    Home Elecraft K4D Noise Reduction compared to BHI NR module

    Have any of the more recent K4 updates improved the NR? The one thing that disappoints me about my K3 after 15 years is the useless NR on voice. I'll put the poor autonotch at #2. I am fortunate to have a rather low noise environment but there are times when a functioning NR would be useful.

    Big switching power supplies - what's the forum favorite?

    I've an Astron RM-50M under my desk. It does the job year after year. No RF hash and no fan noise. I detest fan noise, especially if it is continuous. Some switchers are temperature activated while others run the fans continuously. Those that have a tiny fan may sound like they're ready for...

    Why 160m Rarely Appears in Band-Condition Charts

    It's not quite that bad. I hit on a formula a number of years back that has served me well. I use a center fed doublet that is about 3/8 wavelength on 160m (approximately 205 feet) and fed with 450 ohm window lead. In its current iteration the center is at 40 feet and the ends nominally 25...

    Any updates because I've not seen anything about any proposed changes.

    Why 160m Rarely Appears in Band-Condition Charts

    It seems like the past couple of years that 75m has been quite poor during the midday due to high D layer absorption.

    The New FTDX10 Compact HF/50MHz 100W SDR

    I'm leery of Yaesu. The HF rigs made in the late '80s/early'90s were superior to the ones that came later in terms of receiver performance. I had the joy of operating an FT-990 several times. Loved that radio. When I went looking for something in 2000 my choice was between finding a clean...

    No more free ham ticket?

    I doubt that it will work that way. From what little I've read the proposed admin fees will be in addition to the existing regulatory fees. Remember, the FCC is just following the legislation that bound them to doing this. Of course they can't just come out and say that any amount less than...

    How I became a ham

    Nice memories, Nandu. Something about the magic of hearing the voice of another over a distance with nothing but air between us keeps us interested for the rest of our lives. :)

    grounding rod question

    Cut it off, go out 8 feet and drive the rest of the rod. We did this for a commercial site years back that had a limestone ledge almost exactly four feet down. We did this for about three or four rods and went out a ways from the site compound as a result. Here I have a ledge about seven feet...

    Problem with a mega watt PSU S-700-12 50 Amps

    Thanks, it's nice to know I'm a "bad customer" because I bought a product in good faith and when I was seeking a solution the seller goes radio silent. :rolleyes: I'd point you to the review I posted but I'd likely be called a liar too regarding the audio level of the fan as soon as I plugged...

    Problem with a mega watt PSU S-700-12 50 Amps

    Sounds par for the course. After being told how fantastic these supplies are from him and others when I expressed interest in purchasing one, when I expressed my dismay on the audible level of the fan he went incommunicado in short order. At least MFJ has a "no matter what" warranty. :whistle:

    Id like some help looking for a pair of 2 meter 70 cm radios,pre heavy menu driven

    They're there. You gotta do a mental diff to find it since it was written inside the quote tags.

    Id like some help looking for a pair of 2 meter 70 cm radios,pre heavy menu driven

    Thing is with pre-menu Yaesus is that they're getting long in the tooth. The FT-5200/5100 series is nearing 30 years old and suffer from display bulb burnout and other assorted issues. I replaced the PA modules in the '5100s I had a couple of times. The FT-8100 I have is over 20 years old and...

    How close will nvis work?

    At higher solar flux values NVIS works on 40 quite well. It all depends on the value of the Critical Frequency. To answer the OP's question, NVIS will probably be the most reliable between the two of you on 75/80m with antennas at about the 25-50 foot range at the apex and sloping down to...

    Ham Radio Testing - How will it be handled?

    While I promote the availability of exams, it has been a few years since anyone actually wanted to take one locally, so nothing has really changed here.

    Are SDR radios worth it or is it all hype?

    There is value to the SDR as well as limitations. I have recently acquired an SDRplay RSPdx and an RTL-SDR.com v3 dongle. I am primarily using them with Linux using Cubic SDR. I find the RSPdx will overload from the local AM (250 Watts, 8 miles away) and FM (20 kW or so about 5 miles away)...

    Amazon Drones - possible interference?

    Well, if one will drop off a misdirected K4 on my place, I won't mind at all! Of course, Amazon won't be handling Elecraft shipments and I'm too far out in the sticks so they'll stick with UPS.

    Nascar hasn't changed

    I probably shouldn't even get started on the farce that was the demolition 500 on Sunday. That was beyond stupid.
