JARL QRP CLUB #647 ７L2VPL

2000年以来MIZUHO製の機器や自作機器での交信をして来ました
無線活動が停滞気味の局免許更新時に新スプリアス規制が重なり年代物の無線機器と自作機器は使えなくなるものと誤解して局免許の更新時にQRP機器の全てを削除してしまいました　スプリアス規制の下で旧QRP送信機の増設申請は簡単ではないと思いますが自作機器を再度使用してみたいので移動局免許への増設申請をしていこうと思います

I've been using Mizuho equipment and homemade equipment for QSOs since 2000. My radio activities have been somewhat stagnant, and when it came time to renew my station license, the new spurious emission regulations came into effect. I mistakenly thought that my older radio equipment and homemade equipment would become unusable, so I deleted all my QRP equipment when renewing my license. I know it won't be easy to add old QRP transmitters under the spurious emission regulations, but I'd like to use my homemade equipment again, so I'm going to apply to add it to my mobile station license.

メーカー製の高性能なリグでの交信は快適ですが自作QRP機器での交信はそれとは違った楽しみがあります　７MHzの受信機はDCRXです　これにFCZ Lab.の#164 CW AUDIO FILTERを通しLM386のスピーカー付き低周波増幅器で聴くわけです　送信周波数の確認は吸収型GDMで表示させるか　周波数カウンターの入力ケーブルをANTケーブルに沿わせて表示された周波数をチェックします　色々な自作機器を総動員して交信する訳です　CW信号を受信してゼロビートを取ります　BFOで受信周波数の上下にビート音が聴こえます　その中心の音のならない場所にダイアルを合わせるのです　次にその受信周波数に送信周波数を合わせます　キャリブレスイッチをオンして送信機のVXOダイヤルを回し受信機のスピーカーでゼロビートを取れば送受信周波数は一致です　後はLITで受信周波数をずらして聴きやすいCW音に調整すればコール準備が整います　やたらに面倒な操作ですが　これが楽しいのです　

While communicating with high-performance, commercially available rigs is comfortable, communicating with homemade QRP equipment offers a different kind of enjoyment. My 7MHz receiver is a DCRX. I connect it to an FCZ Lab. #164 CW AUDIO FILTER and listen through an LM386 speaker-equipped low-frequency amplifier. I check the transmit frequency by displaying it with an absorption-type GDM or by running the frequency counter's input cable along the antenna cable and checking the displayed frequency. I mobilize all sorts of homemade equipment to communicate. I receive the CW signal and take the zero beat. With the BFO, I hear beat sounds above and below the receive frequency; I adjust the dial to the center where there is no sound. Next, I match the transmit frequency to that receive frequency. I turn on the calibration switch, rotate the transmitter's VXO dial, and take the zero beat using the receiver's speaker, and the transmit and receive frequencies match. Then, I use the LIT to shift the receive frequency and adjust it to a pleasant CW tone, and I'm ready to call. It's a ridiculously complicated operation, but that's what makes it fun.
