Re: [Elecraft] P3 cursors
Guess I don't understand what all the fuss is about. In standard mode, there are two cursors on my P3 - one green and one sort of purplish (I have a partial color blindness, but there is a distinct difference between the two cursors, even for me). Even if you're not operating in SPLIT mode, when you tune the VFO B (the purplish marker) away from the frequency of VFO A, it stands out quite prominently on the P3 display. I operate mostly CW. When a split operation takes place, and I tune somewhere into the piluep I might typically have reduced the SPAN to 20 kHz so there's 10 kHz on each side of the DX operating frequency. As I tune the VFO B (most often it's actually the sub-receiver so I can also hear what's going on in the pileup), you can see an obvious gap between the two cursors. Personally, I enjoy cruising through the pileup, trying to find who the DX is currently working, trying to quickly discern a pattern (if any) of the DX operator. When someone in a cluster spot writes that he worked 'em, it is most often something like QSX 14027.5 as opposed to up 1.375. With the sub-receiver engaged, split engaged and the difference in color between the two cursors, I guess I fail to understand whey there would be a huge need for anything else - at least anything else relating to the P3/K3 functionality that already exists. I think any reasonable operator would only accidentally operate on the DX frequency once or twice before it became a habit to engage SPLIT and then split your xmit frequency. If a given op consistently makes the same mistake of NOT operating split, a bunch of ugly descriptives come to mind!

Re: [Elecraft] P3 cursors
Thanks Joe. I hadn't noticed that. I seldom use RIT/XIT when working split, but I played with that to demonstrate what you're saying. Didn't realize the cursor actually changes color (on VFO B/SubRX) from purplish to red - I just knew it was quite simple to distinguish the diff between where I was listening and where I would be transmitting! My partial color-blindness is referred to as red-green but I have no trouble seeing the obvious green line for the VFO A and the other color for the VFO B. My affliction is revealed by the test of pages with all the colored dots. (Wechsler or something like that.) People with normal vision see numbers - the numbers tend to stand out distinctly among all the colored dots. Those with red-green color-blindness (surprisingly common) can eventually find the numbers, but they don't leap off the page like they do for normal people. Fortunately, stand-alone, distinct colors (like the red and green of a traffic light!) do not cause problems.

Re: [Elecraft] P3 cursors
Hi Stewart, As I am not familiar with the P3, and I do not know how many markers are available, but if several markers are available then your suggestion if followed would remove a lot of mental arithmatic during a DX pileup. I use my Perseus as a panadapter, and it displays the frequency difference (and amplitude difference) between a signal at Marker1 and other signals marked by the other markers, when in delta mode. As just one of several examples. As do many others, I attempt to discern the DX station's listening pattern in a pileup before calling. By placing Marker 1 on the DX's frequency and the other markers on the frequency of each station being worked, the listening pattern in most cases soon becomes clear if the marker deltas are displayed. No mental arithmatic :-) Coupled with Quick Split, a powerful combination, but that's another subject. 73, Geoff LX2AO On May 19, 2012 at 07:52 +0200, Stewart G3RXQ wrote: With a high proportion of operating now involving 'Split' it might remove the mental arithmetic involved, and help to reduce the number of Up Up's ;-) 73 Stewart G3RXQ __ 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] K3 psk31 transmit problems
Hi Frank, Does the K3 show any indication of getting the audio signal from your computer line out ( or speaker out) cable? You can put the K3 into TEST mode and not transmit while you are checking levels. Also you need to adjust the line in gain of the K3 to show the 4-5 bars on the ALC meter then set the power control for what ever power you want, like 25 watts. See the instructions in the manual on how to set this up. It is different than how to use other radios. I also presume you have selected line in on the K3 audio source menu. If you have a working serial cable then you can tell DigiPAN which port to use and to use RTS or DTR. Then make sure in the K3 you have turned on PTT for one or both of those two signals. You can test this with the K3 in TEST mode as well. I use fldigi and flrig using a serial cable and using PTT via CAT to work PSK31. Far more capable program than DigiPAN and pretty easy to use. Free also. DigiPAN is a really old program though the MixW web site says a new version is being worked on. 73, tom n4zpt On 5/19/2012 10:59 AM, kf4clo wrote: Hi All I want to thank everyone for thier help-I still haven't resolved the getting Digipan to key the K3 using the line in-line out,lineout-line in,but I'm still working on it.

