Hi,

Cost is low, complexity - if you can use Facebook you can monitor all bands

RE: [digitalradio] Re: Solving the RSID problem once and for all

[Simon HB9DRV]

I think I'm working on the 'ultimate solution' here - a SDR radio and RSID
decoder where the RSID decoder analyses between 11.025 and 88.2kHz of
bandwidth.

I already have a digital decoder built into the console, the RSID will then
alert me and with one click I'll be decoding it.

Next year I hope to have a SDR receiver which delivers 30Mhz of bandwidth so
I can monitor the entire shortwave (or just Ham bands) for RSID & other
interesting transmissions.

RE: [digitalradio] Contestia or other???

[Simon HB9DRV]

If using anything other than PSK *please* use RSID if your program supports
it. I was watching a guy calling CQ the other day and he was changing mode
so fast I had no chance to keep up.

 

I suggest PSK if conditions are OK, then Olivia.

.  Many modes work well, and most are BETTER than  PSK31, but the problem is
that there are not many hams using the others nodes,  So your lighthouse
station may be calling CQ over and over again using a mode that no one uses.
So, I would suggest  just four modes.  PSK31, PSK63 if the band is in GOOD
condition, Olivia 500/16 , and MFSK16.

 

RE: [digitalradio] I/Q Audio

[Simon HB9DRV]

Actually this is exactly what I'm doing at the moment, thus bypassing lots
of unnecessary signal path. The demodulator will come directly after the NCO
& decimator, the demodulator being fed with 48kHz of IQ data.

 

This way I can ensure that I eventually end up with near-perfect
demodulation.

Could anyone writing / contemplating any datamode software please consider

more widespread, I/Q audio inputs will allow direct use with simple

RE: [digitalradio] Re: Direct RTTY Generation

[Simon HB9DRV]

Actually at the moment I'm adding the DM780 decoder into my SDR-RADIO.com
console, the decoder is driven with the AF output for now.

When I'm ready I'll add support for driving the decoders with the data
received from the SDR radio, the only processing between the radio and the
decoder being a NCO mixer and high-quality decimator (converts the 200kHz
input bandwidth to 8kHz).

It'll be very interesting to see how the decoders will be improved with this
setup, then I will improve the decoders themselves, especially PSK and RTTY.

How will you get the shift correct? Doesn't have to be too exact but does
have to be +/- 25% or so.

I was thinking about this while walking the dog - for a simple solution a
SoftRock v6.3 would maybe a simpler / better hardware solution but you'll

[digitalradio] About digital reception and SDR.

[Simon HB9DRV]

An advantage of writing my own console is I don't have to wait in the hope
that other developers add features I would like to see.

Before the end of May I'll be decoding digital modes inside my console and
will be able to put the filter right after the mixer (and decimator). So for
a PSK31 signal I'll be able to use a 60Hz filter with *very* steep skirts
and have the optimum digital mode receiver.

I'll get Andy K3UK to test this when it's available.

After this I'll integrate DM780 so that the console can be used for TRX with
the MOBOKIT SoftRock derivative.

There's a lot more to Olivia than being multi-tone MFSK.

 

A fairer comparison with a new mode such as ROS would be MFSK as the
features of Olivia that make it so very robust could (should) be added at a
later date.

 

To put it simply Olivia hunts for the best signal it can decode and has
error correction, this 'hunting' is a reason for the greater CPU usage.

RE: [digitalradio] Calculating CPU use for multiple applications?

[Simon HB9DRV]

Andy,

As others have said, the answer's no. You list SDR-Radio.com in the list -
the CPU use depends on how you will use the software:

* Sample rate,
* Number of channels being simultaneously decoded,
* Whether you've enabled pseudo-stereo mode,
* Display size and number of monitors,
* Running PSK / CW / RTTY SuperBrowsers (similar to the CW skimmers).

It's not the number of programs, it's how you will use them.

A rough and ready explanation could be that modes which rely on phase are

you must transmit a 100% clean signal, much more important then signal
strength.

