Hi Adam

 

DSB Tx works perfect!
My first QSO with 1 Watt was HB to Spain (EA) abt 1700km!
Very surprising also with the actual condx.

 

73s Beat/HB9CRE

Bob,

 

It is less than one watt DSB mode for 20m band.

Thanks,

Adam

Folks,

 

Still remember the quarterly contest? Last time the 1st place was BG7IKK. He made a QSO from Guangzhou China to Italy with distance over 9000km. Today he refreshed by a QSO with W4UAT with distance of 11233km. He got report of -19dB!

 

His rig is our D4D 20m and the antenna is an EFHW.

 

You still have chance to win the contest before the deadline of the end of September. Show us your QSO!

 

Thanks,

Adam

Folks,

Thanks for letting me know. I had thought you guys all haven't had chance to take a look at the kit yet :-D

Thanks,

Nice guys, thank you!

Folks,

My shipping agent made a mistake to have swapped the shipment of a HT-1A kit and an assembled kit, one to United States and the other to New Zealand.

Based on the latest review, I see the issue is fixed at US side with smile. One the other hand, in New Zealand, the gentleman forwarded the wrong shipment for me and he was pleased with my new shipment.

K9DRPRating: 5/5Jul 21, 2019 22:32Send this review to a friend
Great little rig! Time owned: 0 to 3 months
I ordered an assembled HT-1A from CRKITS, but they shipped me the kit instead. Adam was very willing to do what was needed to make things right, but wasn't able to get an assembled unit shipped to me before Field Day. So I opted to take a refund of the difference and build the kit myself. I'm glad I did.

This was the first kit that I've built entirely by myself. But the instructions (you have to download), and Adam's Youtube video for the build, convinced me to give it a try. It took me quite a bit longer than the two hours advertised in which to put this kit together, but I was determined not to make a rookie mistake. I have never had to wind toroids before, so I sought additional instructions on that (thank goodness for the internet). It wasn't too hard for this first-timer, and the radio came to life with the first toggle of the power switch.

I am very impressed with this little radio. I compared it side by side with my Ten-Tec Argonaut V, on a night with poor propagation and heavy QRN. I could not perceive a difference between the two receivers. I enjoy QRP fox hunts, and working split frequencies is no problem with the XIT on this rig.

I ordered the HT-1A to use in the field, but I find it being my go-to QRP rig in the shack. At $150 I would think Adam would have a hard time keeping any in stock.

Thanks,
Adam

Raspberry pi setup for d4d

Simon C <symen79@...>
 

while I wait for my d4d kit in the mail, I setup Raspberry pi zero with wsjt-x, and vnc from iPad.

should be a fun addition to my portable setup!

looking forward to receiving my kit :)

Simon,

Have you run WSJT-X on a Pi Zero before?  I understand it may not be sufficient for FT8.   I'm thinking of running it on a PI 3 A+ for portable work.

Is the antenna a linked dipole or just a cut for single band?

Re: Raspberry pi setup for d4d

Simon C <symen79@...>
 

Hi Ron,

This was my first run with it on a pi zero, worked fb! Not as snappy starting the app from boot etc as the pi 3b+ which also works great. In the field, I believe the performance/ power consumption of the zero will suit me just fine :).

Don't know what Trent is on about, if it doesn't work, explain my screen shot.

73 all

Simon.

News to me Trent, I've run it successfully on a Pi3 and there are plenty of YouTube videos showing others doing the same.

It runs Ft8, but if there are a lot of stations - a lot to decode then it has no time to get an answer before the next cycle begins. Otherwise it runs ok.

Change decode from deep to normal and try again.

This happens on 20 when the band is very crowded and calling cq. Replying to others is ok.

Checked. Fast, both wideband decoding and narrow filter. Decoder sensitivity seems to be minimum.

Re: Raspberry pi setup for d4d

Ron Stone
 

Simon,

As others have indicated, the Zero will work best when responding to others, and may not complete the decode quickly enough when you're calling CQ.  However, can anyone confirm that the Zero is fast enough even when just responding to someone else's CQ or tail ending - that is, before the next transmission cycle begins?

Re: Photos of Mini Wire Antenna Sample Build

Hi Adam,
Thanks I have received the Mini Antenna Kit. Please send more instructions how to build like in second photo for 1:1 BALUN for a Dipole for the 40m band. How many windings for each wire. What is the exact meaning  A - L, A' and B - G, B' and C - R, C' - B from the manual.

Best regards,
Fred
