[Elecraft] [K2] CAL-PLL Question
Don and Dave, thanks for the responses. The idea with the ground contacts is interesting. Regardless of whether it makes a difference, I will check and clean the contact surfaces once the next time I open the base plate. I have not paid attention to this detail before. 73, Wolfgang DL2KI -- 73 de DL2KI http://www.dl2ki.de DOK K08 DL-QRP-AG #3247 G-QRPC #13541 AGCW # 3944 HSC #1970 GnuPG: Öffentlicher Schlüssel erzeugt am: 2012-10-27 Key-ID: 0xFB3F3B7A Algorithmus: RSA(4096 Bit) Fingerprint: 4530 9FCB 9D48 9B50 967C F81C 0EDB 78D9 FB3F 3B7A Anleitung - E-Mails verschlüsseln - Free Software Foundation https://emailselfdefense.fsf.org/de/ __ 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] [K2] CAL-PLL Question
The only reason I can think of why this might apply is if the grounding of the bottom cover was poor. Whilst it certainly can be poor, because of paint not having been properly masked around the mounting blocks, and I recommend cleaning all paint off, around them, I'd be surprised if enough of the induced currents, in the bottom panel, flowed through these points to make a difference. -- David Woolley Owner K2 06123 On 30/07/2022 16:25, Wolfgang wrote: in a german QRP forum I found this hint from Peter, DL2FI (SK).

Re: [Elecraft] [K2] CAL-PLL Question
Wolfgang, In my experience, that is not necessary. It IS necessary to have the bottom cover in place before running CAL PLL. 73, Don W3FPR On 7/30/2022 11:25 AM, Wolfgang wrote: Hi, in a german QRP forum I found this hint from Peter, DL2FI (SK).

This statement does not correspond to the instructions in the K2 manual and other contributions here. Also, I can't understand the reason behind this statement.

Since Peter is SK, I can unfortunately no longer ask him myself. 73, Wolfgang DL2KI __ 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
