Opera digital mode. The new software by EA5HVK, Jose Ros for QRSS on Weak signals

Opera is still in Beta test, the latest version is V.1.8.8 (Download from Link below!!) – The new “Opera” Single carrier Data/Beacon mode Tx/Rx, is created by EA5HVK, Jose Alberto Nieto Ros, by request of GØNBD for Ham Radio CW Community – This software, complete windows compatible Tx/Rx package with internet spotting and chat facility, COM-port keying and audio tx drive, is free!

Opera QRSS. Il nuovo software sviluppato da EA5HVK, Jose Ros su idea iniziale di GØNBD, si utiilizza per comunicazioni CW standard QRSS per segnali deboli, anche immersi nel rumore e con potenze QRP. – Opera è simile al già noto WSPR/JT45, ma con propri algoritmi in ambiente DSP e codifica tipo OOK (On Off Keying), con selezione di tempi di intervallo da 1 a 60′ e in più altre novità in evoluzione. – Infatti è ancora in Versione Beta, V.1.8.8 – [Nota] Anche gli spots di Opera si possono seguire in tempo reale sui sistemi automatici: PSKreporter e Hamspots.com (vedere Link)

 The new software “Opera”  Beta, developed by EA5HVK, Jose Ros (author of the now established ROS Data mode!) using DSP techniques, it’s a alternative QRSS for weak signal experiments on 136 & 500 kHz and for HF all bands (80 to 10 mt) for Ver. 1.1.2 up – Better than standard QRSS, similar like WSPR, but with Opera you can choose your own interval time between 1 and 60 minutes.
CAT Link embodied and Tx by COM port Key or Audio drive Tx\Rx COM port switch faclity – Decoder are possible with S/N – 26 to -38 dB (Rx speed auto-selected!) The spots are visible in near realtime to interested parties with PSKreporter and Hamspots.com (see the links) – This as a way of providing data operations for stations that only had the CW capability. The most up to date information on this mode can be found at groups.yahoo.com (see the link up)

YAESU: early 2012 release a Digital C4FM (4-level FSK) Handheld – The New Brand logos

YAESU Amateur Radio Division of Vertex Standard, has relesed 27 December, 2011 an extensive Publication in PDF:  ”A Digital Communications Guide for Amateur Radio Operators” (on its website) – The publication confirm that Yaesu positions itself for digital radio battle against Icom D-STAR business !!

Big news still: YAESU writes “early 2012, we will release a C4FM (4-level FSK) FDMA Handy-Talky and Mobile Transceiver into the Amateur radio market” !

News update: The new Brand Logos already appear on website of the ©Yaesu USA Inc. (earlier name: Vertex Standard US Headquarters)

[Note]: the recent corporate reorganization, that brings Vertex Standard’s LMR (land mobile radio) division to Motorola, and breaks Yaesu off into a independent corporation again, known as YAESU MUSEN  Co., Ltd,  for Amateur, Marine and Air-band business divisions. – The US subsidiary wil be YAESU USA Inc.  [please wait for the any official information !]

Yaesu Digital radio system that uses C4FM (4-level FSK), and is very popular in professional commercial markets, is known ad DMR (Digital Mobile Radio) [note: no DRM…!) is used primarily in the European and Asian markets, and is also known as dPRM.

Currently GSMK modulation is still being used by D-STAR in 2004, was introduced to the Ham bands. – ICOM D-STAR was the first in the game to promote digital voice and data specifically for amateur radio, and they have quite the stronghold right now – It will be interesting to see ICOM’s reaction to YAESU’s entry to the digital radio market that appears to be early 2012, we will release a C4FM FDMA Handy-Talk- (!! please see the image up! click its to enlarge).
