IT is an issue. An external switchable filter can correct it until a more complete solution is built and sold. Fixing issues in a radio that was mostly a group design is what "WE, the collective

Good morning Jack, ? Thank for all your help and patience. Ran out of time yesterday so I’m back at it this morning, I’ve add the second bracket and uploaded again but still getting error

I bought the shield assembled from TAPR http://tapr.org/kits_20M-wspr-pi.html about 2-1/2 years ago.? Lots of plans online to roll your own but at the time my junk box was lacking.? I was originally

Kees, Why not an external board that takes RF inputs RF out to connector and has Relay for TR, the four filters 4 more relays for switching and accepts? the Raduino signals needed: TX-V+? to signal

I like it, as a Christian I am continually reminded not to pass judgment too quickly & most importantly to listen patiently to BOTH sides of the argument ? before doing anything, be slow to speak &

I have an ELEGOO display that I am working with at the moment.? Some of the Chinese brand names are truly strange!

I've been looking at the AA-30.ZERO every since it came out and am quite interested in it. It will be interesting to see where this thread goes. I too am thinking a Nextion display would be a nice

I usually prefer the P-FET solution - prices have come down for these, around a buck per P-FET. And not only the price, but more & more P-FETs with very low V-forward drop. No fuse to replace (if

Yes, it is!, Allison. I like the attitude of this Ukrainian company bcoz of releasing such a fancy device for us. // hiro, JJ1FXF 2018/08/08 23:28、ajparent1/KB1GMX <kb1gmx@...>のメール:

Dennis, What about using the Nextion LCD for your project? Nextion LCD presents more flexibility for Arduino, I guess. I got this AA-30.ZERO bcoz I supposed that I could measure inductance of coils.

Please look at the K5BCQ site (qsl.net) for an LPF / BDF filter unit with a switch or another with automatic switching. [image: BPF2D.JPG] [image: 6bandfiltera.JPG] Gilles F1BFU / FR

For 90$ and rig expert has a proven track record of making antenna analysers its a great deal. I may pull the trigger on that one. Allison

OK, where do we go from here on the uBITX .....what are the plans ? As they say "whatareyouupto" 1) The simplest solution I can think of is a small board, about the size of the existing 4 LPFs with a

Have you posted the design? It sounds interesting. Howard

bob, It’s a new type of Arduino which seems very exciting to me. Thanks for your input. // hiro, JJ1FXF 2018/08/08 21:04、bobh_us <rwhinric@...>のメール:

When I was working part of my job was the calibration of instruments for a company that made polyester material. We had equipment that was sent off on a schedule to check it met standards. Our on line

So to finish your analogy for you, you bought a low cost black powder kit and expect it to work exactly like an expensive complete model from a major manufacturer. As to your courtroom argument, I

Great Job, Dan! I have something related in the works..... Hope to share it soon.

To Bill G6ATO & John N3ODE. Well said! I probably had more enjoyment building a snazzy enclosure than possibly anything I can remember. Just built the V4 ubitx and yes the rx audio is horrible to say

I have one and am working on an Arduino sketch to interface it to an LCD graphic display.? I hope to package it in a 3D printed case as a battery powered,? handheld device.
