MSHV

The visual interface is QT5.6.3 All required libraries are compiled statically and are embedded in the body of the software. Additional libraries are not necessary. All settings and configurations happen immediately and do not need to be restarted, for example changing the sound settings or rig control.

New in version 2.76.6: 2026-04-28 Corrected: In modes FT4 and FT2, for AP7 decoding, signal strength indication SNR-dB. Added: In mode FT4, AP7 decoding procedure as in FT8. Added: In mode FT2, AP7 decoding procedure as in FT8. Added: Support fro all 77-bit modes of QSOs between, non-standard, compound and standard call signs, as in WSJT-X Improved latest version. Changes: Small Changes in TCI protocol. Corrected: In Interface Control RIG, Kenwood TS-990S. Added: In Interface Control RIG, Icom IC-7300MK2.

New in version 2.76.5: 2026-03-24 Added: For All FT modes widget for manual DT correction, closer to clock widget. If manual DT correction is active, will be flashing in red color, if value is zero, stop flashing (no correction). How to use, just set value from DT column for you correspondent, after the end of QSO set to zero. Changed: Tune period for all modes to 20-29 sec. Enabled: In menu decode Check-Button for average decode in mode FT2. Added: In mode FT2, support for multi threads decoding (Because period is very short 3.75s). In Menu Decode use as minimum 2-3 Threads. Added: New mode FT2, Experimental Beta version. Added: New SD FT8 Decoder (Beta version), can be found in Menu Decode and his Parameters. Note, not recommended for slow speed PS`s. Added: In the Band Menu and Band Switcher Buttons, "11 M - 27 MHz", for this reason, at first start, please correct manual Band Switcher Buttons. Added: Saving settings for Show/Hide Waterfall and TX Widgets.

New in version 2.76.4: 2025-12-27 Changed: FT8 Decoder, for better performance. Changed: The report time for PSKReporter to start time of decoded message, for FT8/4 and Q65 modes (at the request of Philip, the owner of PSKReporter). Corrected: In MSK144, Hide/Unhide "TX FIRST"/"TX SECOND" buttons. More work on Super Fox decoder (for Super Hound) (seeds tracking).

New in version 2.76.3: 2025-06-10 Added: In Network Configuration, Dx-Spot Settings, password field, for Dx clusters that require a password. Corrections: In Decode List Filters, for better recognizing call prefix with slashes e.g.(LZ2HV/B). Added: New random noise generator (different from, standard generator), in Super Fox decoder, for greater sensitivity. Added: In Auto logging information, possibility to add your own auto-login comment, if Turn Off Auto Comments and Enable Auto logging info, options.

New in version 2.76.2: 2025-04-15 Optimization: Super Fox decoder, for greater sensitivity. Added: In Super Fox decoder, sorting candidates for decoding. Corrections: In TCI protocol, if work long time application crash. Added: WSPR frequencies is restricted for TXing, in Multistream and Super Fox mode. Corrected: Application crash if using nonstandard and compound call signs, in Multistream and Super Fox mode. "Application crash during a super big pileup.", reported by Dominik from 5N9DTG DXpedition. Corrected: In Super Hound and Super Fox mode, logic for working with nonstandard and compound call signs. Added: In TCI protocol support, audio sampling rate and control for buffering audio stream on TX.

New in version 2.76.1: 2025-02-25 Added: In the version of MSHV, PATCH version e.g(v.2.76.1), for more info https://semver.org/. Added: Emitting RIG info to PSK Reporter, for more info https://pskreporter.info/cgi-bin/pskstats.pl#equipment_in_use Added: In Interface Control RIGs, Icom IC-7760, Yaesu FTX-1F, FlexRadio SmartSDR Slice A-H TCP, Guohe Q900/PMR-171/TBR-119, Ailunce HS2/HS3 and Radioddity QR20 support. Added: In Settings, Network configuration Page 2, Group box "OTP Settings". Added: OTP verification for, "Multi Answering Auto Seq Protocol DXpedition" (multistream). Start and stop TXing OTP key, is in "Multi Answer" mode, settings tab. Important, if you start TX OTP key, slots will be increased plus one. OTP key will be emitting, if you have a free slot, if slots limit is set to only one, OPT key will be emitting on the second slot. Added: Super Hound and Super Fox. Explanation: Maximum TX slots is 9, five "RR73" and four with "Reports", plus one CQ on a free slot, total = 10. If you use Free text message, maximum TX slots will be 4, plus one CQ on free slot, total = Free text + four slots + one CQ on free slot = 6. Important, Free text message is possible if you have maximum four correspondents. If you have more, Free text message menu will be disabled. How to work as Super Hound: 1. Switch MSHV to Standard or Multi Answering Auto Seq Protocol Standard. 2. On the front panel of MSHV, set check box Super Hound. How to work as Super Fox: (recommended only for DXpeditions) 1. Switch MSHV to Multi Answering Auto Seq Protocol DXpedition. 2. Go out of standard frequencies. 3. On the front panel of MSHV, set check box Super Fox. 4. Go to Network configuration Page 2, set your OTP key (16 characters) and set check box TX OTP Key Super Fox.

New in version 2.76: 2024-11-22 Added: In Macros, Activity Type "FT Challenge Contest" and Cabrillo export, for an upcoming new contest on December 7-8, 2024. More information can be found here https://www.rttycontesting.com/ft-challenge/rules/.
Corrected: MSHV randomly crashes, under Windows 11, reported by Osiel "O.C." Rodriguez NG7E. IMPORTANT: This version of MSHV is for the upcoming new contest "FT Challenge", and several small corrections. Source code of this version will not be present. Reason for this is the new functions; these new functions do not have final release in other similar softwares, (they are under development). All these functions are stopped in this version of MSHV.
