I just had a QSO with K2OCA who is only a couple of miles away. He was running significant power, so even if you didn't hear me, you might have heard him. I'm getting some significant QRM from 2275 this evening.

I agree with you opinion, yes There is not enough explanation for them :)

I liked it the first time I implemented this feature. 

So I adopted it as a basic specification. That is, if no setting is made, 'TX' frequency is displayed unconditionally.

However, it is inconvenient for users who are familiar with the existing method.

So I decided to let the user choose by uBITX Manager.

Ian :

Thanks for the reply. I noticed that option in the uBITX Manager but I couldn't find any documentation on what I meant.
Now I know, so I will give it a try.  I am not sure that this will "fix" the issue in switching back and forth between CWU and CWL,
but I will recheck after I try with this option enabled. 

What I have observed is  that the RX Frequency stays the same when you switch from CWU to CWL, but the TX frequency is changed, which should not
be the case.

Thanks for the clarification.

Cheers

That's extremely interesting and informative, and completely contrary to what I'm trying to do. I like the answers about using the pot on the board to lower the output power. Excellent. I'll probably do that.

But my initial problem was that, with a particular battery pack, the rig overdrove my tuner, making it fail to tune. Thankfully non-catastrophically, (i.e., it didn't catch fire) but it still wouldn't tune, and indications were that the power was out of range at the top end.

I realize that most users of radios want to MAXIMIZE output power, and then level it across as many bands as possible, so they have lots of output power in all of the bands they want to use. But I don't want to increase the power. I want to control it. The battery's specs list it at 12v @ 5A. So it has plenty of power and shouldn't limit the transmitter. But that's not my issue. The issue is that with that battery supply, there's TOO MUCH OUTPUT. If I run it from a bench supply, it doesn't do this. If I power the bench supply from the battery, it doesn't do this. I'm charging a battery bank I have with a 12vdc output jack, with a limit of 3A, that I'm going to test to see what IT does.

But I don't WANT to maximize RF out. I want to keep it within the limits of my tuner. I will try not setting a limit on the amperage and just try lowering the voltage, and see what that does, if limiting the amperage causes Bad Things.

Am I not being clear as to my goal in this instance? I'm trying to assemble a portable setup to take into the field for battery operation, but everything needs to play nicely with everything else, and the battery I was trying wouldn't play well with the tuner. I'm also testing to see if the problem might have been with the antenna or with the tuner, by testing different antennas and different tuners, to see if the problem actually exists with the BATTERY and not something else. If I can do it with a different battery pack that doesn't overwhelm the rig, PERFECT. But if that's going to cause bad harmonics or spurs or splattery signal, then that's not so perfect. I want to find the actual CAUSE of the difficulty, not just slap a band-aid on it or treat symptoms, but so far the assumptions I keep hearing are that I'm trying to maximize output, which is not the case. If I wanted to maximize output, I'd be building different sorts of radios, not QRP rigs.

I take them seriously as it impacts future upgrades of the compiler which may
not accept it at all.  That and its a basic fix.

I'm an old Pascal user and wild type changes were not permitted.  

Also old assembler writer where you can do terrible things and
maybe survive.... ouch!
