I ve at least 3 Chinese nano boards from various sellers, working fine with arduino ide and windows 8.1 (the only problem I have : it need to be run as administrator -giving strange messages when

I have come out of surgery now, and I think I’ll be home tonight and may be able to construct voltage divider on my Heathkit Cantenna to get a attenuated signal that I can further attenuate on

As a linux user the whole problem of drivers is actually transparent for me. For Win10 it was a major pain and I went with a (real not clone) FSTV232-3v3 cable to sidestep the whole thing.? It

There is a design out there to use any Arduino as ICSP ( I have one I made up) and that can be used to load a boot loader or entire program as desired. Also I have a commercial in circuit programmer

Giles Okay. I have one other volunteer for moderator. I will let you both know when I get the group up and functioning. Probably only a couple of days until that happens. Arv _._ wrote:

Alan, You hit the high and low points well.? The biggest thing is we have a known fail. We believe its due to layout. Its not easily fixed for most. ? Your not the only one that wrote that as well

Warren, The -30dbc for IMD of third order is good.? Whats no so good is only 2W. It was actually hard to find that data for a lot of the QRP/low power radios. For many it doesn't exist.?? I never

I have one I built and was thinking of giving it a go.? Glad to see others feel the same way.?? Perfect for the band and power range. 73, KM4OLT Michael

I am unable to achieve IMD products at -30 dBc or better at any power level above 2 watts. I have searched this board and do not find IMD measurements. What Is the consensus on acceptable IMD levels

I can help moderate the new forums(s). I'm an electrical engineer and Extra class ham. Jim

Advantage of Spice simulators is that you can define, or re-define, the parameters of a specific component, or components. Almost everything is programmable. This lets us use Spice simulations for

Hi Arv Yes Arv, in these conditions I want to be moderator. I will call the real technicians when the questions will exceed my abilities to answer. 73 QRO for F1BFU

Gilles F1BFU Thanks for your comments. Moderators do not have to be technical specialists. The task of moderating a discussion group seems more like "herding cats" than verifying technical claims. The

Sorry guys. A Typo on my ZM-2 recommendation. If you “do not” need a metered SWR display. The tune to a dim LED works great except in direct sunlight. In this case I use a small shade.

I would also recommend the ZM-2 tuner if you do need a SWR meter reading. It has a resistive bridge to protect your rig, very fast to tune, and the range is amazing. You could likely tune to low SWR

Hi Mike, The tuner itself does not care how much power you use to 'set' it as long as it isn't *more* than it can handle. It is not impressed if your TX can pin the needle or not. If your uBitx will

Dennis I will keep you in mind for a Moderator. I'm still working on a few loose ends and then will be back on the new test equipment group effort. Thanks again, Arv _._
