Hi folks, I have an HP431C, Marconi 2955a and a homebrew AD8307 meter from a QST design. All read near enough exactly the same for anyone but someone with OCD. The most user friendly is the AD8307

Hi Folks Anyone else having issues with tracking their goodies coming from Hans at the moment? Using 17 Track I'm just getting a number not registered message, this is for two packages, one I received

Jose, Before you do any pictures please check this. Or, at least confirm you have checked. Voltages here will tell if IC10 is faulty. Reiner has said the same. 73 Alan G4ZFQ

Looks sweet. Is this your design, Jack? Is the design freely available? Julian N4JO

Hi Mike QCX+ is available for pre-order now, as are all the accessories and options. The following are currently being prepared and anticipated shipment is mid-June: QCX+ kit

Hi Rob No - have not done any more on key shaping. I was hoping for more feedback from the group as don't fully understand the circuit. I would have thought (wrongly?) that malfunction in Q4/6 would

Alison Thanks for all the info. It will come in handy. Especially appreciate the comment about the reversable USB connector. That relieves my concern about possibly backwards connection. Arv _-_

Allison, except for the bad capacitors incident I have built 4 or 5, 20 meter QCX's and if I follow all the winding turns in the manual, they are consistent with an assembled QCX that was factory

Hi Arv: I guess part of the answer lies with what the final objective is. That is, for most hams using HF gear, measuring down to the micro watt probably isn't necessary. For QRP work, there are a lot

Currently playing with a CHEAP AD8318 board, seems accurate (CLAIMED +/- 1dB) comparing output of my uncalibrated RF generator, 1-8GHz and -65 to 5dBm. I can only test up to 1GHz though. I could add a

Arv, A wonderful instrument to have if your doing any RF measurement. Team it up with a SA and RF measurements get very interesting. Yes, the prices are all over the map as it here are clones like

Jim, what did you do for the USN at Kamiseya, CT perhaps? Spent a lot of 2-2-2-80s at Sabana Seca, PR 1968-1971. Dave, W0DF

George , Differences like that are generally expressed as ratio of powers so 3 w compared to 5W is about -2DB less. or 5W compared to 3W is 2DB more. Now the guy at the other end has his Hilberling

.1 inch happens to be 2.54mm If it were a link it would .com, .info, .biz or maybe down. And no, the Hubble was because the mirror was supported in a gravity well and in microgravity it became a

Rob, I went back to some old notes and see that I did exactly what you have done in turns removal on a couple of QCX20s. 2T off of L1 and L2 and 3 turns off of L3 for a total of L1=14T, L2= 15T and

Would someone comment on the difference between say 3 watts and 5 watts to the receiving station. Are all these measurements masking a trivial gain signal strength. Personally I think the pursuit of

Yes, my bad. I thought the original link was 2.54”. That is how Hubble Telescope mirrors get messed up. :) Cheers, Gregg

2.54mm is the same as 0.1 inches. Roger G3YTN Get BlueMail for Android On 30 May 2020, at 20:00, Gregg Myers <gregg.w7grm@...> wrote:

FYI, you want pin headers spaced at 0.1”. I think the Amazon link was some oddball pitch...
