ErcomeR company<\/a>.<\/p>\nI found an error:\u00a0<\/b>the last two digits of hundreds and tens Hz in SSB mode correctly change the direction of rotation of the knob fine tuning, however, the actual frequency varies in the opposite direction.<\/b><\/p>\n
I reported a bug in the company ErcomeR, and they sent an e-mail to the Tecsun company.<\/p>\n
ErcomeR received information from Tecsun that one of the PL-880 integrated circuits had been changed to the one used in Tecsun PL-365; no one checked whether the program was working properly.<\/p>\n
The previous version of the radio made in May 2015 does not have this error.<\/p>\n
Best regards – Pawel Kita, SQ9ZAV<\/p><\/blockquote>\n
Pawel also noted that communicating with Tecsun’s Engineering\/R&D department is quite difficult since all communications are first passed through the Tecsun Sales department.<\/p>\n
I hope that Pawel can keep us apprised of the situation. My Tecsun PL-880 is one of the earliest production runs, so doesn’t have the PL-365 IC Pawel describes.<\/p>\n
If you purchased a Tecsun PL-880 recently, you might verify this as well–please comment.<\/p>\n","protected":false},"excerpt":{"rendered":"
