Ham2K Portable Logger vs AetherRF Lite

The best app to log your QSOs on the go. Support for Parks On The Air (POTA), Summits On The Air (SOTA), Field Day, Winter Field Day, Worldwide Flora and Fauna (WWFF) and more. Fast and efficient yet fully-featured: QRZ.com name lookups, QSO Maps, offline data files, contact rates, duplicate warnings, POTA spots, search parks nearby or by name, etc. See https://www.ham2k.com/legal/terms-of-service/

Aether Lite is an RF and Microwave engineering suite for professionals, students, and enthusiasts. Explore the full RF design workflow — from system link budgets to impedance matching — at no cost. Aether Lite limits the number of blocks in a budget to 3 and the number of budgets in a project to 2. A full-featured version (Aether) without these limitations is also available. System Budget Calculator: • Cascade Analysis: Chain amplifiers, mixers, filters, and attenuators to compute system Noise Figure, Gain, IP3, and P1dB. • Link Budget: Calculate received power, SNR, and link margin for wireless systems. • Export cascade diagrams as PDF, SVG or draw.io. Filter Designer (limited edition, max 3rd order): • Filter Synthesis: Butterworth and Chebyshev responses. • Filter Classes: Low Pass, High Pass and Band Pass. • Passive LC ladder implementation with frequency and component scaling. • S-parameter simulation with magnitude, phase/delay, and schematic views. IQ Simulator: • Signal Generator: Create CW, two-tone, and Gaussian noise signals, or load IQ data files. • Spectrum, IQ waveforms and constellation visualization. Smith Chart Designer (lite version): • Interactive Smith Chart with schematic editor. • L, C, R, Transmission Lines, and S2P blocks. • Amplifier Design with Gain and Stability Circles. • Frequency sweep and Monte Carlo analysis. Data Explorer: • Import Touchstone (.sNp) files. • Cartesian, Polar, and Smith Chart visualizations. • Marker system and snapshot comparison. Analytical & Transmission Line Tools: • Closed-form models for common transmission line geometries. • Resonator and Attenuator Designers. Export & Share: • PDF reports, PNG/SVG screenshots, draw.io diagrams, Touchstone files. Upgrade to Aether for the full feature set: • No limitations on number of blocks in a budget or budgets in a project • Advanced filter types: Elliptic, Legendre-Papoulis, higher-order synthesis • Trace Designer: Full 2D BEM solver for PCB transmission lines For support or feature requests, please contact us.
