- 160/80m Coaxial Receiving Loop Antennas
- Receiving loop antenna for top band. This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter. And made of light weight material. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable.

- NFM - noise figure measurement
- NFM (for Noise Figure Meter) is a software application to assist Noise Figure measurement. NFM implements the method of Agilent application notes AN 57-1 and AN 57-2 for noise figure measurement, but with the addition of an adjustable attenuator after the noise source and between the DUT and instrument.

- Spectrum Analyzer Real-time FFT
- Eight-channel Audio Spectrum Analyzer is a set of Real-Time Multi-Channel Gauges for investigation of data accepted from any ADC you will want or 16-, 24- and 32-bit ADC of sound card. WDM drivers support. FFT Spectrum Analysis, OscilloScope, Frequency counter, AC/DC voltmeter, Signal-to-Noise Ratio, Signal-to-Noise and Distortion, Spurious-Free Dynamic Range, Effective Number Of Bits, Total Harmonic Distortion, Inter-Modulation Distortion, Phase Shift. Special modes of dual-channel FFT spectral analysis: Separate channels spectra, Spectra of digital sum, difference, product of two signals, Spectrum of digital product of original signal and its fundamental, Spectrum of Real and Complex Transfer Function, Cross Spectrum. Standart weighing of spectra according IEC and CCIR. Oscilloscope modes (for dual-channel ADC) are: original signals, sum, difference, dependence of one channel on another, amplitude distribution of input signals.
