[Elecraft] K3 :: hardware AGC mod kit
I have my K3 on the bench, doing a series of updates and whatnot= ... since I just got and assembled the P3 I figured the setup is disconnected anyway, so, this is a good time. The K3 is serial # 1209. Looking at the hardware AGC mod instructions, I see that my radio does not have an R101 to replace with an LED, but already HAS an LED at that location. The silkscreened reference designator (D40?) is for a diode. R40 and R33 are already low-value ( a few ohms) resistance parts. R41 and R42 are already 33k parts. So... can I assume that this mod isn't necessary on my rig?

Steve, That certainly sounds like the Hardware AGC mod is already installed on your K3. 73, Don W3FPR On 9/16/2010 9:14 PM, Steve Jackson wrote: > I have my K3 on the bench, doing a series of updates and whatnot= ... since > I just got and assembled the P3 I figured the setup is disconnected anyway, > so, this is a good time. > > The K3 is serial # 1209. > > Looking at the hardware AGC mod instructions, I see that my radio does not > have an R101 to replace with an LED, but already HAS an LED at that > location. > The silkscreened reference designator (D40?) is for a diode. > > R40 and R33 are already low-value ( a few ohms) resistance parts. > > R41 and R42 are already 33k parts. > > So... can I assume that this mod isn't necessary on my rig? > > Steve KZ1X/4 > __ 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
