Winter VHF Sprint Contest

************************************ Winter VHF Sprint Sponsored by the Rochester VHF Group RVHFG.org ************************************ 0 Purpose: Contact as many stations on as many VHF (30-300 MHz) bands as possible within a ONE HOUR period. I didn’t plan to participate in the Winter sprint contest since there was another major ARRL Roundup RTTY contest going on same day. […]

160m QRV from HOA

Hello. Finally I was able to operate on 160m band from my small lot in HOA community. I already had all bands coverage, but 160m was a bit challenge. Now it’s a the good season for 160m band DXing and FT8 mode gives a lot of opportunities for it. Most of activities on low bands […]

Western Samoan Adventure (5W0NA)

On September 28th I arrived to Apia, Western Samoa which is located in south Pacific. It’s very beautiful place and I can compare it to Hawaii. I was a member of ZK3A DX expedition to Tokelau and Apia was our meeting place for all members before departure to Tokelau islands. The total flight time from […]

2m Band Crosses Polarized Yagi

Previously I’ve posted article about crossed polarized yagi for 435MHz made from two single yagi antennas. It was a budget version of antenna for satellite communications. I also described how to connect two antennas and combine into one cable. This time I modified 145MHz antenna in same way. That allowed me to increase gain and […]

ARRL DX 10M Contest

This was the first contest using IC-705 transceiver. I had a blast working QRP from new IC-705. Propagation was not good but I managed to make 70 QSOs only in CW. For SSB working QRP without propagation is no pleasure. My contest setup was:1) Icom IC-7052) HEX Beam antenna (2el for 10m) This is scores: […]

CQ WW CW 2020

Lately I was extremely busy at work and home. It’s hard to find right amount time to enjoy amateur radio especially when have two kinds. But I always trying to participate in any contests only for fun, not for results. I love competition but at this time is impossible plus I live in HOA with […]

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.
