Re: [digitalradio] RFSM8000 qrg's?

Hi Wolf,

Be sure to keep us informed as to your results.

It is ironic that we can not use MIL-STD-188-110A type modulation here 
in the U.S. HF ham bands, at least not in the text RTTY/Data areas, with 
the requirement to keep the baud rate of any one tone no faster than 300 
baud. The RFSM program is about the cleanest and best design I have seen 
for a data transfer program, especially for basic use by those not that 
familiar with this technology.

With Winmor coming very soon for the Winlink 2000 system, and being an 
open protocol, there is the possibility that some of the most brilliant 
ham programmers might be willing to develop a peer to peer version. 
Perhaps even a cross platform version. It should work much deeper into 
the noise and QRN than the current RFSM software which required good 
signals due to not having the slow robust mode.

Imagine having a program that could use the Winlink 2000 system, but 
also be able to meet the larger needs as well.

RE: [digitalradio] RFSM8000 qrg's?

[John Bradley]

I have RFSM8000 installed on a machine here in Canada, although it is not
currently running. I have had some difficulty contacting Dmitri, and
wondered

if he is still actively pursuing RFSM8000. Have you heard from him ?

 

As a result we have been testing Pactor 3 for the same purpose.. it works
into the QRM/N better than RFSM8000, but is a little slower in transferring
data, at least from first tests. 

 

Cab=n set RFSM8000 up on 20M, and run it 24/7 for a few days, if you want to
try it from OE7. Let me know what frequency you want and I'll try to set it
up over the next couple of days

Hi all!

Are there CoA frequencies with RFSM8000 between individuals or
dedicated frequencies with automatic stations or servers or gates with
RFSM8000 modulation? 
We have done some good tests regionally here and would like to connect

I had one of these and it was typical for me to get 2700 hz bandpass from it. 
Did it all the time.

Are you sure the DSP is off? It sounds like the audio DSP is on and set wrong. 
Even if it's on, you can set the lower and upper cutoffs to min and max 
settings. Then you can use the IF shift to move the passband left and right 
in the IF stages. Perhaps the IF shift is not centered. There are three 
buttons to the left of the display. Hold the middle on in for more than two 
seconds. That is the IF shift. To start off, it needs to be centered. Move 
the selector knob (lower left) to get a large dot on the right hand of the 
freq display. If you are away from the IF center, you will get an up or a 
down arrow instead of a large dot.  Once you get a large dot, hold it in 
another two seconds to set it.

Then select the two submenu items for DSP lower limit and set it to as low as 
it will go. Do the same for the DSP upper limit and set it to as high as it 
will go.

You should get about 3 khz bandwidth.

Re: [digitalradio] RFSM8000 and Yaesu FT857

[kh6ty]

Les,

According to the RFSM web page, you need at *least* 300 to 3000 Hz audio 
response, and preferably 300 to 3400 Hz. Even an INRAD filter is not going to 
completely meet the 3000 Hz high end requirement, much less a 3400 Hz 
requirement. I think some other Yaesu rigs optionally support a 3300 Hz  high 
end with an optional Yaesu filter, but my point was that if your low end is 
only 700 Hz, something is misaligned on your FT-857 to start with. You also 
could wind up paying for an INRAD filter and still find the low end or high end 
inadequate because the audio itself is rolled off too fast.

Anyway, it is probably better to use something other than the FT-857 for 
digital modes as finding the ALC threshold is very critical for getting low 
IMD, even on PSK31, and drift is a problem on 2 meters unless you have the TCXO 
option, which my FT-857 does not.

  Are you sure it is the IF passband? If your BFO injection frequency is set 
correctly, you should be able to pass 300 to maybe 2200 Hz. Otherwise, SSB 
phone will have no lows.

  If you have audio transformers in a homebrew interface, make sure they have

Hello,

You should be using the digi port, and there is a specific setting that 
allows you to center the filter passband around typical digi signals. I 
find 200 hz up works best for ALE.

Since the signal is now centered, I can then even use the DSP bandpass 
to really tighten up.

