Author Topic: WinWarbler update  (Read 1926 times)

WinWarbler is a free Windows application that supports multi-channel PSK31 and PSK63 via PC soundcard, as well as RTTY via soundcard and/or an external modem (e.g. KAM, PK-232). Soundcard PSK is accomplished using Moe AE4JY’s PSKCORE engine, and soundcard RTTY is accomplished using Mako JE3HHT’s MMTTY engine.

WinWarbler is a member of the DXLab Suite; it can be run independently, but when other DXLab applications are running, WinWarbler will automatically interoperate with them:

- Commander: provides transceiver control for most Elecraft, FlexRadio, Icom, Kenwood, TenTec, and Yaesu transceivers

- DXKeeper: provides full-function logging, progress reporting, duplicate-checking, and QSL management (independently tracks each QSO’s confirmation by paper,, and LotW)

- DXView: displays a live world map bearing station locations, the solar terminator, and beam heading (controls most PC-connected rotators)

- SpotCollector: captures, announces, and analyzes DX and WWV spots from up to 4 telnet clusters, the DX Summit web cluster, and a local packet cluster

- PropView: generates graphical propagation forecasts (using the included IONCAP engine) and monitors IARU/NCDXF HF propagation beacons

- Pathfinder: provides instant access to more than 100 web-accessible sources of QSL route information

- Launcher: initiates or terminates a specified set of DXLab applications with a single click

WinWarbler is under continuous development; during the last year, there were 81 releases bearing 119 enhancements, many suggested by the user community. Given this rate of evolution, I do not post “new release available” messages on reflectors other than DXLab. Its been awhile since the last announcement here, so I thought I’d summarize the major improvements:

1. up to 32 general purpose macros can be defined, plus a macro that is executed on entry to PSK and a macro that is executed on entry to RTTY

2. many new macro operators have been defined, including a “Last QSO” macro that automatically extracts the appropriate information from the DXKeeper log.

3. PSK63 support

4. rapid switching between PSK and RTTY

5. one-click Main window MMTTY profile selection (standard RTTY, fluttered signals, multipath, etc)

6. one-click upload to

7. broadband decoding

When broadband decoding is enabled, WinWarbler deploys 47 “monitor channels” across the current PSK band. Each monitor channel continuously seeks to lock onto a PSK transmission within its range. Text decoded from locked channels can be continuously displayed in a Monitor Channel window, an example of which may be found in . As you can see, WinWarbler automatically extracts callsigns from the decoded text. A smaller Station’s Heard window shows you who’s on the band: . Double-clicking on an entry in either the Channel Monitor or Heard windows will preload WinWarbler’s current receive pane with all monitored information and will initialize the transmit and receive frequencies for an instant call. The parameters that control broadband decoding are all available for tweaking and experimentation.

Enabling broadband decoding does significantly increase the load on your CPU; a 400mhz Pentium is probably the minimum for this mode of operation.

WinWarbler and all other DXLab applications are available via You can review the online help for any DXLab application without first installing the software.

Development of these applications is continuous and user-driven; if you’d like to participate, you are welcome to join the Yahoo DXLabs group via .
