I have 24xx K3. It did need the mod. Actually put in when I had a LP pan-adapter before the P3. The mod is changing one resistor. R8 from 1k to 13k. I used a 1/4 watt only because I do not stock 1/8 watt.
On the Elecraft web site K3IOBUFFKT - IF Output Buffer Gain Modification is the kit for $5. https://elecraft.com/pages/k3-enhancements-and-mods-and-tech-alerts The instructions are https://ftp.elecraft.com/K3/Mod%20Notes%20Alerts/IF_Output_Buffer_Gain_Mod_Rev_A.pdf The mod sheet says all K3 shipped after September 2009 have this mod. Hopes that helps a bit 73 George Danner -----Original Message----- From: [email protected] Sent: Thursday, February 20, 2020 10:00 AM To: [email protected] Subject: [Elecraft] P3 Goodness and questions I recently obtained a P3 and I'm and exceedingly happy! Now that I own it I feel bad that I wasted a few years trying other solutions that introduced noise and undue complexity into my station. Just a few notes and questions because the manual is helpful but I don't fully understand what I'm reading yet. 1. When using QSY the P3 unit often slides. How do most of you prevent the unit from sliding? 2. The signal/noise floor jumps a lot and I'm not sure if that's due to local interference or something in my setup. Based on reading I likely need to noise troubleshoot/filter my station. I don't see an AGC setting for the P3. Any suggestions? 3. What serial number requires the mod? My serial is 3251 4. I need a serial port screw stud - can I buy that from Elecraft when I purchase a cable + vga card? 5. Is there a quick setup cheat-sheet anyone has for the P3? Thanks in advance Jerry Moore AE4PB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
