[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 t

[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 the

[Elecraft] K4 and Remote Rig

While K4 traffic here has been steady and voluminous, I don't think I've seen anything on how a K4-->RRC1258-->K3 remote setup might work ... if at all ?? 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County __ Elecraft mailing list

Re: [Elecraft] Smoke detectors

The smoke detectors we have here are wired into the security system - no replaceable batteries - except for one which is standalone in the bedroom and was required to be added by the inspector when we built the house even with the whole house system in place. No RFI problems observed. We do kn

Re: [Elecraft] Smoke detectors

For what it’s worth, the American Red Cross is recommending installation of units that have 10-year lithium ion batteries which are sealed and not replaceable. History has shown that kids tend to remove the batteries for their toys and games. They also say the test button tests only the batt

Re: [Elecraft] Smoke detectors

Exactly. Here in Folsom, Sacramento County, we are required to have wired smoke detectors AND battery powered carbon monoxide detectors. In fact, we had our roof replaced a few years ago and the building inspectors would not pass it unless those carbon monoxide detectors were installed. For back

Re: [Elecraft] Smoke detectors

It's important to understand that these safety codes are LOCAL -- usually by state, but also by county and/or city. There are "guideline" codes, like the National Electric Code, that are adopted by most local authorities, and those guideline codes are updated every few years. Often the local co

It's really sad to see how some companies prey on people who don't have the knowledge or the experience. This is only one example! Bert VE3NR On 2020-10-30 13:31, Jim Brown wrote: On 10/30/2020 3:43 AM, N3ALN wrote: HI, I get this kit from Palomore for the K3 and I got another for my Yaesu Qu

Re: [Elecraft] HI CUR on 40

Ferrites are probably not the answer here. Problem showed up with no changes in configuration, and problem happens with a dummy load. Plus I have ferrites in most of those locations already. This only happens on 40 meters and happens both with antenna connected and when dummy load connected. On Fr

Re: [Elecraft] Response time for tech support??

Stan; Please elaborate - what voltage is the HV dropping to? We set up the factory-build units for the voltages at the factory. What you encounter might be different, so you will need to go through the adjustment exercise described in the manual on page 6 of the rev C3 manual (it might have mo

I received my new factory-built KPA500 last Thursday and unfortunately it has a couple of problems - loud chassis buzz on CW and HV drops out of acceptable range with less than 10 watts drive. I sent an email to supp...@elecraft.com a week ago today and then follow

[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. -- Se

Re: [Elecraft] HI CUR on 40

I was getting this HI CUR message to and it was driving me CRAZY! I called Elecraft and I was going to send my K3 back to them and then I saw a few YouTube videos and I installed a TON of toroids on the K3 and Amp and every wire in my shack and no more HI CUR message. Best of luck! -- Sent from:
