Andrews Communications Systems - Australian dealer, HF linear amplifiers, power supplies, baluns, HF UHF yagis and verticals including multiband HF verticals.

Minnesota DX Club - The MDXC has monthly meeting in the Twin Cites. Coverage all bands from LW to UHF. We also have Summer and Winter DXpeditions.

ASAP - A Free general purpose antenna analysis user-oriented software program for numerical electromagnetic antenna design, antenna modeling and antenna analysis.

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.

Voice Descramble - This program descrambles band inverted encrypted transmissions, usually found on VHF/UHF. It uses a NCO (numerical controlled oscillator) to re-produce the originally inverted audio band.

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.).
