[Elecraft] My KAT500 seems very sensitive to common mode RFI

I have a Hex Beam and a 40m wire vertical w/ two elevated radials. I have been fighting what appears to be a common mode RFI problem which causes the KAT500 to continuously power cycle as long as the K3 is transmitting. Generally this only occurs when driving my KPA500 amp beyond a certain out

[Elecraft] KPA500 powercycling at higher wattages into KPA500

My KAT500 is getting power-cycled in CW and RTTY modes at various drive levels from the K3 on different bands.  I can run SSB full power with no problems at all, and receive superb audio reports (no hint of RF in my transmissions).  I am thinking I have either an excessive voltage drop on the AC

Re: [Elecraft] Headphone Jack Problem with K1

I have noticed that my LINE IN jack sometimes loses the input signal and I have to apply a slight pressure to get it restored (gently push in on it). It's fine after that unless I move the K3. Does this jack suffer the same issues as the headphone jack too? Sent from my iPhone > On Jan 23, 2

[Elecraft] KPA500/KAT500/W2 order advice needed

the K-Line gear. I picked the 0.1-200W directional coupler as I wanted to put the W2 between the K3 and the KPA500. Is it worthwhile adding the second coupler for 1-2000w? I'm assuming you only use this if you want to place the W2 after the KAT500? Thank you all for any suggestions! Jeff H

Re: [Elecraft] VFO B receive not heard in headphones with SUB on (SOLVED!)

Mike, thank you very much! The problem was as I suspected, operator error! The outer AF knob was fully counter clockwise. Restoring this knob to the 12:00 position restored VFO reception in my right ear. It must have gotten knocked by someone using my rig at Field Day. What a relief! 73, Jef

[Elecraft] VFO B receive not heard in headphones with SUB on

I haven't used my K3 much since Field Day. Today I turned it on and engaged the sub receiver by tapping SUB. Instead of hearing VFO B in my right ear, I only hear VFO A in my left ear. Adjusting the SUB RF control affects VFO A volume. It's like the radio's sub receiver configuration got mes

Hi everyone, I need advice on picking filters for a KRX3. I currently have the following filters in my K3: 2.7 kHz 5 pole 1.8 kHz 8 pole 400 Hz  8 pole Should I put the same filters in the KRX3? At this time, I don't have the capability to take advantage of "diversity receive".  It's been a w

[Elecraft] Is it normal for RF meter to occasionally exceed set wattage?

Hi, I noticed during the CQ WPX RTTY contest that often the RF meter was fully pegged with the power set to 100 (the last two bars past the 100 mark). Shouldn't it be lit only to the 100 mark? I did all the calibration procedures when I originally built the radio back in March 2010. I just upda
