[Elecraft] Sub RX and P3
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?

Re: [Elecraft] Sub RX and P3
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 andy.ne...@btinternet.comwrote: Just got the Sub RX and I must say it looks tasty.

Re: [Elecraft] Sub RX and P3
Ed, 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. - 73, Stan - KR7C -- View this message in context: http://elecraft.365791.n2.nabble.com/Sub-RX-and-P3-tp7586555p7586558.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Sub RX and P3
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 G4HUE wrote Just got the Sub RX and I must say it looks tasty.

[Elecraft] Sub-rx or P3?

Re: [Elecraft] Sub-rx or P3?
I'd say the sub-rx by a long shot. For DXing, the ability to listen to *both* the DX station working split *and* his pileup at the same time is a biggie. For contesting, SO2V operation listen around the same band when CQing during slow times is an enhancement. Just seeing the blips is not as effective as hearing the calls.

Re: [Elecraft] Sub-rx or P3?
I've obtained both relatively recently, and my vote would be for the P3. The P3 is quite useful for seeing the calling freq of stations in DX pileups, so in that regard it satisfies one of the functions of the sub-RX. Unless you really need to use diversity or to monitor the audio on another frequency or band, the sub RX has limited additional utility. It is pricy ($700 to $1000+ depending on your choice of filters) and adds considerably to the internal complexity of the K3, making service access more difficult. But it does work well and increases the flexibility of the K3. The P3 is eye-opening. At a glance you can see everything happening on the band segment of your choice without touching a tuning dial. I've found lots of DX with it already before it appeared on the clusters. The display is excellent - very clear and sharp. The functionality of the P3 will get even better as the expected hardware and firmware upgrades become available. 73 Craig AC0DS __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Sub-rx or P3?
I agree the sub-Rx by a long shot. The way to get in and out of a pileup quickly is by following who the DX is working and figuring out the pattern of a split operation. I had a spectrum display in my 7800, and while it's pretty to look at, it's really just fluff.

[Elecraft] Sub-rx or P3?
There are low cost alternatives to the P3, such as (cheapest) an 8 MHz Softrock Lite II board or the more expensive but better integrated LP-PAN, so that it is possible to discover how useful a panadapter is without a major financial commitment. If a panadapter turns out to be useful, you can then later decide whether to add the P3 or stay with the lower cost solution. You can also use the Softrock or LP-Pan as a sub-receiver, but it's not nearly as well integrated as the K3's internal sub-receiver.

Re: [Elecraft] Sub-rx or P3?
There is no comparison between the 7800 and the display of the P3 or that produced by LP Pan. With the later 2, you have so much detail they are of use, rather than just telling if the band is open. It depends on what kind of radio operation your undertaking. If you a very serious Dxer or Contester, I agree the sub receiver is the way to go. If you only a casual DXer or Contester, I would pick the P3, softrock or LP Pan.

Re: [Elecraft] Sub-rx or P3?
For DX, the subrx is a huge plus. It is a tremendous help to listen to a split pileup in one ear and the DX in the other. Yes, you can switch back and forth quickly without the subrx, but at least for me the subrx method is much, much better. It is the difference between getting the DX in a couple of calls and struggling for half an hour. I have both. While the P3 also has some good uses for DX, like the ability to find that one weak signal on a nearly dead band, the subrx is definitely higher priority. For contesting, I find the P3 more useful. I don't use the subrx, and the P3 is good for finding a clear spot to call CQ and to give you a general picture of where the activity is on a band. Everyone's style is different, but that's how I use these tools.

Re: [Elecraft] Sub-rx or P3?
I use my K3 in a diversity mode paired with an ORION ll. My K3 is a single receiver with no P3. You talk about flexibility and performance, as far as I am concerned this is it. Two great receivers, and a third OK receiver, band scope, two transmitters so I can taylor the audio, and the ability to select three different linear amplifiers. A little pricey but great flexibility. George, W6GF --- On Wed, 9/1/10, Vic K2VCO v...@rakefet.com wrote: From: Vic K2VCO v...@rakefet.com Subject: Re: [Elecraft] Sub-rx or P3?

[Elecraft] Sub-rx or P3?
Make my vote for the KRX3. After living for years with a TS850 and literally wearing the label off of the TF-SET button, having the second receiver is wonderful. Being able to listen to the DX on his frequency in one ear and the pileup on the TX frequency in the other, and being able to adjust the level of the two individually or with the balance control is a valuable tool for timing calls... Us little pistols with 500w and a tribander at 40 feet rely on call timing. If I had bigger antennas, a taller tower and legal limit output, maybe the P3 would be a wash with the KRX3, but here at Whiskey Four Little Tower, the second receiver wins hands down. The second advantage of the KRX3 is diversity receive. I often put my main receiver on my tribander and the second receiver on a vertical. Diversity helps manage quite a lot of fade, especially those deep Asiatic Russia CW signals that travel through the Auroral Circle, always a problem here in Florida with a high angle of incidence antenna like I have at 40 feet. You can hear which polarization is winning by listening to where the signal ends up in the stereo image (tribander on the left, vertical on the right, the winning polarization is the strongest in your head). Some may not like this effect (I do!). The third is being able to search for multipliers in a contest environment on the second receiver between calling CQ on the main. This helped me do a Sweeep in SS SSB for the first time in 32 years of entering the contest (I dont use the cluster for SS). Its kind of like SO 1.5 R! You can actually listen on two different bands if you use the AUX RF input on the KRX3 and have separate antennas. In deference to those visual people, especially all my Icom owning friends, I find working split stations with my club's IC7700 (no second receiver, but with a pan display) and Pro 2's (hard to use Dual Watch feature) primitive compared with using my K3 with the KRX3 on the same antennas at the club. The IC7700 is like going back to the TS-850, with me madly punching the XFC button. At least Icom was smart and didnt print the label on the button! Its much easier on a 7800 with its second receiver, but then you can buy two K3's and two P3's for the price of one of those (If you have a sturdy enough table to put it on and have two people to help you lift it out of the shipping crate as Icom recommends in the manual!!!) . There is no substitute, in my opinion, for actually HEARING the pileup. However, a P3 is on my Christmas List :) Lu Romero - W4LT Tampa FL K3 # 3192 --- Message: 35 Date: Wed, 1 Sep 2010 04:30:06 -0600 From: John Harper j...@ae5x.com Subject: [Elecraft] Sub-rx or P3?
