Re: [Elecraft] P3 TX MON envelope display

Is there a link to some photos where I can see what this looks like? I did not know about the SWR/PWR indication. As for the envelope display, I would expect it to be good enough to indicate trouble or not. Years back, I ran a Heath SB-610 which saved my finals one time. The rig went into

Missed that. Guess it pays to RTFM :-) Thanks … Grant NQ5T K3 #2091, KX3 #8342 > > > The sweep width is adjusted in the "ModScale" menu entry. (Admittedly not a > very intuitive name. :=) > __ Elecraft mailing list Home:

Re: [Elecraft] P3 TX MON envelope display

The modulation monitor is like an oscilloscope in that it triggers on the rising edge of the modulation. So the display is not quite continuous - after every sweep it waits for the next positive transition before starting the next sweep. This is especially useful in CW mode so that the

Re: [Elecraft] P3 TX MON envelope display

Out on youtube if you search for "P3 TXMON" you'll find a couple of short (1 min video) of an operator showing a SSB and CW envelope on a P3 with the TXMON option installed. Tom, W2YF >>> >>> On 2/3/2016 8:26 AM, Barry N1EU wrote: >>> Can someone with the P3 TX MON please describe the

Re: [Elecraft] P3 TX MON envelope display

Do you have a link to a youtube video showing a phone waveform? The only video I come up with is https://www.youtube.com/watch?v=CHugxEpj6bg with NB3R showing only a cw waveform. That's why I posted my question in the first place, because I've never seen a phone waveform. Barry N1EU On Wed,

Re: [Elecraft] P3 TX MON envelope display

Barry, I don't have one, but I have seen them in use. The envelope display looks like what I see on my analog 'scope. It may be digital, but the refresh rate is fast enough you will not be able to differentiate it from an analog display. 73, Don W3FPR On 2/3/2016 8:26 AM, Barry N1EU wrote:

Thanks Tom! That's just what I was looking for. 73, Barry N1EU On Wed, Feb 3, 2016 at 10:05 PM, Tom Crayner wrote: > Sure. Try: > > https://www.youtube.com/watch?v=cx3ZeI3FlHk > > Tom, W2YF > > > On Wed, Feb 3, 2016 at 5:01 PM, Barry N1EU wrote: > >

Re: [Elecraft] P3 TX MON envelope display

The envelope display is not a “snapshot”, but it isn’t quite real time either. Close, but if you’re used to using a scope for monitoring, you won’t call it “live”. Also, the vertical height of the display is always normalized to the peak RF signal and there are no sweep width/rate

[Elecraft] P3 TX MON envelope display

Can someone with the P3 TX MON please describe the envelope display in ssb/am modes? Does it work like a real time oscilloscope (dynamic) with changing display as you speak or does it take static snapshots of the RF envelope? If static, how often does it update those snapshots? Thanks & 73,
