Good point …. Gotta try for kiwi land 🐑🐏🐑🐏🐑🐏🐑🐏

Sorry to hear he is SK. Yes the inductor has been fine. My rig has had things “done to it”’(CB and QRO MODS not by me). Just glad to have it going so TNKS for the comment and a posthumous tu to Ken for his site too 73.

Hi …. Yes lotsa fun! Here is a link to my other video. You don’t have to watch it just read the video description! Used to be just 80m TUESDAY evenings 0900UTC to as late as 1400z. So this description doesn’t tell u new 40m net, which is very popular! 0700 - 0900z 40m 7.025 - 7040 k 0900 - 1100z 40m freq as above 80m 3.540 -3.570 k 0900 - 1300z 80m freq as above Also email Mark Bosms and get on the email rag chew newsletter (all part of the fun!!) mark.bosma@icloud.com 73 and thanks for popping by! ruclips.net/video/cKUpTPViK94/видео.htmlsi=zzHF9oIog89KGLPW

Thanks for the comment. At some point in time would love to get my hands on a Yaesu FT101 too! 73

Ha ha…. watch this space ! 😝 73

I just masked off the Gyprock wall and used blackboard paint. Fun place to noodle ideas! 73 de VK2AOE

@@TheArtofEngineeringThanks sir

Thank you....I normally calibrate whenever I change the range of "stimulus". I must of not done it in this case. Thanks for that tid bit of useful information that I didn't know! Just tried it and 100% correct. Nice to know as it will remind me to do it! 73 and TU OM most useful.

I think it is black paint :)

For me ...perhaps the only way!!! :)

I buy a lot of of stuff on Ali Express. The component quality is often hit and miss though....all part of the fun I guess? 🤣🤣 Thanks for popping by! 73 de VK2AOE

Yes! It snapped together in such a satisfying way. Totally agree the solid weight in the palm of your hand and performance makes it amazing value. This is why I will be shopping again tonight before the “good thing” comes to an end! 😜 73 and thanks for popping by. De VK2AOE

I did stand them up in the end. My latest build is even more of a disaster... but will operate on it soon. It still has got me to Victoria though but chirpy :) The QRP LABS QCX mini is a ripper! 73 de VK2AOE ruclips.net/video/M7MuVNmIXb8/видео.htmlsi=YdPLJzxRIQrjBR_W

I am by no means an expert. Obviously be very careful as the voltages are deadly!! Only proceed if safe and you know what’s going on. Have you tried with driver tube removed and heater switch on…. To see if that kills receive? It is an interesting fault? Let me know what caused it, when the solution is found? I will keep my ear to the ground and if I hear anything helpful will pass it on 73 de VK2AOE

​@@TheArtofEngineering First of all, I can't be more grateful for your quick response. This equipment has just arrived in my hands because I really like valve equipment. They seem like engineering jewels to me. I have carried out the test that you propose, If I remove the Driver valve, 12BYA and right after I activate the heater. The reception is perfect, it is not lost. Thanks again

Apparently it could seem like a valve problem. I don't rule it out. What happens is that I have tried a second valve and the problem persists. Unfortunately I don't have a valve tester to know what condition these two valves are in.

Yes…. Twas very helpful for the build. Tnx fer the comment 73 de VK2AOE

Thanks .....It is a bit of a mish mash and a bit deaf...but I have worked some QSO's in OZ and has been a lot of fun! Thanks for the comment 73 de VK2AOE George

muchas gracias!!

100 % agree! Been a great unit. 73 and thanks for dropping by de VK2AOE

Yes …. But I removed the 50 ohm resistor to earth at input and the pot. So mine was a fixed bandwidth (narrowish but I didn’t measure it?). So 4:12 is the cct as provided by the original creator. I found the bit I removed were causing too much attenuation for my preamp. 73 de VK2AOE.

@@TheArtofEngineering thanks

It narrows the audio frequency passband… so it is a poor man’s substitute for narrow IF type filters. 73 and tnx fer the comment.

Thanks! Was it a synthesised VFO, Xtal or VXO? Transceiver or xmitter? Love homebrewing. 73 de VK2AOE

I used a 74HC240 and a crystal and irf510 I am currently working on a jfet vfo for it. It's a good little oscillator and could even be driven by a DDS etc. hope to catch you on CW soon 😁

😆🤣🤣 All my CW QSO's are a battle!

