Re: W8TEE vft/tft questions
Hi Jack, thanks for answering. I have been watching the debug code you mentioned, and the output has changed since things went south. I added some Serial.print statements of my own.? After watching

Re: Raduino issue
I did pull the raduino out and booted it standalone. It still showed only the firmware. Would it get locked in factory mode?

Re: toggle for low output and max output?

Allison, I think VK2ETA's approach is good enough for adjusting the power out by a few dB. He moves where the transmitted signal lies within the 45mhz filter response, taking it down the skirts to

No, just no.? We are working with a linear or trying to be linear.? Plaing with the voltage to the finals would be bad. Allison

Re: Raduino issue
Thank you! I thought about that. I tried reverting to the original firmware and it was the same. Was tempted to disconnect the entire encoder but left it as is. Will give it a shot.

Re: Raduino issue
Hello Sam, There is a good chance your Raduino is likely working and you have an issue with the encoder. Since it displays the version at start and nothing more after that it certainly looks like you

Re: toggle for low output and max output?
#ubitx
As this is for low power, how about separating out the power wire going to the final amp stage and using one of the buck or buck/boost converters from China that is on ebay ? They have a pot on them

Re: spurious signals on FT8

Input levels to any transmitter for any digital modes ARE critical. There are guidances published in various places about how to set up the modulation levels, some give exact instructions for good

Re: Raduino replacement
#bitx20
Sure, its fun. Just like girls used to be.? I may just order another whole kit myself too. I can always build an analog VFO for the one I have. That would keep me out of trouble. Best wishes. Mike

Re: RF power chain mods and improvements..
Mike, That is true but let me finish first.? ?You can buy them and try them too and see if with a sample size greater than 1 it behaves. As a QRP rig it RX power needs are really good at around 160

Re: Raduino replacement

Good idea, Bo. The only thing I worry about is, what if there is more than just a Raduino that is at issue with the one I received. I don't want to sell you junk. If you were nearby in NY State I'd

Yep! Heat it, blow hard, punch hole with a tapered punch, moving it so it doesn't get stuck.

No matter how you do it it will require hardware with my mods or no. The easy solution is hard to implement as the places to put it are scarce and they must be in the TX only path. The most seemingly

Re: share your BITX success stories
I found spurious signals doing FT8, and reduced the audio (and resulting output power) to reduce them. I'm gonna meter it somehow to keep it optimum. Tnx input! Bo