The transmit cursor is present when transmit frequency is different from the main receiver frequency (when the K3 red delta F LED is on) even if one turns off the VFO B cursor. A few months ago, an Elecraft customer asked Alan if a monochrome P3 waterfall option could be included in a FW update. To no fanfare, the option appeared in the menu after the next update. It wasn't discussed on the this list that I know of and I suspect that almost no one knows it's there unless you spend a lot of time studying your P3 menu options. The customer was me. I'm one of the 0.001% of the male population with no color vision [we're all male]. My wife explained that the waterfall background was very dark blue [looked black], and the weak signals were dark blue [looked black I guess, I couldn't see them]. They had to get to S6 or so before I could discern them. In monochrome, I can see super-weak signals I can't hear. I can even discern if it is CW, RTTY, or some digital mode in some cases. Obviously, I miss out on quite a bit of the dazzle of the Tokyo-By-Night radios that light up like the Ginza. Those manufacturers would have done nothing for one customer, of course. More basic, I'd have never found anyone to ask. The P3 cursors are lines for me. In fixed-tune mode, my receive frequency cursor moves with the Big Knob making it really easy to find regardless of color. Depending on where I have the CW BW set, it may also be a little fatter. In split, my TX frequency appears as another line, always higher in frequency and it moves with the VFO B knob. I've never heard the Up Cops sending DOWN. It too is easy to find. Next to the TX LED is a Delta-F LED that comes on if I am not transmitting on my receive frequency ... for any reason whatsoever. Over on the display, there will be a little arrow pointing down to VFO B if I'm split. There are LED's around the RIT knob that light up if it [or XIT] is engaged. While I would take issue with Joe's use of inexcusable as a bit harsh, I can't think of many more things Elecraft could have done to tell me that I'm not transmitting on my receive frequency. And they've managed to do it for a ham who couldn't see any difference when color TV came along in the 50's. Nice going!! I can't see the numerals on the keypad either, but it's not a problem, I know what a key pad looks like.

Re: [Elecraft] P3 +12V mod for K3
My apologies gentlemen. Although the cable is shown in the illustrations (Fig 5 and Fig 7), showing that the KPA3 was removed with cable still in place, I failed to point that out in the procedure. Also, Figure 6, showing the recommended way of loosening the KPA3 connectors, was taken of a K3 without the sub-receiver and AUX antenna input so it does not show the cable. I can see how that was confusing. As Brian found, removing it adds a lot of steps to remove the KIO3 board along with the two pony boards from the rear panel unless it's used to connect the subrx aux input to the KAT3. The cable has enough slack to slip it around the KPA3 board as it is removed and replaced. Often that slack is in the form of a loop between the KRX3 module and KIO3 board that needs to be pulled into the KPA3 enclosure. 73, Ron AC7AC -Original Message- Did the +12V mod to my K3 with Sub RX yesterday. As you say the instructions did not mention the Aux cable, however I found that moving the cable to the rear of the K3 and then extracting the PA towards the front was no problem.

Re: [Elecraft] P3 cursors
Hi Geoff, I seem to have muddied the waters by bringing Split into the cursor delta discussion. Leaving aside changing of cursor colour (colors) and RIT/XIT (which are irrelevant as many SSB splits as they wider than those controls), my original request was for the P3 to show the difference in frequency between the two (2) markers. Wish I'd not bothered...

I use my Perseus as a panadapter, and it displays the frequency difference (and amplitude difference) between a signal at Marker1 and other signals marked by the other markers, when in delta mode. As just one of several examples. As do many others, I attempt to discern the DX station's listening pattern in a pileup before calling. By placing Marker 1 on the DX's frequency and the other markers on the frequency of each station being worked, the listening pattern in most cases soon becomes clear if the marker deltas are displayed.

