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.

HF Pager versions history

2.87
The "Carrier detector" was radically redesigned.
A symbol sync was slightly improved
Bugs in the Error Rate calculation were fixed.
2.86t
The test version - carrier detector is disabled.
2.85
The signal quality indicator (Error Rate) is been writing into the text
of the received message.
Baud rate of 46.88 Bd was added. The signal bandwidth in this mode is about one
kilohertz, so use it in those parts of the bands in which wide band digital modes
are allowed. 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).
2.80
CPU load has been drastically reduced.
Channel busy detection algorithm was improved.
Channel sharing algorithm was improved.

Error Rate (a number of corrected errors in percent) is included at the beginning of object

Beacons from stations with "trial" IDs (above 64999) are transmitted as objects HFPDxxxxx
with fixed comment text.

Are JT-Alerts and GridTracker nothing but distractions ?

Andrew OBrien
 

I’m beginning to slide in to a “back to the basics” mood . I have had fun over the years tackling all kinds of software applications that are add-ons to the basic logging and rig control software . However I have lately got rather tired of tweaking a plethora of virtual serial ports and coping with the impact of Windows updates on perfected settings . One thing I notice a lot on various email groups and social media pages is the endless posts about Jtalerts and GridTracker . Both extremely useful tools, but is it worth the hassle ? So many posts about features not working , Windows screwing things up, and the like . I want less time troubleshooting and more time on the air . My basic Commander , DX Keeper, and Multipsk combo is easy and fairly bulletproof when it comes to the influences of other software and Windows . Likewise, I backing away from multiple receivers and “slices” of bandwidth running simultaneous decodes of several different digital modes . Time for just one band and one mode at a time . I even sold my Icom 7610!

Re: N-SSTV

Donald Evilsizor
 

Pat,

I never operated SSTV myself, but copied quite a few on 20M as a intercept operator for the military
in Germany back in the mid 1970's. Had all sorts of equipment at my area.

Used what we called a transverse oscilloscope with P-phosphorous display and could see the
visual display fill in, plus it had a paper print display of the pictures. Additionally could record
the signal on a 7 track recorder to play back later.

Started copying ham operators in 1960's at another location in Germany on CW when work
was a bit slow. And back at our barracks the guys had a ham station, so used to sit in
and watch them work all over on a 15 watt home-brew XMTR with a NC-98 RCVR.

Sad never got my ticket until 1983 after retirement from the army.

This is an interesting problem. Wires-X setup instructs to turn “listen” to on. And it causes echo.

WIN 10 Realteck mixer 'echo' / feed back #win10

Cause and cure of a strange  echo / delay on the  audio ,  varied  by the  mixer volume  slider ..

WIN 10 Realteck mixer 'echo'

Little odd , while routing audio to data apps on win-10 pc , the sound mixer
provides a simple 'connect' point , for the app to connect to the audio stream

However , for some reason ,setting or option , as the level is increased , its accompanied
with an unexpected echo ,howl round, ''feed back'' ,

As far as I can tell , all the 'special effects' are set to off , one playback device selected
audio is available via the ''mixer'' normal apart from the echo .

Q what could be causing the ring-round , something must be linked back to the
input , but -what and where ? any ideas ? , had the same ?

Tnx -Graham

Have a look at the Properties for the Recording Device....you may need to run mmsys.cpl to get to this detail - (a desktop shortcut to mmsys.cpl is useful)

The Recording Properties for the device in use will show a "Listen" tab, if "Listen to this device" is ticked that might cause your unwanted "echo" effect

REASONS WHY THE YAESU FT-60R IS MY EDC PORTABLE RADIO

Dora Tamilta <doratamilta@...>
 

It’s been more than a decade since Yaesu launched the FT-60R dual-band handheld radio. It has since been superseded by newer entry-level models like the Yaesu FT-65R and the latest FT-70DR C4FM-capable radio. But the FT-60R still holds its own against these newer radios. In fact, even if I have the venerable Yaesu FT-2DR, I still carry the FT-60R as my EDC (everyday carry) radio.
 
Here are reasons why:

Obviously, you can’t pick your parents, otherwise Ozzie and Harriet would have had thousands of children. However, who your parents are can have a huge impact on how long you live. Diseases that can cut your life short, like heart disease, Alzheimer’s, and most types of cancers, have a strong genetic connection.

More exactly (radio_freq + audio_center_freq) should be the same (if USB is used).


For example, carrier at 3570 kHz and 1700 Hz audio is the same as 3570.1 kHz and 1600 Hz


Decoder is robust with frequency error about 100 Hz (see wider marks at waterfall).
