Re: 2020 new year announcement
Folks,
During Chinese New Year from Jan 21 to Jan 30, I am not able to arrange shipment. If you wish to place big order for R3500D ARDF receivers, you will need to wait until early Feb.
Thanks,
Adam

Re: 2020 new year announcement
Hi, Adam!
Happy New Year! And Happy 9th Anniversary of CRKits.com!
These are very good news! I was thinking to order
D4D DSB Transceiver Kit and Mini Wire Antenna Kit for a some time and now with the drop of the prices I will do it! Also I am interested in getting?
KN-Q7A or CS-series PCBs that you'll offer. I am interested in 20 and 40 m variants. I would like to ask you whether you may send these PCBs together with D4D Kit and Mini Wire Antenna Kit?
I think you are doing a great job for Radio Amateurs and your products are very interesting. When I first entered your web site I was surprised that some of the kits are sold out - especially KN-Q7A, CS-series and Choc Perf Boards. Now with your offer I would have the chance to build one of these kits.
I am a Bulgarian ham, but I live in Albania. I hope you can ship to Albania? I can pay through PayPal.

Folks,
Happy new year!
2020 is the 9th year of CRKits.COM and I am glad I am still active with this side business, although I travel 95% for my professional work.
In 2020, my US distributor Larry will close his web site and only support local customers via his facebook page. I have decided to revisit my pricing strategy and would cut about 10% for all my offerings. Please visit my web store to take a look.
As a gift to my customers, I would offer free main PCB of KN-Q7A or CS-series if you still remember. Please follow this thread if you need one or two piece. Please PayPal 5 USD for the postage. You can also request key parts to ship along if I still have them.

Re: 2020 new year announcement
Hello Adam
Happy New Year!
Well all the Holiday gifts are hanging in the closet, I would like to order the 40 meter CrKit for FT8 operation.
Where do I specify that I would like it “assembled” I know you said there is an extra charge. I plan on using PayPal?
Thanks

Re: Replacing BD139 with 2SC1969 or equivalent RF Transistor
Hi Nick,
The biasing would need a little alteration but it should work fine as is. It also depends of course on what tcvr you are altering. What will get the most gain is isolating the finals from their original supply voltage and increasing that from say 12v to 24v. Since you are on this forum I expect you are using CRkit products. The spectral output is not great on these products, but they're built to a price point and simplicity.
If you really want to do a good job, dump the original finals and build a daughter board using your silicons.
It's really a chore of diminishing returns, those transistors are expensive compared to the BD139 and although you can push your output a little higher, 12w as I remember, there are cheaper easier options.
Try look for a design you can build outboard, maybe with a push pull circuit or doubled up finals.
Good luck, Nigel de ZL1NAY
Hi
Has anyone experimented with replacing the BD139 output transistor with a 2SC1969 or other transistor to increase the power output? It seems technically possible...
Thanks

Re: Replacing BD139 with 2SC1969 or equivalent RF Transistor
You would need a lot more drive to get any significant power out of the 2SC1969, which means adding at least one more stage. It would be easier to drive the 2SC1969 with the existing BD139. All in all, not work the effort. ? Steve KD1JV ? Hi

I was intrigued by that bug as well. A little searching opened up a whole world of Keys made from binder clips. Start with this .

Re: New Enhanced Pixie Kit
that is one cute little rig.
my only trivial suggestion would be to use a phono socket as a cheap/cheerful/robust antenna connector to avoid the cost/fragility of the sma socket (and sma/bnc adaptor we need too... the leverage on them makes it all to easy to wrench the main socket out
of the board whereas a sharp pull on the coax simply disconnects a phono without damage)