Re: [Elecraft] K3 psk31 transmit problems
Frank, Yes, use the same cable that you use for K3 Utility - note which port is being used. Tell DigiPan to use either DTR or RTS to key the K3 and tell it which port to use, then go into the K3 menu for CONFIG PTT -- KEY and set the PTT to either DTR or RTS (the same as you told DigiPan to use). The only downside to using DTR or RTS is that when the computer is started, those lines will be tested and will become active for a short period - the cure is to boot the computer and then turn on the K3. 73, Don W3FPR On 5/19/2012 10:59 AM, kf4clo wrote: Hi All I want to thank everyone for thier help-I still haven't resolved the getting Digipan to key the K3 using the line in-line out,lineout-line in,but I'm still working on it.

There is never a reason to turn QRQ off. It improves the sound of the sidetone when QSK is on at any speed, although it doesn't make much difference in the transmitted signals below about 33 wpm. It is automatically off when the K3 can't support it, which is when you are in SPLIT or have RIT or XIT on. The ability to turn it off is a vestige of the initial pre-beta implementation, when it needed to be turned off in order to use SPLIT/XIT/RIT. But Wayne made it automatic, so this is not required.

Re: [Elecraft] K3 - RX audio degradation with ANF
I hear it. I have always heard it. Its always been there. I think the distortion you are hearing and seeing in the waterfall you looked at is the notch in the audio itself and the ANF routine's hunting around for the frequency to notch as it samples the audio its being fed. Within the audio spectrum of a voice there are many frequencies, and they are constantly changing as speech is being produced. The tone (of the carrier) you are trying to notch also falls within those frequencies. The notch produced by the ANF has a finite width and depth plus or minus several cycles, as you noticed in the waterfall, which has a rise time and a fall time. When that is superimposed over a voice, there is a comb filter like effect in some frequencies adjecent to the tone you are notching as the automatic notch routine samples and then attempts to blank the interfering tone. We are talking about notching audio here, ANF cant magically get rid of just the tone and leave what is being covered up by the tone alone, it has to get rid of ALL the energy in the spectrum occupied by the tone, plus or minus the notch filter width and depth, so there literally is a hole there, and it moves as the voice and the tone mix. You hear the hole, and notice that something is missing. The hole moves around as the interference is blanked and the ANF refreshes its decision at whatever frequency it samples of what it needs to blank. That's why you dont see it in the manual notch, that one does not move around on its own. At least this is my long winded guess to what one hears here. K9YC may have a better way of explaining this than me (Im a duffer, he's a pro at this game). Ive always heard this to a greater or lesser extent in any radio or device that notches audio frequencies automatically. So called feedback destroyers in stage and studio audio have the same function as ANF, I hear this effect on them as well to a greater or lesser extent. They have gotten so good lately that it is barely preceptible, but its there, you can see it on a spectrum analyser. (Google Sabine Adaptive Audio to see a representative device, their older devices sound quite similar to what you hear in the K3 ANF; the newer ones are truly magical!). I dont think that it is *THAT* objectionable... It is there, I hear it, but I know why it is happening. Is it normal? Maybe. Could it be better? Possibly. I find it acceptable. Its a great aural reminder that you have the auto notch turned on! -lu-w4lt- --- -Original Message- From: elecraft-boun...@mailman.qth.net [elecraft-boun...@mailman.qth.net] On Behalf Of Tim Tucker Sent: Friday, May 18, 2012 10:57 AM To: Elecraft Reflector Subject: Re: [Elecraft] K3 - RX audio degradation with ANF ANF is the common use abbreviation for Auto Notch Filter. A lot of rigs use that nomenclature. The K3's ANF on SSB has not worked correctly IMO for several firmware releases. Someone posted a fix a while back that involved resetting back to factory settings, rolling back to a previous firmware, reloading all your settings and then loading the current firmware. That's a lot of work and I was hoping a more elegant fix could be implemented in a firmware update. In my experience, the issue isn't so much extreme distortion on the signal, it's that it doesn't notch the offending signal properly. To reproduce, watch your RX signal with a strong carrier on a waterfall with a computer application like MixW. Turn on the ANF and you'll see that the K3 notches on either side of the offending carrier, but not actually right on the carrier. If you have good ears, you can hear this yourself. The manual notch works fine, of course. I haven't tried the latest beta firmware, so I don't know if this issue has been addressed yet. It needs to be addressed, though.

