Greg,

I have built a test sample of CS-15V. The coverage is 21.248-21.268, and power output is 3 watt PEP. The spurious is about -40dBc. The audio is nice to hear.

I can accept order now for CS-40V and CS-15V. Same price 60 USD for kit and 15 USD for speaker microphone. Express shipping is 20 USD. I will ship next Monday. PayPal to rongxh@...

Thanks,
Adam

Hi Adam,

sounds interesting. I'd love to play with the kit!

Jim,

Thanks for asking. You can drop me an email or directly PayPal and leave a message to rongxh@...

BTW, the IF for USA is 8.192 MHz instead of 8.467 MHz.

Thanks,
Adam

Folks,

CS-40V kits will be shipped in 2 weeks. Here, V is for VXOrganic. There is no DDS, MCU, or anything else digital. All analog, all organic.

The IF is 8.467MHz and I have improved the pass band flatness with a better impedance matching. Thus, the audio receiving and transmitting sounds noticeably better. Fidelity is sort of organic.

The IF amplifier chip MC1350P is gone. The replacement is also an organic solution, a tiny module of a dual gate FET. If you still have MC1350P in your stock, use it. If not, you can use this replacement solution. The gain is lower, the gain control is counterclockwise, but it is quieter. Using what you have is also sort of organic.

Again, I will do the kitting all by myself, the owner of the business. I can memorize all the parts. No low level mistakes by rookies. That’s another sort of organic.

The packaging is a bubble envelop. The printed manual is removed. You don’t have to worry about the trash disposal. That’s another sort of organic.

Finally, the price is 60 USD. That’s not usual price for organic, but lower price will reach more customers. The price for microphone speaker is 15 USD and the shipping is 20 USD or 5 USD for returning customers.

Yes, you can place order now offline.

Thanks,
Adam

Greg,

Although sunspot is still low, we will see increase day by day. I have parts for 15m version. I can foresee the power output should be lower but I will give it a try when I have chance. If you can test together with me, let me know so I can provide parts at discount price. The frequency is around 21.230-21.260MHz.?

Thanks,
Adam

Guys,

I have just completed the prototype build of the first CS-40V and it is a big success! I did modify the crystal filter response and it is much improved. You can view the photos from:

For how you order, please stay tuned as I will start another week of busy work. I should have better idea next weekend. During this week, I can order parts to prepare.

Thanks,
Adam

Folks,

The new batch KN-Q7A will be named CS-xxV. Here, CS means I will use CS-series face plates, xx means meter band, such as 40, V means VXO version. If you wish to order 40m version, you can call it CS-40V.?

The difference between KN-Q7A and CS-xxV:
  • CS-xxV uses the main PCB and face plates of CS-series
  • CS-xxV has a LED for TX indication
  • CS-xxV uses both B10K potentiometers
  • CS-xxV uses MC1350P replacement solution
  • Perhaps CS-xxV will have a modified crystal filter design

Folks,

A week ago, I checked my inventory and found some parts for a few CRK-10A CW transceiver kits. One of my friend in China built a kit and was impressed by the good performance and smooth QSK. And this morning, I just realized that I have replacement solution for MC1350P so I can bring up the much loved KN-Q7A SSB transceiver kit. The initial testing was promising although the IF Gain is not as big as MC1350P.

I don’t know how long I can stay at home before my long time business trip, but I think I can do something to prepare. The old kits will be priced at more affordable point. Let me know if you like the idea. You can check out the manuals at ?to know more about CRK-10A and KN-Q7A kits.

Folks,

I have registered my ex-callsign BG6CR when I was in university, but for some reason, I cannot register my current callsign BD6CR. With the kind help from BD4AAQ, now I have the full control of the registration. You can check out my biography if you search BD6CR at

Re: Bring back some old kits?

 

Sure. I have parts for about total 20 kits. It seems they will be gone in no time.

You can purchase from either your country or China. I will ship a few kits to Larry shortly.
