Re: [Elecraft] [PX3] v1.16 Bug?: Cursor in AM mode
Hi Nakamura I think you're right about this but also I think that the lo/hi-cut settings affect the audio and not the "IF" bandwidth. I know that in the Perseus software you can influence both AM sidebands independently and in fact listen to only one sideband plus carrier in both AM and AM-sync and probably you would like to have that option as well in the KX3... The only way I can get this option is by using the KX3's I/Q output, a PC and HDSDR-software. HDSDR toggles in AM-sync between LSB, USB and DSB with a simple click on the AM-Sync button. 73 and Happy New Year, Peter - PA0PJE Op 2014-12-30 05:29 schreef JE0LFI: Hi Alan / N1AL, Hi all AM mode bandwidth indication of PX3 will be inferred that it VSB(Vestigial Lower side band). http://en.wikipedia.org/wiki/Single-sideband_modulation Since using the VSB, will be displayed cursor across the carrier frequency, such like this: _==C=_ : Vestigial Lower Side Band VSB Future, if the SYNC-AM mode is supported, you'll be switching to Vestigial Upper side band. _=C==_ : Vestigial Upper Side Band VSB 73 and Here's to the New Year !

Re: [Elecraft] [PX3] v1.16 Bug?: Cursor in AM mode
Hi Alan / N1AL and all > In AM mode, the bandwidth is mirrored about the carrier frequency. The bandwidth is not mirrored about the carrier freq displayed in PX3. In NORM setting(Low=0.0, Hi=3.0), the PX3 bandwidth is as follows(where C is center): _==C==__ When I set Low to 0.5, the PX3 bandwidth is: ===C==__ So, the PX3 bandwidth is not mirrored about the carrier freq. Expected bandwidth is: ___C____ Is this correct? 73, JE0LFI / Nakamura __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] [PX3] v1.16 Bug?: Cursor in AM mode
The KX3 (and K3) bandwidth controls are with respect too the audio frequency, not the RF frequency. So in LSB mode, for example, the bandwidths move in opposite directions on the KX3 and PX3. In AM mode, the bandwidth is mirrored about the carrier frequency.