(Google Sabine Adaptive Audio to see a representative device, their older devices sound quite similar to what you hear in the K3 ANF; the newer ones are truly magical!). Professional musicians are the pickiest sound folks in the world. What the K3 does would be most unacceptable to them and I can say that, for sure, I have never heard similar at any professional music venue. The musicians would strangle the audio tech if it were so. All professional automatic notch filtering used in the music field is done at the what we call the audio level. It is their ONLY level, as they are not working with IFs etc. Hence, I can only assume that the audio level automatic notch filtering found in the K3 is not yet up to par.

[Elecraft] Erroneous P3 Bandwidth Display
The latest P3 firmware seems to have a slight problem. Set the P3 in Fix-Tune mode. Tune both receivers so that both bandwidth cursors will appear on screen Go to KRX3 (hold B SET) Go to USB (hold ALT) A green LSB bandwidth cursor will appear on the display for the KRX3 even in the USB mode. It doesn't make any difference if the cursor is in the U display mode or the BAR display mode, its still there. This shows up on both the P3 screen and the external screen. Is this normal?

Re: [Elecraft] KPA500 / KAT500 remote
I can't answer for the KAT500, but the KPA certainly can be operated in this fashion. The KPA needs the K3's PTT output connection, and its operation is enhanced if you connect the band signals. It also has an RS-232 port that allows you to monitor and control the KPA from a computer. So the answer as far as the KPA500 is concerned is a definite yes.

Re: [Elecraft] K3 - RX audio degradation with ANF
I think we may be comparing apples to oranges here. In the K3 digital ANF, the notch filter is looking for coherent signals. The premise is that audio is less coherent than a CW carrier. Thus the ANF finds the coherent CW carrier and notches it out, leaving the remaining audio. On May 19, 2012, at 4:27 PM, Bill wrote: You said, They have gotten so good lately that it is barely preceptible, but its there, you can see it on a spectrum analyser. (Google Sabine Adaptive Audio to see a representative device, their older devices sound quite similar to what you hear in the K3 ANF; the newer ones are truly magical!). Professional musicians are the pickiest sound folks in the world. What the K3 does would be most unacceptable to them and I can say that, for sure, I have never heard similar at any professional music venue. The musicians would strangle the audio tech if it were so. All professional automatic notch filtering used in the music field is done at the what we call the audio level. It is their ONLY level, as they are not working with IFs etc. Hence, I can only assume that the audio level automatic notch filtering found in the K3 is not yet up to par. I say yet as that is the advantage of updates. At some point in the future, the ANF can be brought up to higher standards.

Re: [Elecraft] OT: Dayton New Equipment Show
The Flex 6000/6700 is an on frequency direct digital conversion radio - that is a 16 bit analog to digital converter operating at the front end of the radio with no intermediate conversion/IF and filtering stages. In addition, all of the DSP is contained in the radio (no more PowerSRD). The new software for the Flex 6000/6700 (reportedly PowerRX) is essentially a glass control panel). A general purpose computer is required for PowerRX but communication between the computer and transceiver is via TCP/IP which means the computer can be anywhere. Audio input and output will be available both on the transceiver and from PowerRX (interesting for remote operation scenarios). The issue will be the severely limited dynamic range of the 16 bit ADC. Without effective AGC ahead of the ADC there *will* be overload problems on crowded bands (e.g. 160/80/40) where any transceiver must deal with many extremely strong (local) signals while maintaining maximum sensitivity. With AGC, the strong local signals will cause blocking as the gain is reduced to prevent overflow of the ADC.

