I have attached a link the has information on some of the items that I have designed that may be of interest to the group that will enhance your listening experience on the bands. ?Everett

Lowest (1:1) SWR is the point where the highest level of power transfer occurs between the source and the load. Not sure what an AlexTune is though John [email protected]> wrote:

Not sure but maybe the AlexTune is detuning the antenna slightly. Try running the NanoVNA with the AlexTune clipped on there and see if the Nano results are

The NanoVNA and your xcvr is telling you at what frequency the loop is exhibiting nearest to 50 ohms resistive. The AlexTune is showing the frequency of maximum power transfer, indicating the the o/p

Hello all, I'm clipping an AlexTune ( http://alexloop.com/artigo41.html ) onto a W2LI magnetic loop antenna. I'm puzzled by something: the point at which it shines brightest is consistently about +20

Dear people, What a great quick support offers from you. I have made a deal with Matt to help me getting those PVC boxes. Those, together with my own Alu bending machine and the N4CY PCB which fit

Hello Michael Yes they are still commonly used and a Google search on "20mm 2 Way Through Junction Box - White" brings up plenty of them, much cheaper than the one that you list. For

Did anyone mention CPC? may also be available through Farnell their parent company. https://cpc.farnell.com/pro-power/cjb20-2w/2-way-through-box-20mm-white/dp/CBBR1868 73 Nick

It seems that the exact Schneider part is also available

I would be happy to post you some of these if you cover the cost. https://www.screwfix.com/p/deta-tte-2-way-20mm-through-box-white/299vt Matt M0LMK KI5GXV

Hi, Jorge here (M0LDW...also LW5DX) in Leeds. I found them in different variants in Amazon UK. I don't think there will be an issue with the stock. The way to search is looking for: "20mm Conduit 2

Dear UK ham, I am building my Wellbrook copy with the PCB from Everett. This PCB fits into the original enclosure: 20mm 2 Way Through Junction Box - White. Unfortunately it is out of production with

Francesco, that label means the maximum RF and DC input both ports can take before damage--it has nothing to do with the actual S21 output level--you have to measure it as I showed in a recent post

Goodmorning, An answer to your appreciated questions... Ratzlaff - I posted a picture of the edge of my NanoVNA on S11 port, it says "+10 dBM - 10 VDC Max". I think the signal processing levels are

I agree that oscillation is possible, but it should be noted that the amplifier is push-pull, and the 1T coil driving the transistor needs to be in opposite phases. You can view the schematic diagram

I have had an Optivisor and loupe for the past several years.. it has worked well! But.. now the lens in the front pops out now an again and the visor has black push buttons to hold it in.. if you

I used a stereo microscope at work daily for the last 10 years of my electronics career. The B&L were most common, but I used my personal Zeiss scope. The B&L scopes were used with fiber optic halogen

I have two handheld VNAs--a Seesii NanoVNA-H (3 inch screen) and a Zeenko LiteVNA 64 (4 inch screen). Using a SA with VNA set to Start 1 MHz and Stop 1 MHz, the VNA-H S11 output was about -10 dBm; the

What I mean is that the input coupling capacitor may not be the value it's marked with.? In 40 years of repairing electronic equipment I've run into many cases of mismarked, or maybe just floor

The saturated output power of meany of the decent loop amplifiers is >+20dBm, which can easily damage a Spectrum Analyser input. I was always taught to put an external 20dB attenuator on the input to
