HT-1A videos uploaded

 

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 !

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,

Re: HT-1A progress update

 

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

Thanks,
Adam

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

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

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?

We already shipped the first 10 kits yesterday and will ship another 10 next Monday. We still accept order at introductory price (125 USD for kit and 150 USD for assembled) by tomorrow (June 30). Please PayPal rongxh@... and leave the message about ship to address. The regular price (+25 USD) will be available on web from July 1.

As it is in massive production now, we will have enough stock after about 10 days.

2P3 IF Transformer ..T2 (Yellow)

 

Hi,

I was missing this part from my kit. Any way to get one ... even if I have to buy it!

Thanks .... Bill


Re: HT-1A progress update

 

Update:
The designer improved fast tuning experience and added a feature to select side tone from 500, 600 and 700 Hz by firmware. A minor fix is also applied to PCB to improve AGC response.

I am going to make the product orderable from my web store on July 1 at regular price 150 USD for kit and 175 USD for assembled radio. Introductory price is still valid this month to save 25 USD each. Please make payment now to my PayPal rongxh@...?and I will ship based on the order time. The first lot will be limited to 20.

Thanks,
Adam