Re: [Elecraft] OT: Dayton New Equipment Show
Joe, I'm not sure some of your suppositions are correct. First of all, the ADC samples at a significantly higher rate than the incoming RF (for HF), at 245.76MHz. Then, those samples go through decimation inside Digital DownConverter (DDC) in the FPGA, and the higher the decimation, the more the processing gain, and therefore added bits. I believe the typical assumption is that you gain the equivalent of approx. one-half bit (3dB) of dynamic range every time you decimate (divide) the sample rate by two. This is real gain, not some imaginary trick or magic. If you start with a 245.76MHz sample rate, and end up with 240kHz (example), you could achieve a processing gain of an additional five bits, or 30dB. If my quick math is correct. All without AGC or other games. Throw away at least one A/D bit, so 15 bits(ADC) plus five bits(proc gain) yields 20 bits, or about 120dB of dynamic range. I must be a little off, as I saw one note on the Flex reflector that they think 153dB or so of dynamic range. Maybe by lowering the final sample rate some more, or not tossing all of one bit of the ADC. I believe Mitola suggested that 130dB of dynamic range is adequate for HF, I'm not sure if that includes noise from storms, etc. BTW, the new software is called SmartSDR. I have been playing with DDC receivers for a couple of years now, and I firmly believe they will be the future. I suggest that thorough research of DDC-based receiver design will alter your perception. It did mine. I love my K3/P3, and do not plan to replace it anytime soon. It just works GREAT, and is a nice compact box without requiring a computer to use. But, I was very tempted to by a Flex 6500. That is, until I saw the $200 per year charge for the software. Technically, very leading edge. Marketing, you decide. Hope this isn't too off-topic. 73, Terry, WB4JFI -Original Message- From: Joe Subich, W4TV Sent: Saturday, May 19, 2012 7:29 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] OT: Dayton New Equipment Show The Flex 6000/6700 is an on frequency direct digital conversion radio - that is a 16 bit analog to digital converter operating at the front end of the radio with no intermediate conversion/IF and filtering stages.

Re: [Elecraft] OT: Dayton New Equipment Show
Hi Joe, Guess we will have to await independent testing. The Flex folks seem to assert they have the equivalent of more than 24 bit when dealing with adjacent strong signals. From the Flex reflector... Just in rough numbers, you get a 1/2-bit for every divide-by-two decimation you do. If you are looking at dynamic range in a 500Hz bandwidth (this is what we typically do). The math I generally use to get there is log(f1/f2)/log(2)/2. I just think this way as a programmer (do everything in base 2). So if you take log(245.76E6/500)/log(2)/2 you get 9.4 extra bits when added to the 16 gives you 25.5 bits (152.7dB dynamic range). This assumes all 16-bits of the ADC are good which is probably not a good assumption. I'd have to pull out the notes and look at the data sheet again, but this should give you a rough idea. Hopefully I haven't made an additional duh today myself! Bottom line -- there's plenty of dynamic range. Also, if you are interested, we are using Xilinx DSP48E1 blocks which use an 18x25 multiplier and so Xilinx tools generate the on-board DDS as a 25-bit DDS by default --- again to preserve the SFDR of the receiver. We could add extra bits, but 25 are fine for the same reason.

Re: [Elecraft] OT: Dayton New Equipment Show
Direct digital conversion radio receivers rarely connect the A/D directly to the antenna input, the term direct referring to a lack of analog frequency conversion (mixing). The Flex 6000 series is no exception to this trend. There is a gain and filter stage ahead of the A/D, and presumably an AGC. This is how dynamic range is managed on this, and many similar receivers. Blocking is a concern, but not even the greatest concern. Analog signal levels should, regardless of the number of discrete measurement steps (bits), should be kept well above the minimum input level to avoid excessive quantization error levels.

Actually it depends on one's assumption of the number and strength of the signals applied to the front end. 120 dB of spurious free dynamic range is trivial if one is measuring it with *two tones*.

Instantaneous peak voltages do not add linearly ... they add exponentially. Even with decimation the peak voltage to the ADC can not be allowed to cause an overflow.

