- Building and testing the Kanga Products FOXX-3 transceiver. This kit is great for beginners and has features few simple crystal controlled radios offer, like a sidetone and the ability to change frequency a little. One Watt is really not an obstacle, as you will see from the reports. Good as a survival radio? Not quite, but it is fun and beats nothing any day. www.kanga-prod... (tell Dennis I sent you!)

I've enjoyed building many of the QRPme.com kits and this reminds me why I got my Novice ticket in 1979. Thanks for sharing!
I think I will try this as my first kit build
I am recommending to choose RockMite ...better performance and more features with similar simplicity. Check W1REX site.
I might try this as my first ham kit in over 30 years.
Thanks! And I enjoy watching your videos
Thanks!
Very nice video Gil, it’s always rewarding to build these little kits. The RBN results are definitely amazing and it is a nice little transceiver to carry on vacation... Maybe with a kite antenna ... and this would definitely be much more fun than TV !!! 73 Serge
Thanks.
Hi Gil, I to bought one of these some time ago they are a great little kit to build and operate in the field, one thing you should always do when building the kits is check the torords for inductance, it does make a big differance, when all of those cheap chineese kits hit the market years ago i bought two of them, pixie, frog sounds, forty 9er etc etc, the first one no checks made but they worked, the second attempt, inductance, voltages, capacitance, resistance, and some of the values checked and replaced were needed, it made a very big differance, buying components with half decent values percentage today is getting more difficult, enjoyed the video as always, have you solved the prolem from your last build
Goid advice thanks. I don't have an inductance meter though.
@@RadioPrepper you can get them on banggood they are called secometers
You are doing ham radio like I dreamed of doing when I was a teenager, make your own radios and feeling that accomplishment of making something that works and is useful. 73's KD9OAM
It's never too late... :-)
My new favourite channel. Thanks
Working
Thanks. I only watch series and movies on the Internet now...
Another great vid Gil, I’m waiting for my first kit to arrive from QRPGuys the EFHW mini tuner 40m - 15m that should be fun!
When you mentioned the altoids tin was its own faraday cage, it reminded me of an interesting article on Offgridham entitled - EMP Protection For The Radio Amateur. An interesting read!- “ Better than Television”👍🏼73
Do you have a link?
Hi Gil, yes. Offgridham/2017/11/emp
Your thoughts would be interesting 73
Hi Gil, builted one about 15 years ago to replace my HW7 on holidays, the transmitter section is good but the receiver makes the HW7 sound like a Icom 7300!. Nice kit to built but not usable, it was deaf and had AM break through, I binned it and bought a TenTec 1320 and still use it on holidays to this day, I love your channel and check it every day, thanks Gil. 73 de gi0ggy.
Thanks, interesting.
The YT Algorithm has offered this 1 year-old video, how nice! I have the FOXX-3 since more than 5 years now and it was an interesting challenge to get a qso on it. And I've made it! The first was with the HB9 station some almost 2000 km away! The guy was surprised I was running 1W, so was I :). I have made some more contacts with it using my permanent full-size 80-10 EFHW antenna. The biggest drawback of this type of radios is not the 1W really, it's the non-variable crystal oscillator... It would be fun to come back to this project and improve it with adding one of these now largely available one-chip synthesisers. Might be a winter project! 72! Linas LY2H
Great, how is reception on yours?
@@RadioPrepper Have not been listening to it since few years, but when I switched it on now it was like a bit of overloading from the big antenna with the SW broadcast stations whom I could hear quite well :). I'm really getting curious to look into it again! Thanks for bringing it back from the junk-box!
Maybe I should try it again...
Had a look at the schematic, it looks like FOXX3 uses the Pixie scheme where the transmitter PA doubles as the receiver mixer. Actually the design is originally from George GM3OXX in SPRAT 1983. Hence the only receive selectivity is provided by the LPF, so it is open from the crystal frequency to DC. Will be prone to AM broadcast interference. Surprised you don't hear more band noise, you may have heard more with a 40m kit. A novelty, not really useable, and the 1 watt is not enough to be fairly sure you'll make a contact. Still, a bit of fun! 73 Paul VK3HN
Love it, very cool.
If you're hearing music then there must not be a narrow filter in the radio circuit. Interesting little "toy" to build. At least it provides good soldiering and toroid winding practice! Nice video. Informative & entertaining. Thanks de Jim, AE5ZX
Thanks. None of those cheap transceivers have any filtering..
@4:21 you can buy small metal clamp-on ' Heat Sinks' to use on components while soldering - - so the heat is pulled away from the component and it won't Burn-Up !
Definitely!
I built this toy almost 20yrs ago, hihi. Longest QSO was EU to ZL with 250mW from Foxx! Nice...but not proof against BC breakthru! I am recommending to use additional BPF...
Or a mag loop antenna!
@@RadioPrepper yes as it is high-Q resonant circuit which can filtering the BC sigs. Agree mate. Good luck...and stay safe.
You too!
Relaxing in the Nature is still the best Movie.
Sure is!
Very interesting!
Thank you.