If you have not centered the signal, or are using USB you will need to 
turn DSP bandpass off.

I don't know how the signalink interfaces, but the 857/897 needs no 
interface for soundcard/tnc usage and is already decoupled at the 
digi-port on the back of the radio.

Have fun,

Re: [digitalradio] RFSM8000

[Rick]

Normally, when I am operating digital modes, I start out with the full 
3.6 kHz bandwidth and only tighten it up when I need to. The "non 
standard" mode is likely a much better fit for some rigs. In fact, it 
would seem that some rigs, even some newer ones, would not be able to 
operate some of the wide digital modes when you read the passband 
information.

When I look at the specifications of new rigs, I now take that into 
consideration. ARRL publishes very detailed information on the exact 
passband for the rigs they test although there is likely some variation 
with individual equipment.

Hi John,

Using RFSM 2400, I was able to connect with the non standard mode, but
had to go to 50 watts, and initially showed a 5 dB S/N connection, but
nothing would go through. There is a beep tone at the beginning of each
transmission and I see a large spike on the spectrum display which I am
guessing should be centered on the red vertical line? It is difficult to
have enough time to estimate where the spike should be set but your rig
is apparently very close to the exact frequency.

I still very much appreciate the constellation display and this program
has been the first that that has allowed me to see this dynamically
displayed on screen. I have seen this on diagrams, of course, but seeing
it in a real life display it is very impressive

Below the constellation display you will see a +/- figure on 
receive -
just make this figure read 0 (zero) or as close as you can using 
your main tuning

Re: [digitalradio] RFSM8000 Mail Server

[Leskep]

Hi Howard

The RFSM mail server can send email - originated by any outstation
which can connect to the Mail Server by radio - onto any internet mail address 

Any mail coming from an internet mail address and addressed to the
servers email address in the "To" line and then addressed to the
callsign  (in the Subject line) of any remote which can connect to the server - 
will be placed
in its  Mailbox on the server for collection by that station as required
[Delivery to multiple (callsigns) or email addresses is handled bothways

Attachments can be included

Just the action of connecting  to the Server by a remote station will create a 
mailbox 
in the name of the connecting station on the server

When a remote station sends an email to the server a folder called OUT_EML is
created as a subfolder of that callsign and the outgoing mail is picked up from 
there
at the time determined in the server Setup - every X minutes 

See "using e-mail.txt in the README folder in RFSM8000

Hope that explains it enough for you

Mail Server facilities)  for the month of January
Normally you would only get the Mail Client software for this price

Yes it is backward compatible with the RFSM2400  program for file transfer and 
local email server services

Yes - RFSM2400  Ver .498 is available as Freeware for amateur use   from
 http://rfsm2400.radioscanner.ru/

What I can say is that the software works very well as a mail server for e-mail 
from Remote stations to internet addresses
and also from Internet addresses to Remote Stations and works very well for 
file transfer at high speed up to 
6670 bits per second - this is not often achieved on HF but speeds of 4000 and 
sometimes 5333 bits per second
can be achieved under good conditions on 20m band and speeds up to 2666 bits 
per second on 80m and 40m
bands is quite common and sometimes even higher - depending on conditions

On tests that we are doing here it is quite comparable with P3 for transfer 
speed (under the same conditions)
It will not work as far into the noise as P3 but it will hold a link and still 
transfer data in quite noisy situations
Two of the stations testing here have P3 modems and I quote figures supplied by 
them on tests they
have done on both P3 and RFSM8000

Yes in the setup you can configure most radios for use with CAT control for PTT 
keying (providing you know the required
strings to enter into the fields  - also serial port PTT - and Vox is available

BTW I have no financial interest in the Software or the Company other than that 
I have been doing on air testing
for the RFSM-IDE Group along with a group of other VK  amateurs - and enjoyed 
the testing also

Hi John,

Can you tell us anything about how this technology is working out? From 
what I can see from the web site, it replaces and is backward compatible 
to RFSM2400.