Joe, W4TV On 5/19/2012 8:08 PM, wb4...@knology.net wrote: Joe, I'm not sure some of your suppositions are correct. First of all, the ADC samples at a significantly higher rate than the incoming RF (for HF), at 245.76MHz. Then, those samples go through decimation inside Digital DownConverter (DDC) in the FPGA, and the higher the decimation, the more the processing gain, and therefore added bits. I believe the typical assumption is that you gain the equivalent of approx. one-half bit (3dB) of dynamic range every time you decimate (divide) the sample rate by two. This is real gain, not some imaginary trick or magic. If you start with a 245.76MHz sample rate, and end up with 240kHz (example), you could achieve a processing gain of an additional five bits, or 30dB. If my quick math is correct. All without AGC or other games. Throw away at least one A/D bit, so 15 bits(ADC) plus five bits(proc gain) yields 20 bits, or about 120dB of dynamic range. I must be a little off, as I saw one note on the Flex reflector that they think 153dB or so of dynamic range. Maybe by lowering the final sample rate some more, or not tossing all of one bit of the ADC. I believe Mitola suggested that 130dB of dynamic range is adequate for HF, I'm not sure if that includes noise from storms, etc. BTW, the new software is called SmartSDR. I have been playing with DDC receivers for a couple of years now, and I firmly believe they will be the future. I suggest that thorough research of DDC-based receiver design will alter your perception. It did mine. I love my K3/P3, and do not plan to replace it anytime soon. It just works GREAT, and is a nice compact box without requiring a computer to use. But, I was very tempted to by a Flex 6500. That is, until I saw the $200 per year charge for the software. Technically, very leading edge. Marketing, you decide. Hope this isn't too off-topic. 73, Terry, WB4JFI -Original Message- From: Joe Subich, W4TV Sent: Saturday, May 19, 2012 7:29 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] OT: Dayton New Equipment Show The Flex 6000/6700 is an on frequency direct digital conversion radio - that is a 16 bit analog to digital converter operating at the front end of the radio with no intermediate conversion/IF and filtering stages. In addition, all of the DSP is contained in the radio (no more PowerSRD). The new software for the Flex 6000/6700 (reportedly PowerRX) is essentially a glass control panel). A general purpose computer is required for PowerRX but communication between the computer and transceiver is via TCP/IP which means the computer can be anywhere. Audio input and output will be available both on the transceiver and from PowerRX (interesting for remote operation scenarios). The issue will be the severely limited dynamic range of the 16 bit ADC. Without effective AGC ahead of the ADC there *will* be overload problems on crowded bands (e.g. 160/80/40) where any transceiver must deal with many extremely strong (local) signals while maintaining maximum sensitivity. With AGC, the strong local signals will cause blocking as the gain is reduced to prevent overflow of the ADC.

Re: [Elecraft] OT: Dayton New Equipment Show
Guess we will have to await independent testing. The Flex folks seem to assert they have the equivalent of more than 24 bit when dealing with adjacent strong signals. Yes we will need to wait for independent testing but given relatively wide filters (200 KHz or more), that testing can't be done with only two signals. The tests will need to be (notched) noise power tests or multiple tone tests that stress the *total* power handling capability of the system. It is the huge increase in instantaneous peak voltage when multiple signals are present that causes multi-channel (multiplexed) power amplifiers to be rated for peak powers as much as 20 dB higher that their average operating (output) power. The same problem of peak to average power (voltage) *will* impact the absolute voltage handling requirements of the ADC used in any DDC system. Decimation may improve resolution but not the absolute maximum and minimum signal levels. 73, ...

The Flex folks seem to assert they have the equivalent of more than 24 bit when dealing with adjacent strong signals. From the Flex reflector... Just in rough numbers, you get a 1/2-bit for every divide-by-two decimation you do. If you are looking at dynamic range in a 500Hz bandwidth (this is what we typically do). The math I generally use to get there is log(f1/f2)/log(2)/2. I just think this way as a programmer (do everything in base 2). So if you take log(245.76E6/500)/log(2)/2 you get 9.4 extra bits when added to the 16 gives you 25.5 bits (152.7dB dynamic range). This assumes all 16-bits of the ADC are good which is probably not a good assumption. I'd have to pull out the notes and look at the data sheet again, but this should give you a rough idea. Hopefully I haven't made an additional duh today myself! Bottom line -- there's plenty of dynamic range. Also, if you are interested, we are using Xilinx DSP48E1 blocks which use an 18x25 multiplier and so Xilinx tools generate the on-board DDS as a 25-bit DDS by default --- again to preserve the SFDR of the receiver. We could add extra bits, but 25 are fine for the same reason.

Looks like Alaska is sending me another storm when I should be getting them from Hawaii. Guess the seasonal winds have not yet stabilized. Propagation was up and down all week but it ended on a high note. Hopefully tomorrow conditions will be like they were Friday. A CME is to give us a glancing blow but may have missed. I have not read Space Weather today. Getting outside and enjoying the last of the sun for a week and cutting a little wood was more important. By the way, does anyone know of a good PC board shop where I can get a few 4 layer prototype boards which won't cost an arm and a leg? I find $540 for three boards a bit too expensive.
