The 6m oscillator worked just fine. It is another perfect match for the universal direct conversion receiver regarding the amplitude. See:

The next step is a DSB transmitter for 6m.

The cap kit is on the way to the shipping agent. Probably they will arrange international shipment tomorrow.

I have just cleared backlog orders received before June, and I have shipped to all my distributors to refill their stock. The situation is getting better.

Interesting use for NanoVNA!
The price of this measuring device has just increased.
I know there were discussions on the NanoVNA group about its use as a signal generator. Everyone was referring to the rectangular shape of the signal and the problems of using this signal. It's just that no one tested it.
Thank you for sharing this project with us!

The first two shipments were picked by FedEx earlier today. More to come in the coming days. I have prepared enough kits thanks to the dragon boat holiday. I also built a receiver for the hot 6m band. Choc boards are perfect for such applications.

Hello, Everyone and thanks in advance for any help.

I have completed Cricket 20. Using another receiver and transmitter I confirmed that I have local oscillator working, signal being transmitted, and receiver working (receiving signals from the other QRP transmitter). I have no sidetone, however. 

I am wondering where to look. So far I have found several bad solder joints, and switched out the headphones I was using in case the plug was connecting badly to the jack, appearing as a mono rather than stereo headset. Transistor orientation is good.

I would appreciate any suggestions, as I really like operating with sidetone.

Re: Torch brand MLCC

Adam Rong
 

All,

Here comes the kit:

I am asking for about $0.065 each for an assortment of 50 pcs each value (total 50 x 11 = 550 pcs, please allow some tolerance due to the manual counting), plus air priority shipping, total is 42 USD each, and I can accept PayPal to rongxh@... and normally I can ship in a week.

Here is the list:
All are NP0/C0G, 100V, 5% tolerance, 5.08mm lead space, light green, TORCH brand
5.1p, 10p, 22p, 33p, 47p, 82p, 100p, 220p, 330p, 470p, 820pF

See the initial test report for my last batch by K7QO:

Hi Ken,

A few years ago, I kitted an assortment of Torch monolithic NP0/C0G capacitors and introduced in qrp-tech group hosted by K7QO. They were very low priced compared to other world famous brands, but they are very stable and high quality. Torch is the top brand in China and my kits use them a lot. Yes, they are the green "beans".

I think I can still continue this business after this surge of COVID-19 here. However, the price soared these years.

Re: Mouser Finally Shipped My FT37-43

I just received the toroids ordered last December and shipped by FedEx early April.

Jim,

Thanks for the information. I can purchase from DigiKey too, but I just encountered such a long time of shortage from Mouser.

FairRite does not produce T series toroids. Micrometals does. Amidon is not a toroid manufacturer, neither is kitsandparts.com.

BTW, kitsandparts.com was one of my suppliers before, but I am very surprised to see their political decision.

Digikey shows 152,0000 of the FairRite 5943000201 in stock as their stock number:
1934-1386-ND

https://www.digikey.com/products/en?keywords=
1934-1386-ND

That is the FT37-43 or so I have been told.  I have not found cross reference FairRite numbers to micrometals toroid numbers (T37-2, T37-6, T50-2,T50-6, etc) but would like to find that information.  I find several cross reference charts but none include toroids but do include the ferrite toroids (FT##-##) like the FT37-43.

I don't know if Digikey is one you can buy from without high shipping costs but they do have them,  at least here in the USA.

Thank you.

All,

I ordered the Fair-Rite FT37-43 toroids from Mouser USA last December, and the shipping date was pushed out and out, and finally they shipped a few days ago, after more than 3 months!

The Fair-Rite toroids are made in China. I talked to the local sales manager and I was told their lead time is up to a few months.

Due to COVID-19 surge in China, I suppose the supply will be even tighter and the price cannot hold. Let's cherish what we have now.

Stay safe and have fun!

Thanks,

Adam

Thanks guys. Things are getting better.

I keep using Choc boards for my experiments and prototyping. I recently found an article about it in Japanese which you can read by auto translation. It looks interesting.

I have attached a few documents and videos:

This is one unit of the board and you can get a free version of the design which you can make your own board (it is 2x3 units) if you are interested. Let me know if you need the file.

Thanks,

Adam

All,

The situation is getting better and I went to the street for the first time after lock down. However, I still cannot go to my workplace, and the shipping is still not possible. I guess it takes up to a month to get everything back to normal. Stay tuned and thanks for your attention.

Thanks,
