Pianophase
Based on the first section from Steve Reich’s 1967 piece Piano Phase.
“Two pianists repeat the same twelve note sequence, but one gradually speeds up. Here, the musical patterns are visualized by drawing two lines, one following each pianist.”

Reverse beacon network
A network of Internet connected CW skimmers that display detected signals in real time.
Send a CQ and immediately get a list of reverse beacon stations that heard your call, from around the world, with time and signal report data.
Logs are collected in a database that is accessible for research.

SDR Panadpter, logger, and skimmer
With a TenTec Eagle transceiver, Managed by N4PY software.
N4PY acts as router, distributing CAT commands to other applications.
The applications are connected using virtual serial port bridge pairs. For each of the applications, N4PY emulates a K3 transceiver on one side of the bridge.
- Panadapter: NAP3
- Logger: N1MM
- CW Skimmer
The CW keyer is a K1EL Winkeyer USB controlled solely by the N1MM logger.
The routing of IQ signals from LP-PAN2 SDR is done through a MOTU 828 mk3 interface, simply to be able to split the signal so that both NAP3 and CW Skimmer can use it.
CW Skimmer gets the IQ signal directly from the MOTU. NAP3 doesn’t not recognize multiple ports on soundcards. So one end of the split from the MOTU is sent through another audio interface (Focusrite 2I2). NAP3 uses the 2I2 as an input device.
LP-PAN frequency adjustments
Notes on configuration for correct zero-beating.
When setting the Eagle BW or PBT, the IF will shift in frequency, so the numbers below assume a centered PBT and a BW of 700.
The sidetone pitch is 523 Hz.
Settings may also depend on which roofing filters are installed in the Eagle.
NAP3 settings
Set the global offset to -8200. Leave everything else at 0.
CW Skimmer settings
- CW pitch: 523
- Audio IF: -7520
- Sample rate: 96 kHz
- Hardware: SoftRock-IF

Virtual serial ports in Windows
Using Virtual Serial Port Manager
Setting a local bridge to connect the 2 virtual serial ports allows a Max patch to communicate with a radio on a real serial port and pass through the data to a virtual serial port that can be used by another program, such as a logger. The patch looks like this:
Its looks like a feedback loop but its not. In this case the bridge is: com1 <-> com2. Com1 is port a in the above patch. Data sent to com1 can be read from com2 and vice versa.
Soundjack
Low latency open-source VOIP system for music
By Alexander Carot
I have run Soundjack as a one-way system for sending audio from a shortwave radio over the internet. It has worked well with Windows 7 and Mac OS 10.x. The Windows version requires an ASIO audio interface.
