower end of the 2m band. I'll check out a location in 146.xx for us FMers. Thanks!

On January 27, the 25th running of the John Beargrease Sled Dog Marathon will start (http://www.beargrease.com/). Being President of the club (BARC, http://www.beargreasearc.com/ ) that provides communications for the race, I would love to have digital file transfer communications at net control, road crossings and checkpoints. I have asked our race volunteers to equip themselves with the NBEMS and we will test it out along the course using 2m, 80 and 40. It remains to be seen how many will show up with the right equipment. I'll follow up with a report after the race.

73!

My FT897d only does 5 kHz steps in the FM mode, the reference to 144.144 is for SSB mode. The lower part of 2M is usually reserved for CW/SSB modes. Try your rig using USB (or DIG) mode - BTW using a simplex freq @... in FM mode, works great and brings in a lot more Hams that don't have SSB capability.
Perhaps in the future we can try some "0 region" 80/40 M VBdigi? It might prove interesting to check out.

Re: Setting up Sylpheed account

Hi Skip -

I am actually using gmail and PSKmail...

My problem with PSKmail is getting communications between PSKmail and
Sylpheed set up - I assume that the same sort of setup takes place for
NBEMS.

I can see the e-mails coming thru PSKmail, but they never seem to make it
to Sylpheed - I assume because some file pointer or path is not set correctly
somewhere...
