During VHF/UHF and Microwave contests K6VHF most of the time operates as rover station. His rover station contains following equipment: IC-9700 (2m,70cm,23cm) IC-7300 (6m and 10m for transverters) IC-705 (used for transverters) Q5 Signal 5 band transverter FT-857D (backup rig HF+VHF/UHF) TM-D710 (APRS+FM) IC-37A (223MHz FM) DJ-G29 (220/900MHz FM) Kunhe 2304 MHz transverter + 30watts […]
As all you know for successful communication via Amateur radio satellites the antenna system should have both polarization capability. That’s for very simple reason – Faraday effect. Faraday effect is a rotation of the plane of polarization of electromagnetic waves in certain substances in a magnetic field. So for all moving and rotating objects that […]
Recently I’ve purchased 5 band transverter from Q5 Signal, LLC. It’s so convenient to have for VHF/UHF contesting/rovering. It covers most of band that you need. No additional radios other than simple 28MHz transceiver required. In my case I use Icom IC-705. More info regarding Q5 transverter can be found http://q5signal.com/index.php?route=product/product&product_id=99 Alex K6VHF
Finally I found time to install a satellite systems with automatic tracking. I use Icom IC-9700 as a main rig and S.A.T controller for tracking. Antennas are: 2 x 10el crossed polarized 435MHz 2 x 4el crossed polarized 145MHz Rotator system is Yaesu G-5500.
This is how my shack look like. I updated and simplified it. Also arranged radio for comfort. Now my shack contains: ICOM IC-7300 HF+6m ICOM IC-9700 VHF/UHF/Satellites ICOM IC-705 HF/VHF/UHF second radio ICOM IC-2730A VHF/UHF FM Local SPE Expert 1.3KA Amplifier 1.5kW Noise Cancellation Device (HF)
Everyone who like VHF/UHF and contesting on this bands must know about this free tool. Yes it’s completely free to use but required a registration. The website is here and a desktop version is here Basically it’s tool that helps to predict and calculate a radio wave propagation on amateur bands. Let’s read more about: […]