Re: [digitalradio] SDR-Radio.com Spectrum Scope

[Simon HB9DRV]

To be honest it's something you'll have to try - and at the end of Oct / early 
Nov you will be able to use it with some big SDR input files.

The foreground spectrum is a display of the last five seconds' signal, the 
background is a time-weighted display of the laast 250ms signal.

This is very similar to the IC-7800 scope with the addition of a waterfall.

Simon HB9DRV

SDR-Radio.COM software in the Developer News forum there and was wondering if 
someone here could explain to me a little of what I am looking at - besides the 
obvious.  Specifically, when I was looking at the Spectrum Scope I initially 
thought it was displaying a 2D FFT, however, the colors of the peaks change 
such that it seems more like a 3D FFT in almost a 2D format - and I don't 
understand the colors.  If this is a standard display, would someone point me 
towards a file, website or book that will explain it to me?

SDR-RADIO.com is a SDR console - connect a SDR radio such as the SoftRock 
receiver and you can receive 160m to 10m, at least 100kHz bandwidth at a 
time.

Not just a receiver - it will decode CW (similar to CW skimmer), monitor for 
RSID / CALLID, do lots of other great things (tm) which are still t.b.a. 
Once I get it available you'll see what I mean.

Being more exact - Pawel, the designer of MT63 specifically set the lower 
frequency to 500Hz. fldigi and DM780 use Pawel's code, it is not a trivial 
task to work out how to allow a different starting frequency.

As Skip says, the MT63 standard is to start at 500Hz. I think MARS have

a traditional radio such as the FT-950 or TS-480SAT.

2) Always use a UPS with 5 hours' run time on development / critical systems
3) Always make sure I have all CD's and copies of CD's needed to do a complete 
re-install.

Of the above I think RAID 1 is maybe the most important - it saved my bacon

Thinking to myself - when we use a mode such as Olivia / MT63 with extensive

Given that fldigi has the wrap feature then surely compression could be /

Re: [digitalradio] More RSID - PLEASE!

This idea was originally developed by Patrick Lindecker, F6CTE. The 
Reed-Solomon ID (RSID) is a short 16-tone MFSK transmission which identifies 
the mode in use. The RSID transmission is about 180Hz wide and lasts for 
just less than two seconds. You should enable RSID when using an 'exotic' 
mode such as Olivia so that users of programs with RSID support know what 
mode you are using.

It's supported in fldigi, MultiPSK and the DM780 v5.0 betas, as time goes on 
it will become much more common.

Just wait for HRD 6.0 with SDR console support :)

Hah,

Actually the 480 does have nice 500Hz filters so you can use this for 
getting rid of signals. The beauty of the TS-480SAT is that it's a pure 
analogue radio, the audio is good and pleasant to listen to.

Re: [digitalradio] 10m PSK

Thanks,

This morning I saw and worked SV2MKV - must have been sporadic-E.

  Yes, the 10m PSK31 frequency is 28.120.

Re: [digitalradio] possible purchase

1Hz tuning,
IF DSP not desirable for digital modes,
Rock-solid stable,
Remote-mount the radio head next to your monitor,
Excellent value for money (especially the 100watt version) - it's a Kenwood!

[digitalradio] 10m PSK

[Simon (HB9DRV)]

Hi,

Am watching 10m for any Sporadic-E PSK31 / digital - I assume the correct 
frequency is still 28.120MHz?

There's an option in DM780 to show the RF frequency + AF frequency, does 
this make sense?

In the v5.0 betas it's in Tools, Program Options, Logbook, Appearance: 
Frequency = radio + offset

Hi,

Which build of DM780? There was a bug which is now fixed.

Not everyone can see well enough to solder, not everyone has easy access to 
all the components.

When I was starting in Ham Radio I built everything, now the only reason I 
use the soldering iron is for assembling cables, sadly the eyes no longer 
have what's needed.

Look at the microHam USB Interface III - soundcard and CAT in one package, I 
have one and use it with my own TS-480SAT.

  I had a look at the Rigblaster Pro, but at US$299 I felt this was a little 
high (I could be wrong here)