Thanks for the comment. Twas a great life and best job at sea. CW is in a real Renaissance here in Oz. The QRS net is growing weekly and lots of interest in code! 73 de VK2AOE

My friend ….Mr AI wrote it for me ! 😜😝😝

Yes …. I send more smoke signals than RF! 😝 The static sensitive stuff has gotten better over the years. I worked for a data com company and the chief engineer used to belt me when I didn’t plug in my anti static lead… the chips were $$$$$ back then.

Thanks Peter. I saw your video for the “toy” 40m rig. Makes a huge amount of sense to dodge that possible nearby opposite “image” freq for a DC rig. … especially if the band is busy. I have a matched variable… might give it a crack! Thanks and 73 OM

You tease me with these tidbits! Yes please . I am like Charlies mentally deranged progeny....baaaaaaaaa

@@TheArtofEngineering I have all these parts and no time to do anything with them. My X Phase QRM box is still in bits whilst I try to get it to react to the PTT control at the back of the FT747GX that goes from 12V 0v when you key the mic. 0.6V when you press the MOX and 1.2V when you key up on CW. The P channel MOSFETs are still in their bag next to the little SMD variac diodes. No through hole ones I’m afraid. How’s the DTs ?? Beer steadies the hands

I tried to send my CALLSIGN and QRZ? After each K …. But no reply!!!! 🥹

Yes …. Correct. But I’m an AMATEUR radio operator not an RF engineer. So it is Digital Synthesis (as the RF is produced by digital means) but NOT DIRECT Digital Synthesis. It is my understanding that DDS only allows a change of frequency if the reference clock is changed …. So this might be why amateur projects don’t use it (too complex?). Why would you use a true DDS for a simple CW transceiver if a PLL derived signal suffices? By the way no offence taken, this type of comment is how we all learn about this hobby we ALL love together: if you do find a DDS (or design one) drop me a line. 73 de VK2AOE

@@TheArtofEngineering "..but I'm an AMATEUR radio operator not an RF engineer.." running a RUclips channel labelled "The Art of Engineering" ? whatever, its only RUclips. Your description of DDS is totally wrong, Google will sort you out there. There are a number of REAL DDS VFO and sig gens kits and projects already out there, created by amateurs, most seem to use the AD9850 chip, and no they are not really anymore complicated than this circuit. 73 de G0AFV

@@bazzaar1869 I have a Radiocommunications Engineering Certificate… Fine Art Degree and I’m part way through (18 months) of a Mechatronics Degree. Hence the channel title. As for RUclips “sorting me out” …. I do this for enjoyment…. But the channel does grow up to 100 subs per month, so some hams are enjoying the content. 73 OM.

It is probably best to describe lift using one or the other. I think for the NSW HSC either is OK. I suspect both have a part to play. Newton's flow turning explanation and Bernoulli explanation. see link below 😜 www.grc.nasa.gov/www/k-12/VirtualAero/BottleRocket/airplane/wrong1.html#:~:text=Therefore%2C%20the%20molecules%20going%20over,the%20airfoil%20produces%20the%20lift.

Thanks Peter. I love spending time looking for possible ham uses of things I come across…. I’ve built a CW key from BUNNINGS bits and found numerous cases in Hot Dollar stores too. 73 de VK2AOE

Before I my wife throws anything away I have to vet it to see if it could be any future use in the ham or engineering world. Not much ends up in the bin. 😃 G1UOD.

Thanks for the feedback Peter. I do overdo them sometimes. 73 de VK2AOE.

Yes.....2 primary windings in series. Video 2 in the series shows the current clamp primary current value for one transformer (1.7 amps) and then 2 transformers in series less than 300mA. The supply is now my main shack supply and is still going strong! 73 thanks for the comment de VK2AOE.

I have the Sprat handbook from GQRP AWESOME read too!

Yes I love RUclips for this very reason. We get to see how stuff happens! 73 and thanks for the comment.

Sorry not sure about that? I bought the switch as I’m going to build a receive only loop to use with my Airspy SDR receiver. 73 de VK2AOE

Alas the museum is largely bereft of knobs? They did have a Morse display that sent a message…. Badly!!!

Oh no. That’s so sad. German straight keys are much loved by the lucky few that own them. Managed to work 3 states on 40m in the car whilst driving to and from the gong the last couple of days. Left handed sending and only head copy. Because Morse isn’t hard enough already Did you take a mini rig with you ??

Test works… 🍺
