SWR stands for “standing wave ratio” and is a measure that can be used to tune an antenna for a particular frequency. The closer the SWR is to 1:1 at the designed antenna frequency, the better the antenna will receive (and transmit). In his video Adam shows how he measures the SWR of an ADS-B antenna which he

The closer the SWR is to 1:1 at the designed antenna frequency, the better the antenna will receive (and transmit). In his video Adam shows how he measures the SWR of an ADS-B antenna which he Over on the swling.com blog (short wave listening) contributor Guy Atkins has posted about his comparisons of the Airspy HF+ and the Elad FDM-S2 SDRs on the Medium Wave band.

A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously.SDR technology makes it possible that all listeners tune independently, and thus listen to differentsignals; this is in contrast to the many classical receivers that are already available via the internet.

SWR or Standing Wave Ratio is a measurement of antenna efficiency. Showing high frequency (HF) (or Medium Wave) AM broadcast radio being received with the RTL SDR RTL2832 dongle.

Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave 's amplitude at an antinode (maximum) to the amplitude at a node (minimum) along the line. SWR stands for “standing wave ratio” and is a measure that can be used to tune an antenna for a particular frequency. The closer the SWR is to 1:1 at the designed antenna frequency, the better the antenna will receive (and transmit).

Is this a drawback to the IC-R8600 ? Strongly NO. Being this is a true SDR (on HF), this is the just part of the technology at this price point. The IC-R8600 does NOT have the "MW band ATT" setting in the Menu's as with the IC-7300. Long Wave (LW) performance is MUCH improved over the IC-7300 transceiver (in fact it's night and day).
