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 […]
Making Crossed Polarized Yagi
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 […]
New Q5 Signal 5 Band Transverter
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
K6VHF’s new QSL card
AMSAT Satellite System installed
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.
New K6VHF’s Shack
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)

Ten-Ten International Net #77458
My Ten-Ten International number is: #77458 I love 10 m band for his outstanding propagation, long distance communication with low power during the high solar activity. Indeed, you don’t need a serious equipment and antennas to start working on 10 m band. Because it’s a top HF band the size of antenna usually small, so […]
K6VHF Soft
EFFECTIVE ISOTROPIC RADIATED POWER CALCULATOR ERPC v.1.02 Very easy to use. Enter RF power, known antenna gain and approximate total cable losses. Click on “Calculate”. The ERP and EIRP results would be on right side. The difference is just reference to isotropic antenna or dipole. Also you’ll be able to convert dBd to dBi. Download ERPC v.1.02 BIAS […]
Radio Mobile Software by Roger VE2DBE
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: […]
The Go-Bag for ARES or Portable Work
This is what I use for my ARES and emergency communication drills as well as for portable work (hiking or backpacking). As you can see it’s a simple backpack that you can find in many sport goods store (for example Big 5). I found that this backpack is perfectly meets my requirements. So what is […]
Portable 3 EL 70cm Band Yagi
Hello. I want to share one of my recent projects – 3 el yagi for 70 cm band. It’s very light, portable and great for backpacking or hiking. I like hiking a lot so to have the necessary equipment is important. For HF bands I have IC-703+ and set of J-pole antennas. Many HAMs use […]
Simple Bluetooth CAT Interface, RX/TX App Android
Hello everyone. Want to share another project for who like spend time with smelling flux and solder. The project is – Simple CAT Interface. I guess everyone knows what it CAT for, no isn’t CAT or DOG. Most of us have the cable CAT interface which we use to control our rig from computer. The […]
