P3 in TX consideration/suggestions ... maybe stupid

[ik1bxn]

Hi guys !
I noticed P3 is out of game at tx time, in rx it is simply wonderful. I wonder if it should be possible/useful/intelligent to display at it during tx time info such as :

RF power
SWR value
ALC value

in big fonts in order to read values at a glance

Wonderful ,in my opinion, it should be to have at it in future a digital vector wattmeter (maybe it's already in plan)

What do you feel ? Is this a stupid and void proposal or not ?

Thanks everybody for reading, 73 de Giorgio

Great ideas, some of which are already on the list. Note the "SENSOR"  
connector on the back of the P3.

Thanks Wayne. Yes, just looking to the rear panel I thought vector wattmeter (or something like that) maybe is already in plan :-)

Hi Giorgio

It would also be nice if you could  define makers A and B to indicate signal level on the screen.

If you then could indicate the difference between marker A and B this also help. It would  also be nice if marker A and B could be set as peak reading markers.

Peak or level markers in all forms are most welcome.  Maybe even the ability to tune marker A or B  to any  peak and read the value on the screen.

If the P3 is going to be used for TX measurement levels the ability to define a TX mask would also be a nice feature.

If you are going to monitor your signal on the air a TX menu screen with a reduced span down to say 20 or 40 khz,  peak markers every 5khz  would be nice. This feature would give  you the peak level of your TX IMD at these points. This would be a good way of ensuring a clean signal. This  TXTEST feature in Linrad is superb for this application.

I suppose good wine takes time!

The are many SDR receivers  that  have been on the market for years now,  even  these dont have these features yet. Many of the designers and users of these products dont appreciate the value of these products as spectrum analyzers and measuring tools.

Ciao John, I quote 100% what you wrote ! My dream should be to use the fantastic P3 also at tx time having there all info it's useful to have in order to be sure that tx is optimized.
I intend P3 as a powerful measurement instrument not only a panoramic useful device .Right now you have to buy external 3rd part device such as LP-100a or LP-500 to get this kind of info/values.
Of course it will take a time and a cost to develop this features, that's not up to me to decide if proceed of course.  
I proposed to start with the info all already available at K3 (I think) such as RF power, SWR and ALC just to start giving to P3 a role also in TX.
