There is something call sub groups that has been long ignored Arv.

Hola, ?puedo alimentar mi uBitX-6 con 13.8 voltios? Tengo dudas ya que Arduino recomienda alimentar con 12 voltios. 73 Ca4wqp

Hi, Rene said from before that he is using a dummy load, so that is not the problem. I suppose there could be a problem with the raduino/display connection.? That could be sorted by doing a

The ventilators that Musk donated were imported from China, he's not producing them.

Rene There is a fine transceiver in that box, so do not quit please. Try tuning slowly, is it better?? if encoder is very very bad, request replacement.? if not so bad, it may be like mine, just he

Rubens I doubt this is due to bias if other bands are okay. My v4 was outputting about 2 to 3 watts on 40m, while more than 7 watts on 80 and 30 meters. Add a few hundred pF in parallel with C81,

Hi Rubens, The first part of this document has instructions for setting PA bias: http://ubitx.net/wp-content/uploads/2018/06/uBITX-tune-up-instructions.pdf 73, Andy, KG5RKP

Help !!! I have an uBITX v4, it has low power problems in 40m, so I would like to check the power output settings. How do I adjust the idle current in the uBITX v4? I have a milliammeter connected to

Gordon Yes. Seeing Jacks post about the new group relieves some of the pressure to do more here regarding ventilator development. I will be doing research over the next couple of days to see if some

Well, if you guys can get those ventilators made within the next few days, that would be great. Otherwise people will die. I don't know what else to say. Get your companies cranking out free

The designs for cost effective ventilators already exist. If production facitlites were to adapt to be able to produce existing curretnly FDA etc approved ventilators then that may be the fastest way

Hi arv --- whatever works best,, I'm fine with -- there is this new forum now and I think quite a few peopple are there. It is possible that SOME people in the wider group would like periodic updates

Farhan Still thinking about how to handle traffic related to this mostly-ham effort and still not offend the rest of the group? What about making a specific #topic header so that those not interested

Gordon Still thinking about how to manage the "hams working on ventilators" traffic versus the rest of the BITX-20 group discussions. Wonder if it would work to let the ventilator traffic continue but

Hi Barry, Thanks for sharing your experience.? I'll start a search for something mechanical! 73, Andy

Thanks Curt!? I see what you mean about touch-specific 'keyer interfaces'.? I explored the capabilities of the BITX and ?BITX but neglected to consider a more 'universal' connection.? I had to

recommend you join the group: /g/VentilatorDevelopers developer efforts there. Gordon

thanks, we will survive! gordon [email protected]> wrote:

Yes I would be willing to build some of these. The largest medical center in our portion of the state has 11 respirators available. I have nanos and 2 line displays in stock. -- 73 Dave ADOB (

I have tried various touch paddles in the past and did not like them. One model (home brew), would stop working after awhile. I never found the cause of this issue. The second one I purchased and it
