MTR-5B

KD1JVの今朝(JST)の投稿によると、15mにはスプリアスの問題があることが判明したため、15mの代わりに80mを採用するとのこと。
よって、80/40/30/20/17mの5バンドとなる。

6/8追記: 15mのスプリアスの問題は解決したとのことだが、バンド構成(40/30/20/17/15m or 80/40/30/20/17m)については言及はない。

6/14追記: マニュアル(ドラフト)によると、40/30/20/17/15mの5バンド。また表示部は、ATS-3シリーズやこれまでのMTRシリーズの7セグとは異なり、ATS-4シリーズのようなキャラクタ液晶(16文字×4行)となっている。

6/25追記: リリースは来月の予定。80mも対応可能(この場合はおそらく80-15mではなく80-17m)だが、部品は提供されない。

GOTA - Gardens On The Air

SOTA (Summits on the Air)が有名だが(もっとも一番有名なのはIOTAだが)、このたびClub 72によるGOTA (Gardens on the Air)が始まった。

Club 72 Newsより:
new QRP project started in the Club 72.
GOTA - Gardens On The Air.
See details at the Club 72 page - www.club72.su
Welcome to take a part in GOTA!

Club 72のGOTAページより:
QRP activity in the garden position only. QRP output power only, around QRP frequencies, only temporary antennas and off-line power supply. In the report ass "GOTA" identification, WW-locator, output power and antenna type. As additional you can report about your current garden occupation, e.g. cucumber, potatoes, to dig, roof repair, BBQ etc. Form and size of additional information in accordance with QSO situation. Keep a humor sense! 1 QRP QSO = 1 point, 2-way GOTA QSO = 3 points. Send log and photo to "mr72" e-mail, please.

普段からGOTAのような運用をしていると、被災時等には有効かもしれない。


また、POTA (Parks on the Air)というものもある。
The rules for activating are simple:
・A minimum of five contacts on any amateur-radio band, using any mode (if using FM on VHF or UHF, simplex only), made since Sept. 15, 2010.
・Use any power level allowed within the terms of your license.
・Contacts can be made over several visits to a park, although experience shows that you often can make enough contacts between lunch and dinner to meet the five-contact minimum.

Youkits HB-1B MK3

Youkits HB-1B MK3 4 band QRP CW transceiverがアナウンスされた。
これまでのHB-1Bは80/40/30/20mの4バンドだったが、MK3は40/30/20/15mの4バンド、さらにフィルタを15mと兼用しているために感度は落ちるが、17mにも対応している。
出荷開始は5月25日頃、価格はこれまでと同じ299USD(バッテリーと充電器も含む)の予定。

Hendricks QRP Kits売却

http://www.qrpkits.com/
I would like to announce that Hendricks QRP Kits has been sold to James Bennett and Kathy Long of Pacific Antenna
and we have started the process of transitioning company operations.

I will still be involved with the company as a consultant and they will be managing the day-to-day operations as the new owners.

I enjoyed running Hendricks QRP Kits but it is now time to move on with full retirement. I would like to thank all of the customers and wonderful QRPers that I've met through the past 10 years of my business ownership

Stay tuned to this website for further announcements. The target date for reopening is April 1. Doug
