Has anyone tried to us the LDG Z-817 autotuner meant to be used with the FT-817 with the uBitx.

That won’t help with what I want to do. I run normally my station on FT8 remotely using team viewer. I currently have a manual tuner and I want to be able to control the tuner using the cat breakout i

Sounds like you want a Heathkit level of documentation. Well my 1976 HW104 cost over $600 in 1976 dollars. This radio will cost you less than $150 in a nice enclosure. For me the satisfaction was in t

I’m planning to build a version of the K3NG auto tuner as well. I am looking at using a Sainsmart 16 relay module (Amazon $14.99) for the L&C and a 2 relay version for the hi/lo and antenna switch. N9

Yes. I have been using it for 4 months. WAS in 3 months FT8. This is a new problem.

I suspected a sticky relay. I’ll try replacing it.

I replaced all the relays with Axicom relays. It wasn’t too bad to get the old ones out with a solder sucker. Thatfixed the problem. Thanks for your help.

Has anyone tried using a buck boost module to raise the finals voltage supply? I’m worried about the noise from the supply ending up causing spurs on my output. How high have you successfully run the

I had the same issue. I replaced K1 with the axicom and it fixed it.i only run about 15 watts on 80 meters, but I was switching inductance on my ant tuner often while in transmit. I think that may hav

K1 is the Transmitt/Recieve relay. It was sticking in my v4

That looks great Jack. Are you going to sell a kit?

I have a HW104 with solid state finals and was thinking of doing the same thing.

I use omnirig with com3 to communicate with WSJTx but I cannot get Hamlib to connect

What is the title of the new book? I looked on amazon and didn’t see anything with those projects

I put 2 1:1 audio transformers into my V4 and put 2 mono jacks on the back that I run to a $7 usb sound card on my pc. I ran the nano’s usb to a connector on the back for CAT. I put ferries on the usb

My power supply regulator failed. The crowbar circuit kicked in at 15v and blew the fast blow fuse, but my board is dead. The voltage could have gotten as high as 27v before the fuse blew. The 2 amp f

Thanks I’ll try that

Back on the air. It turned out to be a shorted reverse protection diode. I’m not sure how it got blown by the overvoltage spike unless it exceeded the PRV. Anyway, very lucky. thanks for everyone’s he
