Re: QRP success with Opera 2

Looking back - 8 years   Was it really that  long ago  !

O db , thats  round +25 db over the op2 limit 
15 mW  carrier power would of decoded 

Be interesting to  make the  comparison to day ?

AprsGate 0.98 was published:


http://www.dxsoft.com/aprsgate.zip



AprsGate versions history

V0.98
Baud rate of 23.44 Bd was added. The signal bandwidth in this mode
is about 500 Hz.
The center frequency of the audio signal at this speed is about
1711 Hz and cannot be changed by the user.
English help-file was made.

V0.97
Baud rate of 46.88 Bd was added. The signal bandwidth in this mode is about one
kilohertz.
The center frequency of the audio signal at this speed is about
1711 Hz and cannot be changed by the user.
To reduce the load on the processor, you can reduce the number of simultanious
decoding baud rates (Settings / RX Speeds).
The Error Rate of messages containing uncorrectable errors is calculated more accurately now.
This version will work till 31 January 2021.

FST4 on 40M , a success !

Andrew O'Brien
 

Just "because it is there" , Phil W1ZOT and I tested FST4 on 40M tonight and it performed well . 1200 mile path  New York to Texas path. . W1ZOT using 5 watts and me using 3-4 watts with battery pack in the IC-705.  A little tough at 30 seconds but easy at 60 seconds, decoding down to -24 SNR .  Both using homemade antennae (sloper and vertical).   Some of you may recall that this group (when on Yahoo) started the JT65A utilization on HF way back when.  In that same spirit of adventure, Phil and I thought we would give FST4 a whirl.  We have not tried the 120 second variant yet   Joe Taylor intends this mode for LF MW work but it could be useful for HF.

Re: "RTTY and Data" band plans ?

Hey Andy!
                Below are the ARRL and IARU Region 2 Band plans for the 20 Meter Band. Source of info is on the images below. I just got the one from the ARRL website, but have had the IARU band plan dated October 16, 2016 in a PDF file I downloaded and saved on May 5, 2019. It shows RTTY starting at 14.070 and the IARU region 2 band plan shows DM (Digital Modes) starting at 14.070 also.The bottom image shows both the currency and proposed ARRL band plans with the latter not having been accepted by the FCC yet. The proposed band plan shows 14.105 to 14.150 for RTTY, Narrow and Wide bandwidth data and all ACDS stations.

Re: "RTTY and Data" band plans ?

Thanks Tom and Ralph.  Yes, I agree I would need to make sure I am not out of band with my signal.  I don't intend to drop that far down.  However, it has occurred to me that I might sneak below 14065 to operate some digital modes including FT8  IF I had a 'sked" with someone, just to get away from the maddening crowd.  Just for a few minutes. Never on a weekend unless on a WARC band.

Re: "RTTY and Data" band plans ?

Ralph Mowery
 

As long as the signal and sidebands are still above 14.000 you can legally  operate there.  14.003 may be pushing it, but around 14.005 to 14.010 should be ok .  Again you have to be careful and not talk about the dial frequency , but what is actually coming out of the transmitter.

Lets say your dial is at 14.003.  Using some modes and tones and side band selection, you could push the signal below 14.000, but using the other sideband  would be fine as the signal would start at 14.003 and shift higher.

I would not really want to operate anything but CW that low to keep the  CW operators happy.

K3SIW USA LOW-FER BAND #opera#LOWfer

K3SIW USA LOW-FER BAND

Chance to to go ' fishing ' for some real qrp-dx , lowfer band is limited to 1 watt DC input to PA and short Ae system ....K3SIW is sending , using Op32 mode , to detect/decode . use the windows opera app , set to 136 KHz , use these setting's ,
qrg = 185185 carrier
Set Opera to 136 ,
set control to vox or com port
set rx to ..183685 USB
Dial set for correct opera frequency
185185 - 1500 = 183685 USB
set beacon = off
Watch , wait and see , opera will report as 136 band

Re: Dstar on 14340: Weird.

 

This particular net is a propagation test. As the bands improve other, traditional nets should emerge.

Sorry, English help is not made yet.

You are welcome to use Google translate and ask me about details :-)

Shortly, AprsGate forwards HF Pager "beacons" with coordinates to APRS-IS server as "Position" or "Object" packets.

"Position" packet is sent if a beacon text starts with tag like

#;N0CALL-12;


Beacons without coordinates and general messages which have such tag, are forwarded as "Status" packets.
