[Elecraft] K2 Hum seems to be sorted

Hi, The issues with Hum seem to have been sorted. I did some tests with a few stations, and a ZL and they indicated my CW transmissions are as clean as a whistle. I think that problem may have been some RF in the shack. Never mind... it gave me the morning to run around and get the panels off

[Elecraft] Elecraft K2 hum on CW

Hi folks, I recently posted about my raspy CW audio on the K2. It is most evident on 20 and 40m. My shack is grounded. Today I replaced the RFC15 just to make sure that wasn't the issue. I have removed the KPA 100 and returned the QRP lid. The issue still exists. Any suggestions to clean

[Elecraft] CW Hum on 20m

Hi, I noticed last night i have a raspy hum on CW and SSB when transmitting on 20m. The other bands seem to be fine. Has anyone else encountered this? I have searched the archive and another person experienced the same but I can't see if the operator found a solution. Cheers, Dave. --

[Elecraft] Removing KDSP2 and reinstalling KAF2

Hi, I am wanting to reinstall the KAF2 to my K2. It appears from the KDSP2 manual it would be a simple procedure to plug it into the radio. However, I recall some parts or jumpers had to be made for the KDSP2 to be installed. Has anyone got the link to the instructions on how to reinstall the

[Elecraft] KPA-100 pop from TX to RX

Hello everyone, I have just reconnected my KPA100 and I have a pop from the speaker when the transmit switches to receive. I checked most settings including that my 8r hold is set as per the manual. I do notice that when I set 8r normal the pop disappears. What's the go here? The other issue

Re: [Elecraft] KPA-100 pop from TX to RX

Thanks Don, I will check the parts mentioned. I also have a feeling I may have some common mode currents interfering a bit. I've recently put up a sloper under the hex beam. I need to play with this. The pop on switch to RX is more prominent on the lower bands. When I set the power to less

Re: [Elecraft] KPA-100 pop from TX to RX

Don, I have fixed the mechanical buzz from the SSB tx on the KPA-100. The fault was mine. Across the RF Aux input between the PCB and the heatsink there seems to be a blue resistor with the colours Brn-Blk-Blk-Org-Brn with one leg that was touching the heat sink. The legs are long and so I

[Elecraft] Low Power on K2

Hi folk, I've dusted off my K2 and decided to QRP OP on CW now the bands are up and running. The RX is perfect and filters alignments and freq cal is spot on, or near perfect. Since I've had this radio the Max power output on 20 - 10m has been well below 10watts. In fact I can only get 5 watts

[Elecraft] What became of the Elecraft’s KPA150 0 and KPA 800

What happened to the Elecraft Amps? Did they get beyond 'proto: gee I want one' stage? -- View this message in context: http://n2.nabble.com/What-became-of-the-Elecraft-s-KPA1500-and-KPA-800-tp4528292p4528292.html Sent from the [OT] mailing list archive at Nabble.com.

Re: [Elecraft] PRE/ATT intermittent fault

After how many years? I finally fixed the intermittent sensitivity issue I had with my K2. The problem was not a latching relay but a cap on the bottom of the main board. The legs of this cap protrude under the NB option. I noticed that one of the legs had not been soldered through the hole

Re: [Elecraft] [K2] K2 80m Scratch RX audio

Hi Tom, I sometimes get that on 40mx with my NB on in the presence of strong broadcast stations. If I turn the NB off all is well again. I know this may not necessarily help your situation. Is your distortion all the time? Dave Tom Campie wrote: Hey guys, I'm having a problem with my K2

Re: [Elecraft] [K2] Is the K2 old technology?

Hi Paul, I have had my K2 on air since 2004 and when I purchased other radios such as the PROII I have had to sell them because I prefer the sound of the little K2, and it's performance is as good if not better. You won't be disappointed if you go the K2 route. It can be frustrating if the
