A new Red Brick 70A ESC (including BEC) was received and checkout performed to select a SImonK module to load.
NFM has been updated to v1.18.0.
It includes for user convenience, a noise measurement uncertainty calculator based on the discussion of uncertainty of the noise sampling process at (Duffy 2007b) and the calculator at (Duffy 2007c)
Folk often ask for instructions for assembly of so-called clamp type coax connectors.
This article shows such an N type connector, but the techniques are applicable to different connectors with the same type of cable / braid attachment. Continue reading Assembling clamp type coax connectors
COMP_PWM is an option on SimonK ESC firmware for sensorless brushless DC motors (Kirby 2011),
This article looks at the current waveforms resulting from that implementation, and is an expansion of (Duffy 2014).
An article in a series documenting measurements on an IC-7410.
This focuses on receiver Tx power and SWR meter.
Much is written about the virtues of some types of coax connectors over others.
TuneMate is an accessory for Icom radios to make tuning an external ATU faster and more convenient. Continue reading Tunemate update
W5WSS describes his antenna at (eHam 2014). It is essentially a shortened dipole with capacity hats for 20m.
The configuration appears from several postings to be this shortened dipole with a Balun Designs 1115du balun at the center and an adjacent LDG Pro 200 automatic ATU.
