K5BOB Bobber Hex - Bobber Hex Antenna, Made of CNC cut UHMW plastics. Very little metal is used in production of this Hex beam antenna

Scanrec Scanner Recorder - Scanner Recorder (Scanrec) is a free audio recorder that is primarily designed to record speech. It has a VOX control that allows the user to save disk space when no sound is present in the signal. Since FM communications has such an effective squelch, the recorder works best with FM. HF ham bands and World Band radio have such a poor signal to noise ratio that the VOX gate on Scanrec might not be very easy to set.

Vox Recorder  ^{updated  pop} - Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input. Vox Recorder has been designed in particular for radio-scanner hobbists.

Stream - Stream is a software that implements MFSK16 and MFSK8 modes designed by me and Murray Greenman ZL1BPU. It also offers a series of experimental modes based on FEC, interleaving and several modulation techniques (PSK, QPSK, MSK, &c.).

WinPSKse - WinPSKse is a logical outgrowth of WinPSK as designed and written by AE4JY. The look and feel is intentionally similar, but some significant changes have been made, not the least of which is the ability toreceive two PSK31 signals simultaneously.
