Hi, Bill (G4WJS) Thank you for your kind and quick email reply. About 80m band FT4 frequency 3.523MHz and I think Korean DX members are very positive.
We will respond to your opinions in a short period of time by collecting opinions from Korean HAMs. In addition, we request a review to be able to assign the 60m Band to 1.822 KHz or another frequency( ex) 1819 , 1820....) from 1.800 to 1.825 MHz. de HL2WA ( KYU ) http://qrz.com/db/hl2wa -------------------------------------- Without haste , Without waste~~!! -----Original Message----- From: "Bill Somerville"<g4...@classdesign.com> To: "이동규"<hl...@naver.com>; <wsjt-devel@lists.sourceforge.net>; <w5...@gvtc.com>; <k...@arrl.net>; Cc: Sent: 2019-05-01 (수) 19:19:43 (GMT+09:00) Subject: Re: [HL2WA] Request of 80m band review for FT4 frequency On 01/05/2019 08:53, 이동규 wrote: I applaud your wonderful new communication modes FT8, FT4 ... great development. And, thank you very much. For Korea (HL), the operating frequency range of 80m Band is 3.500 ~ 3.550MHz according to Korean Radio Law. When selecting the FT4 frequency, please request to select 3.547MHz or 3.523MHz. If set to 3.567MHz as per the basic plan, no Korean HAM can be used. Once again, I am deeply grateful for your new mode development. de HL2WA (KYU) http://qrz.com/db/hl2wa -------------------------------------- Without haste , Without waste~~!! Hi KYU, thanks for you suggestions. We strive to suggest working frequencies which are globally coordinated, in IARU regions 1 and 2 the band plans mandate CW only below 3570 kHz so it is not possible use frequencies below that worldwide. We do have a capability in WSJT-X to set IARU region specific working frequencies and for 80m we currently propose 3570 kHz as it is suitable for JA operators being within their licensed allocation. Looking at the HL band plan it seems that 3523 kHz is better than 3547 kHz because it is within the 3520 - 3525 kHz digital modes section. I note that 3525 kHz is designated as an emergency communications frequency, I assume this is LSB, will that cause issues if we suggest 3523 kHz USB for FT4 operation? 73 Bill G4WJS.