Kit's are addicting
Hello, thank you for sharing, maybe it would have been great for me in french, i did not understand every thing. I like your very instructive videos. Have a nice day from FRANCE
Merci! Désolé d'avoir manqué votre petit bonjour sur le livestream 😀
Hi,Good video.I have just built a 40 meter unit. Great fun but I too have low receive audio. It transmits 1 watt.I have found out that the LM386 op amp used in in the audio amplifier circuit comes in different amplification values. I was supplied with a low rated amplification version,( LM386L rated at 0.325W ).For instance amplification of the "N" range of LMs is as follows:- LM386N-1 =0.325 watts ,the -2 =0.7 watts and the -4 =1 watt.I will try a higher rated LM386 to try to boost my audio level.Hope it works.Dave
Hi Again,I was tired when I wrote this !! I should have said different amplification and power outputs. The chips are so cheap anything is worth a try to boost the audio output.Dave
Gil, you might want to look into Diz's 5Watter kit. It's an update of his and K7QO's 1Watter kit - now sold out. It will have a VXO/VFO, keyer, and decent audo and sensitivity, etc. The footprint is somewhat larger than an Altoids box but can be housed in a small case. Check it out. Should be available in July 2019. Google Kits and Parts 5Watter. No pecuniary interest, just liked the 1Watter.

Thanks. Aren't they closing shop though?
War Planner, can you post a link to the radio you are talking about, please.
Thank u for quick response .
Opss i thought the Box included ..
i loved FOXX-3 and i think it has a better quality components and design VS Pixie , but 41 US dollar ... and No IF Crystal Filter .. No Box included ... i think it's a little pricey
It is better than a Pixie but not as good as the SW40. The QCX from QRP-LABS is the best one for $50.
Hi there, you can replace the PA transistor with a beefier one. If it is NPN the maybe a BD139?
Not sure a beefier one would be more sensitive in reception but there m8ght be better choices indeed..
Pas disponible en 40 mètres chez kanga-products... J'ai découvert votre chaîne en regardant la vidéo que vous avait fait en français, je m'abonne, cordialement Gaël - F4IHG
As always, an excellent video. Question; have you tried a high impedance amplifier for your sound? I use a modified telephone conference type amplifier or a small guitar amp for items like this or for listening to crystal radios, rather than a regular sound amplifier based on the LM386 chip for amplifying a radios sound output . The sound level is much improved.
I used that little amplified speaker which usually works great with other qrp radios.
Just got a 30M one. Neat.
Please let me know if you find it sensitive enough..?
Radio Prepper ok. What tuner were you using in this video?
I ordered a 40m and a 20m but the online shop had no way of telling Dennis that you sent me.
Cool, no big deal :-)
Thank U for Step By Step with high Quality video/Sound demonstration ..
Yes there is interference with an Arabian Broadcast ... I don't know how such Broadcast emit the wave close to Amateur Band ..
However , i am still eager to explore the (Selectivity of this Kit) VS (SW-40 Transceiver Kit) as both have the same Price Rang and Size ... and How does the Cheap/Small Pixie would compete ?
By the way ... is the "ALTOIDS" box included with the kit ?
The SW40 is much better. You have to buy the mints yourself! :-)
Nice video and thank you. What is the best kit you have bit that fits in a this can!
The Weber MTR! Check out The Rockmite too, from QRPme.
On the face of it, it looks pretty simple, but everything i build tends to break lol - I prefer the pre-made kits.....
Good little kit though. The size is great..... It would be good to have a number of stations out there with the same pre-made radio all Txiing.... Wonder if anyone has any great 'ranges' from this?
I was heard in Russia!
Great video from you as always, but how did you know how far away you were heard? The screen came up with UD4FD at bottom.
Hi, I checked on the Reverse Beacon Network site..
@@RadioPrepper Thank you. I didn't know about this so will check it out. 73, GM0JDB
Sorry if I missed it in the video but what is the range between transmitter and receiver
It can vary greatly between a few miles to a few thousand miles.. Usually around a thousand. It depends on solar activity, ionisation of the ionosphere.
@@RadioPrepper thanks for getting back! This was very helpful!
BC212 is PNP while BC237 is NPN. That can't of course work. Any PNP would work fine.
I tried another PNP, didn't work, so I asked for a replacement..
Have you thought of trying a ceramic resonator in place of the xtal?
I would for a homebrew project...
What are you using for a tuner for that antenna? And where are you located that you are able to pick up the radio prayer time?
No tuner. South of France.
Radio Prepper yes, sorry. I missed the vertical antenna part. I was thinking you were using a long wire.
Frizzante 4 whiskey beer yukonjack ;)
Can i ask a favor?
You can always ask...
@@RadioPrepper can i have the music of your intro that morse sound i want to make a ringtone to my phone thanks.
I don't have the file anymore but give me a word or two and I'll make you one. Send me you email at gil@radiopreppers.com
GIL ?
Yes...?
Yes...?
Only CW. That is a show stopper for me. I prefer phone.
It's all about size...
@@RadioPrepper True but an Elecraft KX3 is just a tad bigger and will do it all. That being said, I traded my KX3 away after owning it about a year. It just was not for me. Glad you are enjoying the CW though!
Drew Paschal its also about 40x the cost and cw will get thru where phone wont
It's a personal preference of course, but you're not going to get anything like the simplicity, range, and cost-effectiveness with phone. A comparable kit for SSB would be at least 3X more expensive and about that much less fun. Like I say, it just depends what you like to do.
@@drewpaschal9294 kx3 vs $25.....ha ha ha ha ha ha ha!!!!!!!! You definitely get more bang for the buck with the foxx3