Although we can not use it here in the U.S. on the frequency you 
selected, it could be used to send images in the phone/image portions of 
the U.S. sub bands. What is your feel for the robustness or lack of it, 
etc.? The waveforms appear to be based upon the MIL STD modes although 
some may be modified.

Have you registered the program? Or plan to if the 30 day test has not 
run out?

The cost seems very high to me at $290 USD for the pro version, but even 
the $180 USD price for the "ham" version is still impractical for many 
to purchase unless they could actually use it, and it would work as well 
as say, Pactor 3 or close to it.

Is the "old" RFSM2400 program available for free ham use? I now have the 
capability to key a COM port PTT mode so could use the older program. I 
see that the new program claims to support CI-V.

Any thoughts on this? Anyone else who has experience with either of 
these programs?

Re: [digitalradio] RFSM8000

Hi,

You can set the data rate and you can use 300 bps if you wish. Also, its not 
actually 2400 baud but rather 2400 bps. If I remember this right then a user 
data rate of 1200 bps would require a channel rate of 2400 bps. That channel 
rate is then sent at 1200 bauds using 4-psk (two bits per state change).
But yes, if I remember the standard right then the actual baud rate is always 
more than 1200 bauds. 75 bps is a special case using a channel rate of 150 bps 
but it uses a really long word for each bit and the resulting baud rate is 
still too high (but legal here in europe).

John,



If this modulation is the MIL-STD/FED- STD/STANAG 8PSK waveforms, 

wouldn't they be at 2400 baud at all times? We can not use baud rates 

over 300 here in the U.S. on the text digital portions of the bands, but 

they could possibly be used in the voice/image portions for sending 

images/fax.



Possibly packets could be received as long as you are not linked and the 

program can send unconnected packets?



What will be extremely helpful is for any experiences you have with data 

throughput vs S/N and interference.



It is still curious to me that the promoters of "ALE" modes do not test 

these protocols in the voice portions of the bands. Also on 6 meters and 

up. There has been absolutely no measurements of S/N in real world tests 

on the amateur frequencies that we have heard thus far.

Hi All
I will be sending a beacon transmission every 10 mins
for the next two hours (till 0415 utc) using non
standard modulation on 14109.5 khz - with beam at USA/VE
Hope someone may hear it - maybe a bit too hopeful hi

RE: [digitalradio] RFSM8000

[John Bradley]

Tnx fer the note, Howard

 

Over the next week or so ,we should have VE5GPM up and running 24/7 on RFSM
8000, not beaconing, but ready to receive calls and transfer files.

 

VE5TLW and I will be working on learning the software and making a little
noise with same. I think we will find an alternate frequency to play on
since

14109.5 is busy with ALE soundings ,and will let you know what it is.

 

To that end would welcome input from the US ham community since this is a
more critical issue south of the border than here.

 

I THINK that you are able to use the non-standard modulation which is 2.4khz
wide , as opposed to the Mil Std 188 which is 3khz wide.  You should be able
to copy any packets in the Packet window.  

 

Again , get some opinions from others in the US as to whether this is legal
, and where in the US band plan it could be used.  At first blush , it
certainly has some promise.

Hi Howard

RFSM8000 is backward compatable with RFSM2400 and
providing you have the modulation set correctly to
non-standard .3 to 2.7 khz you should decode the
Beacon packets - check to see if the signal has a
TX carrier freq of 1500 hz for non standard mode

Or maybe the transmitting station is in Mil Standard which
has a TX carrier freq of 1800hz

Re: [digitalradio] RFSM8000

[Rick]

Les,

What do you see as the advantages of RFSM2400 over the 8PSK2400 baud 
STANAG modems that we have been talking about recently (along with 
RFMS2400)?

The only comment that I have heard so far is that it requires a good 
signal to work. Athough hams can not use these modes here in the U.S. on 
the text data portions of the bands, they can use them on the 
voice/image portions if they are sending images or fax. Curiously, I 
have heard no experiences with SSTV or other image operators using these 
modes.

73,

Rick, KV9U
