Re: HT-1A introductory price ends tomorrow

Adam Rong
 

Now you can order via web store http://crkits.com by adding to cart.

I have fulfilled all direct orders. Our distributors in Japan and USA should receive some in a few days. We are looking for a distributor in EU for HT-1A.

Thanks,
Adam

HT-1A kit building instructions and new videos

Gang,

HT-1A kit building instructions updated to Rev B in here.

Re: CS-40F: Radio for FT-8

Jim
 

Will the finished version FT8 radio have build in VOX circuit & USB port? Those two things would really help this rig sell.

I think it should have 3.5mm audio in/out ports also.

Will it have a small frequency display for fine tuning?

Jim,

I ran my test based on a USB to TTL converter board. At this moment, I don’t have plan to offer a VOX circuit as the converter will do PTT control quite well.

Thanks,
Adam

Re: HT-1A progress update

Adam Rong
 

Gang,

The first batch will be depleted soon and we are waiting for the 2nd batch because the case customization might take a few weeks. So far the feedback is quite positive and we are waiting for the first eham.net review soon.

Most kits went to Japan. As the Tokyo ham fair is coming soon, please check out the sample at the QRP village booth if you are visiting Japan. It becomes a tradition thanks to Nakajima-san that CRKits products are shown in the QRP village booth every year.

Recently I purchased a few old Kenwood radios like TS-940S and I am amazed by the great performance and nice design about 30 years old. The documents are well written so I can easily repair my radio if it goes wrong. Good examples for me to follow.

Thanks,
Adam

Year end big promotions

Adam Rong
 

Gang,

This is the 7th year of my kit business. Starting from October 1 (shipping date) till the end of this year, I will offer discount as follows:

1. All products on http://crkits.com will be free shipping to worldwide.
2. If you buy the second pcs of a product, you get 10% off. So invite your friend to buy along so both of you can get 5% off.
3. You can place orders now to qualify the above discount if you accept shipping later than Oct 1.

Thanks,
Adam

Choc Perf Board article published

Adam Rong
 

Gang,

My article “Make a SSB transceiver with the Choc Perf Board” was recently published by the Sept - Oct issue of Amateur Radio magazine from Wireless Institute of Australia. 

To see the table of contents, please go to:

To view the article, you can download from my web site:

If you want to try out the boards, you can PayPal 10 USD to rongxh@... and I will ship 4 pcs (2.5 x 4, free shipping) during the promotion period of this year end.

Thanks,
Adam

HT-1A videos uploaded

mx6s@...
 

Hi All,

Followings are my HT-1A field operation video in California.
On the day, 40m condx was not good. So I moved up 20m and made several QSOs.
This 5-watt dual bander worked fine in my travel. Equipped internal battery, 5W continuous output,
good sensitivity and easy to see display are the nice companion's feature during trip.
Enjoy !

Still remember KN-Q7A?

Adam Rong
 

Gang,

I listen a lot but seldom transmit. Although I have a few radios to choose from, I still wish to build a dedicated receiver. I hope it is low noise and high performance, so I consider KN-Q7A receiver portion. By using four crystals in crystal socket, I can tune 7.000-7.030 for CW, 7.050-7.130 for SSB. I added a power switch and power indicator LED and power consumption is about 35 mA.

I have depleted MC1350 so I believe for a while it is not possible to produce more CS kits, but I have an alternative solution and it works fine. Some redesign is required, so let’s wait for some time. 
Thanks,
Adam

Re: Still remember KN-Q7A?

 

Adam,
I have the very early one and it is only 10-KC TX.
Can the early unit receive the CW part?
What is the resistor on the jumper for?
Thank you
BOB AF2DX

Bob,

To receive 7.000-7.030, I used VXO crystal of 15.500 MHz (this is the one used with 8.192 MHz IF to cover 7.280-7.300 MHz), and the IF crystals are 8.4672 MHz.

The resistor on the jumper is the current limiting resistor for the amber LED. It can be 1~3.3k ohm.

Thanks,
Adam

Nakajima-san,

Thanks for sharing these videos during your trip to California. Dual bands, more chances to make QSO. 5 watt is also very important for some poor conditions.

Thanks,
Adam

Adam,
I have heard nothing except band noise on my KN-Q7A from 7.050-7.130 since mid November 2017, but very occasionally further up the band on my main transceiver and antenna. Bottom of cycle has really hit this area Newfoundland. 20 mtrs is dead.

Re: Still remember KN-Q7A?

 

Hi Adam,
Thanks so much for responding.
I will check my crystals so I can use the rig to copy CW.

Re: Still remember KN-Q7A?

Hi Adam. The KN-Q7A is a very good rig indeed, no doubt about that. If you are designing a receiver from scratch on 40m, then 7.000 through to 7.150 at least is a must, because Parks on the Air, SOTA, and other portable operations use 7.140 through to .150. And - AND, then there is the CW qrp operations at the lower end of the band. The LED tuning is ok, and gets around a problem, but a small LCD display smaller that the usual 16x2 would be a real advantage.
Just my thoughts. Keep up the good work

Re: HT-1A videos uploaded

Timothy Fidler
 

It would be really nice to have a video from an English speaking country,,,, I include America there, showing how the HT1A performs in SSB listening mode. Some CW tcvrs are find for this but others like the one from Hans Summers simply cannot do it because of the architecture.  FW it is worth. ..there must be something on Ytube but mostly it is older models...
