2. LF: Prototype for QRSI (score: 1): Author: Rick Wakatori <[email protected]>; Date: Mon, 28 Jun 2010 13:51:56 +0900; We are now making a prototype for QRSs-Image(here after QRSI) beacon keyer at 137770Hz as shown in a photo. Total frequency shift is about 1.125Hz(F1A). CW tone(A1A) is capable after an imaged callsi; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-06/msg00555.html (11,625 bytes)
