Sub RX and P3
Locked
 
|
Just got the Sub RX and I must say it looks tasty. However, I am puzzled by the display on the P3 (another tasty toy I would not be without). I have read the KE7X tour de force on the Elecraft kit and the P3 manual and the other Elecraft manuals and unless I am going soggy in the brain department (golly I do hope not - I still have so much to do) my P3 display puzzles me.
The sub RX shows up in magenta (I seem to recall KE7X calls it cyan but trust me its magenta) on the P3 but when, and only when, I put the K3 into SPLIT mode the magenta bar on the P3 (which shows what the Sub RX is doing) has a central highlighted portion which is really bright. When I move out of SPLIT its a standard magenta. I accept that this is a really usefull way of telling me I am in SPLIT mode but I cant find a reference to it anywhere - so please put me out of my misery, where is this reflected in the documentation?

The second receiver IF really isn't showing up on the P3, you are only
seeing the IF from the main receiver. However you do get to see some very nice visual effects on top of that IF display. VFO-B will show up in magenta and will be the approximate width of the IF filter selected. If you have SUB-rx enabled, then it is controlled by VFO b, and its filter width will establish the width of the magenta display. While It is colored magenta, it will turn red if you have SPLIT on (because you are going to transmit on that VFO B setting). Heaven help you if you are working DX in split and don't see red -- the "UP Police" will be on you in a blink of an eye! 73, Bob, WB4SON On Fri, Apr 4, 2014 at 3:25 PM, ANDY NEHAN <[hidden email]>wrote: > Just got the Sub RX and I must say it looks tasty.

Andy,
You are confusing "markers" and "cursors". The VFO A receive frequency is denoted by a green "cursor" and VFO B by a red cursor (when SPLIT is active). The markers, MKRA (green) and MKRB (magenta), are used with the Select button to QSY the K3, but they do not necessarily indicate the active frequency of their respective VFO except when that button is pressed. Page 16 of the Rev D manual has the full details. If you put the rig into SPLIT mode, you can see all 4 indicators at once on the P3 screen if you want.

Hi Andy,
First it's easier to see what's going on if you turn off the A and B markers. You just want to see the cursors to get a better handle on how they operate. And you want to activate the VFO-B cursor in the P3 menu. VFO-A has a green cursor. VFO-B has a Magenta cursor. There is no separate cursor for the SUB RX. It is just the VFO-B cursor. If you choose SPLIT there is an additional cursor in Red. The Red cursor denotes your transmit frequency when it differs from VFO-A. You'll also see the Red cursor if you choose XIT. The Red cursor may be the same width as the magenta cursor so it might be invisible when operating SPLIT. If you fiddle with the bandwidth knob after pushing BSET you'll be able see the difference between the Red and Magenta Cursors. 73, Mike K2MK

Boy if that ain't the truth. I still keep messing up with that.
