[digitalradio] New amazing JT65-HF
I was able to see JT65-HF V1.0 in action tonight. This software is so well designed that I expect it to become the "app" of choice for HF JT65 operators, especially new operators . It makes my Bozo's Guide to JT65A totally obsolete ! This software is by Joe W6CQZ , check for information about public releases (hopefully soon) at w6cqz.org Andy K3UK
[digitalradio] First WINMOR/PACLINK connection
FYI, progress is being maintained with the WINMOR project. The author (Rick Muething KN6KB ) completed some tests today where he connected and sent email using paclink and Winmor. The transmission was only across his bench from one radio to another, but it is another good sign. Look for possible WINMOR signals on HF, perhaps in a week or two. Still mainly Alpha tests, I would guess that it is a few more months before it becomes a "regular" part of the Winlink system Andy K3UK k...@winlink.org
[digitalradio] New release (4.13) of MULTIPSK
New release (4.13) of MULTIPSK
Pour les francophones: la version française de ce message se trouve sur mon
site (http://f6cte.free.fr). Il suffit de cliquer sur le lien "Principales
modifications (courriel avertissant de la sortie de la nouvelle version)".
Hello to all Ham and SWL,
The new release of MultiPSK (4.13) is on my Web site (http://f6cte.free.fr).
The main mirror site is Earl's, N8KBR: http://www.eqth.info/multipsk/index.html
(click on "United States Download Site").
Another mirror site isTerry's: http://g90swl.co.uk/multipsk/
Multispk associated to Clock are freeware programs but with functions submitted
to a licence (by user key).
The Multidem 2.2.2 fixes several bugs.
The main modifications of MULTIPSK 4.13 are the following:
1) I/Q direct interface via the sound card, for SdR transceivers
An I/Q demodulator/modulator (RX/TX) is now directly integered to Multipsk.
This one permits to receive on a 48, 96 or 192 KHz KHz bandwidth (-96 to 96
KHz) any USB or LSB transmission.
>From the SdR waterfall, the user will select the desired bandwidth which will
>be transfered to the main waterfall where possible digital transmissions in
>USB or LSB will be decoded.
The transmission will be done on the same frequency that the one selected for
reception.
To remotly control this demodulator/modulator, it is added specific TCP/IP SdR
commands ("SDR_SPECTRUM ?", "SDR_SF [Sampling Frequency in Hz]" (48000, 96000
or 192000), "SDR_FR [Frequency in Hz]", "SDR_MODE [Mode]" (Mode: "USB" or
"LSB"), "SDR_VFO [VFO]" (VFO: "A" or "B")). See "Multipsk client" version 6.
2) 200 to 3800 Hz panoramics on 36 channels
The BPSK31/BPSK63/PSKFEC31/CW/RTTY panoramics can, from now, decode from 200 to
3800 Hz instead of 200 to 2500 Hz. This function needs a powerful PC and a
screen which height is superior or equal to 768 pixels.
3) KISS mode through TCP/IP available for Packet and Pax/Pax2.
The JNOS 2.0 system (from Maiko VE4KLM) can be interfaced, in Packet, to
Multipsk working as a digital modem.
For complete details and instructions, visit the link below :
http://www.langelaar.net/projects/jnos2/multipsk
For a presentation of JNOS: http://www.nyc-arecs.org/JNOS_Primer.pdf
4) New macro to be used, for example, to regularly transmit
meteorogical data of your town. For details, see "Macros" in the index of the
help manual.
Have also been added (Clears RX window) and (Clears TX window).
5) Improvements of APRS. Among them:
* possibility to export decoded APRS Packet frames (and also PAX/PAX2 frames
for long distances APRS transmissions) to one of the many Internet APRS-IS
servers (TKS to Pete AE5PL),
* possibility to decode positions coming from the APRS-IS server and, then, to
display them on the map,
* the APRS messages acknowledgment is now managed.
Hint: on the map, the red dot is your position, bluedots are positions coming
from the APRS-IS server, black dots are decoded positions from HF or VHF.
6) Transmission of an acoustic message inside a digital QSO
It is permitted to switch from the digimode to the "Filters" DSP mode (to
transmit an acoustic message) using the combination of keys ( and
) or the key.
Note: this function must be only used in the HF frequencies where digital QSOs
and phone QSOs are both authorized.
Note about translation of Multipsk.exe and Clock .exe: the 4.12 version of
Multipsk/Clock has been completly translated to Spanish by Joachin (EA4ZB),
from French. The translation file is on my Web site (http://f6cte.free.fr).

[digitalradio] The 24-hour Feld Hell "Work all Europe" Sprint is this Saturday
With almost 2000 members the Feld Hell Club is looking forward to its second 24-hour Sprint, the goal this time to capture as many European countries as possible. DATE: March 21st TIME: Z - 2400Z MODES: All modes of Hell are allowed BANDS: All non-WARC bands are allowed EXCHANGE: RST, FH #, QTH (ONLY NEED TO GIVE GIVE COUNTRY UNLESS YOU ARE IN A U.S. TOWN WITH A EUROPEAN COUNTRY NAME.) POINTS (PLEASE READ - THEY ARE DIFFERENT THIS MONTH): 5 points for your first Hell QSO in each of the European DXCC entities. The complete list can be found at http://sites.google.com/site/feldhellclub/Home/contests 2 points for each subsequent Hell QSO with that entity. 2 points for your first QSO on each band with WW1FHC, the club callsign which will be operated by the February Sprint winner Art, WA7NB (see http://sites.google.com/site/feldhellclub/Home/contests for Art's tentative schedule of times & bands of operation) 3 points for your first QSO with a ham in a United States town, village, or city that has the same name as a European country (ex: Norway, IL). The complete list is at http://sites.google.com/site/feldhellclub/Home/contests 1 point for all other Hell QSOs (U.S., SA, Asia, etc...) Have fun, everyone! We wish you all good luck.

Re: [digitalradio] Re: New modes or old modes?
We have been very fortunate to have Tony, K2MO's detailed lab testing to figure out which modes work under different conditions and it has been surprising, and actually a bit disappointing, because most digital modes can only tolerate a small amount of ISI and Doppler. I recently thought of coming up with a list of the different modes and how much they could tolerate but the list is so short. A number of modes will work with significant SNR when conditions are pristine, but as Tony showed, once you have even 2 ms of ISI or 1 Hz of Doppler at a test point of -8 SNR, MFSK16 and Olivia 500/16 seem to be the main modes that keep working. And this includes even worse conditions with 3ms/10 Hz, and 6 ms/10 Hz. He even found 20 wpm CW to be iffy under some of the more difficult conditions. At 7 ms/30 Hz at -3dB (not -8 dB) it was CW 20 wpm and Olivia 500/16 and 500/8. This explains why you sometimes don't have good print on a number of modes, yet it seems like a reasonably good signal. Some modes, such as Domino and THOR were supposed to handle severe ISI, but they don't seem to be able to work well under Tony's tests, even under the lightest amount of ionospheric disturbance. Maybe some one can explain that? If our sunspot situation really is a Maunder Minimum wouldn't that be interesting not. 73, Rick, KV9U Christian Crayton wrote: > > > It's also difficult, in my experience, to find a lot of objective > analysis of the modes on the Internet. > > > - - - - - > > MFSK16 seems like a good all-around mode, and MFSK31 also shows promise. > I don't hear a lot of activity in these modes, but then I also have > poor, inside antennas.
