Introduction to the Icom IC-7300

Chris Ridley (G8GKC), Bob Rogers (M0KKW) and Ian Lockyer (2E0IAJ) from Icom UK give an overview of the IC-7300 HF/50/70MHz transceiver, Icom's first Software Defined Radio (SDR) HF radio.

Super J-Pole Antenna for the 4m

Super J-Pole Antenna for the 70Mhz (4m) Amateur band.
The Vortex ‘Super J-Pole’ Antenna consists of a five eighth wave vertical radiator, a half wave tuning section and a half wave top section. At the base, a quarter wave matching stub forms the classic ‘J Shape’. The addition of the extra half wave top section boosts the gain over a standard J-Pole. The Super J-Pole has an added advantage that tuning can be varied over a fairly wide frequency range by moving the feed-point location up or down. This also gives the user finer control over the impedance and match. The antenna is end fed and has an omni-directional radiation pattern and requires no ground plane or radials. The antenna has a nice low angle of radiation, typically 8 degrees when mounted at 4m in height. This angle reduces further the higher the antenna is mounted. A typical installation with the antenna at 8 meters above ground sees the angle reduce to 5 degrees and the gain increases to 7.29dbi when ground reflections are added.

WiFi Wireless Ham Radio Coax Antenna Switch

WiFi Wireless Ham Radio Antenna Switch allows a single transceiver to switch 4 antennas. Free iPhone app on Apple Store. TCP control.

FREE CONTROL iPHONE APP ON APP STORE: ANTENNA SWITCH The WiFi Wireless Ham Radio Coax Antenna Switch 82664XAS01 allows a single transceiver to switch between 4 antennas or 4 transceivers to switch to a single antenna. Full configurable via a web browser. The switch responds to TCP commands. It can handle up to approximately 250 Watts and covers frequencies from 0 to 150 MHz. Control the switch with a free iPhone app AntennaSwitch switch available now on the apple store The switch comes with 2 separate boards: the control board and the connector board. Both boards are connected together with wires. Screw connectors are provided. The WiFi wireless antenna switch allows switching from 4 different antennas into one output to the transceiver. I can also be reverted so 1 antenna can be switched to 4 different transceivers. The switch module can be mounted on a box for convenience and safety. The module is controlled via the simple TCP commands 1, 2, 3 and 4 to switch between the 4 different inputs. Once the module is configured and acquires an IP address, commands can be sent to its IP address and port 9999 to switch between the inputs.

Yaesu Rotor Controller Az. Insert

CQmaps - Professional Maps for Amateur Radio, is extremely happy to offer the Amateur Radio community a truly helpful station aid for your Yaesu line of Rotor Controllers. Many of CQmaps' customers had been asking for an Azimuthal Projection Insert Map for their controllers and we answered! Your Great Circle map will feature the same 4 inch diameter world view as the dial of the controller. Since the map is centered on your qth, dialing in your DX just became much easier.
