Building of an forty-9er kit

[@d3w4yn3]

This is an encouraging video. I just received my kit, but I have not built it yet, but now you have given me good motivation to start!!!

I used the PA circuit to build a QRP beacon and found the device sometimes died. I was observing some unwanted oscillation in the PA. Fixing a 30V zenner from collector to ground fixed the problem. 73

It seems like a good solution for not spending much. Were you able to make QSOs?

[@echopapaqrp8166]

No, I was not able to make a QSO. You need a much more powerful antenna than mine. But I think it is possible.

@@echopapaqrp8166how much power did you get out of it ??

[@echopapaqrp8166]

@@MidlifeRenaissanceMan Iam not sure. But I think something about 1-2Watts. But never the announced 3Watts.

@@echopapaqrp8166 my mate George VK2AOE, who has the Art of Engineering channel just built one and the finals lasted 15 minutes before they popped I was curious as to how yours held together Did you ever manage to get a QSO since making the video ?? Thanks for getting back to me de VK2NAP

[@dusanmirkovic3544]

Good video. Thank you. Can I use this device to practice typing on a lambric key?

[@HALEdigitalARTS]

Very well done video. Thanks!

[@stevewheatstone1856]

Where did you get yours from? I only seem to see bare pcb kits, none with the case..73

[@echopapaqrp8166]

I ordered at ebay. It seems to be changed very often.

[@stevewheatstone1856]

@@echopapaqrp8166 thanks, I will look again. Just got a SW-3b too but issue with screen and waiting for replacement. 73

[@gliderrider]

Thanks for the video! I always worry about Chinese kits quality. Did you use eBay? Who was the seller?

[@havefun2952]

Hi, I am a new ham. How many AA batteries are in your battery pack? What is the name of the wire which connects the battery pack to your transceiver?

[@tonywright8294]

If you need to ask don’t bother

[@PatrickZPope]

How many turns on the toroids?

[@PatrickZPope]

On the 49er.

[@PatrickZPope]

How many turns on the toroids on the 49er?

[@echopapaqrp8166]

I don't know anymore. It was described in the small manual shipped with the kid.

[@macgyver5108]

This "forty-9er" kit doesn't look at all like any forty-9er kit I've ever seen, all the components are WAY spread out on this PCB not at all compact like the typical kits, the PCB is green too instead of red and it also has a 3rd torroid vs only two?! With that cleared up, not sure if what the original kit uses will help but here goes... L3 is a FT37-43 and gets 11 turns of 0.51mm wire. (thicker torroid, sometimes it's green) L4 is a T73-2 and gets 16 turns of 0.51mm wire. (thinner torroid, red)

[@prestonshute7243]

Very nice build and video. 73 wd4dda

[@echopapaqrp8166]

thanx 😃

[@G7VFY]

Are you going to try replacing the 7.023MHz xtal with something more QRP friendly? G7VFY

[@echopapaqrp8166]

I think about this. But on 7.023 is a lot of activity too. This could be a seperate video... Vy73/72 DL2NEP

[@RobMacKendrick]

@@echopapaqrp8166 You could also incorporate a Pixie switch and have your choice of 4 different frequencies -- including the Chinese QRP freq that came with the kit -- whenever you want them. Thanks for the informative video!

[@adistef]

I was under the impression that you should not TX without an antenna; maybe use a dummy load if you just do some tests?

[@wkjagt]

If you look at around 3:03, I think that's a dummy load he removes from the antenna connector before connecting the antenna.

[@adistef]

@@wkjagt true! at a glance, to me, it looked like an adapter for the antenna connector, but yeah, my bad

[@WFSteury]

My 49er is also better than my Pixie. I recommend it. The receiver is excellent and the output is about 1 W. N9EGT

[@РоманС-ш5щ]

Привет. Получил с Алиэкспресс такой же набор. Стал смотреть, а там вместо микросхемы NE602, продавец положил другую. NE592D. Я не знаю, наверно это не аналог NE602.
