I did have a conversation last year with 4O3A, designer of the Power Genius. From what Ranko said, the Flex amp seemed to have more headroom than the KPA1500, which might result in better linearity at 1.5 kW, albeit at the expense of efficiency. (The specs say "capable of 2 kW.") There is some scheme to dynamically adjust the supply voltage for higher efficiency at lower power, I presume for CW and RTTY, where linearity isn't a big issue. I read somewhere that supply voltage is NOT modulated in SSB mode, which I imagine would cause lots of nonlinearity. The Flex amp can do predistortion with their radios. However, the KPA1500 also has an output sampling port, which should allow it to do predistortion also with a radio capable of it, probably including the Flex. (I wouldn't be surprised if Elecraft came out with that feature eventually. Could that be the reason it has that sampling port?) The Flex amp has an external ATU, which 4O3A strongly favors, but I think that's a personal preference. For most stations, with antennas that aren't always below 1.5:1, a solid state amplifier without an ATU is pretty useless, so I think Elecraft's decision to integrate it makes sense. While the Flex amp can certainly be made to work with Elecraft radios, the seamless integration with the KPA1500 is very attractive. I'm happy with mine so far. 73, Scott K9MA -- Scott K9MA k...@sdellington.us __ 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] Amp comparisons
After much investigation and consideration I elected to purchase the KPA-500/F. Since I have the K3S and now the KAT-500, I've "trained" the KAT-500 for the antennas and frequencies on each band. With the VFO tracking, I dial the frequency and everything follows. Specifically the KPA-500 I find to be very quiet, it delivers 500 watts + on every band, 160 - 6M. Drive power is about 25 watts on every band. The fan is quiet and is of no concern even at the highest speed. It does step down quickly as the amp cools. Normally the fan is off until the temperature rises. Using it on FT-8 at 500 watts out, it will increment to #2 on occasion. The input always appears as a 1:1 SWR to the transceiver. The high SWR circuit does protect the amp and is fast. With my station configuration I feel as though I have a 500 watt transceiver, automatically selecting antennas and tuning as needed. I touch nothing but the VFO knob or enter the frequency for the next band. Everything switches silently and automatically. I come from a line of tube amps in the 1000 to 1200 watt class. Fans run all the time. Power output varies with band as well as drive requirements. Most seem to be optimized for 20M. My last tube amp was a AL-80B and it was one of the smoothest tuning amps I've used. Power out always 1000 + watts. But it required tuning with each frequency and band change. The difference in power is 3 dB or only 1/2 S unit. All works for me. I vote for the KPA-500. 73 Bob, K4TAX On 7/23/2018 8:22 PM, Rick Reynolds wrote: I'm looking at upgrading my amp.

Re: [Elecraft] Amp comparisons
I ran my 1;2 KW amp at 500 watts for close to a year before springing
for the KPA500 just to see if it made any difference. It probably would
have were I an avid DX'er or contester. At my casual level, I really
noticed no difference. With a K3 I think the algorithm is:
if(I_want_full_power) {get_KPA1500}
if(I_want_to_save_a_few_bucks) {get KPA500}
The integration of either with the K3 is absolutely seamless. I have no
experience with the KPA1500 but the KPA500 was bulletproof, or so it
seemed. I also had the KAT500 which made a very compact moderate power
station.
This is past tense, we moved to an HOA community and 500 watts into my
end-fed WOOF antenna [Wire On Organic Fence] didn't seem like a good idea.

Re: [Elecraft] Amp comparisons
I had a SPE 1.5K for a couple of weeks. It struggles to make 1.5KW on all bands and on some doesn't make it. At 1.5KW there is around 2dB compression. It's great up to 1KW. I've had the KPA1500 for about a month now. It makes 1.5KW with between a .5 and 1dB on all bands. It's more money than the SPE, but worth it. And of course excellent support from Elecraft.

Re: [Elecraft] Vanity call question
(sorry for the previous blank email -- I keep forgetting that this mailing list strips out HTML-format text) I was originally licensed in 1970 as a Novice in Murfreesboro, TN as WN4SBE, which changed to WB4SBE when I upgraded to Advanced the following year. I kept WB4SBE for 30+ years, even after moving to Ann Arbor, MI in 1982. I finally got off my keyster and passed my 20 WPM Extra in the early 2000's, just before the FCC lowered the code requirement to 5 WPM for all license classes, and eventually doing away with it altogether. Armed with my newly-minted Extra, I figured it was high time to look into a vanity call. For one thing, I had been plagued in certain contests with folks guessing my section as "Virginia?" because of the 4 in the call sign. Don't know why "Michigan" sounds so much like "Virginia", but I figured that changing to an 8 would fix that. I toyed with going with something like my initials (DN or DEN), but I shied away from DN since that is too easily mistaken for "/", and I think DEN was taken in all the short suffixes (W8, K8, N8) at the time. So, I found that N8SBE was available, and I figured the 'locals' would know who I was, based on just changing the prefix. Anyway, "Side Band Engineer" has a nice ring to it (as does "Subacute Bacterial Endocarditis", a throat infection, as related to me by a doctor on 20m phone one day), although I've found that on phone contests, "Sierra" is frequently mistaken for "Kilo", and has resulted in busted QSO's (and even more annoying, N8KBE is now found in the super partial check database, even though that station has not been active in the contests). I've tried using "Sugar Bravo Echo" and had Spanish-speaking stations correct me back to "Sierra Bravo Echo", so I guess you just can't win. On CW, N8SBE has a really nice swing to it, with mostly alternating dahs and dits in groups, helping to separate the characters. What's really funny though, is that the "BE" on the end is the same as the old 'knock/knock" that a a lot of old timers ended QSO's with, and I've actually had folks respond to my callsign with "dit dit". I don't know if they are just letting me know that the frequency is busy, or if they are just playing along with the joke. All I know is that I've had a lot of fun on ham radio over the years (coming up on 50 in 2020), and moving up to Elecraft (first a K3/P3 in 2009, and now K3s/P3 and KX2) has really enhanced my enjoyment of the hobby. Seems I'm discovering something new every day. I made FT8 contacts for the first time recently, using DXpedition mode with the KH1 folks, and it was really nice knowing that they had just as nice of radios on their end as mine.

Re: [Elecraft] OT: WSPR SNR to CW real world conversion
What is the referenced bandwidth for the noise? 3 KHz? And what if I narrow the filter bandwith to just the occupied bandwidth of each signal? With fldigi when I have filter narrowed the measured snr goes to 30 dB. So the snr algorithm is very sensitive to filter width. Have not looked in the code to try to figure out if the snr measurements are comparing the signal to adjacent empty FFT buckets. 73, tom w7sua On 7/20/2018 10:49 AM, Allan Zadiraka wrote: I don't recall where this table of Relative Sensitivity of Communication Modes came from but for what's it worth:: Mode Signal to Noise Ratio Threshold WSPR -27 dB JT65 -24 dB FT8 -20 dB Olivia -17 dB PSK31 -7 dB CW -1 dB RTTY +5 dB SSB +10 dB *Allan Zadiraka* *AB8OU* 4110 State RdAkron, OH 44319Work: 234-738-4578Cell: 330.760.4569Home: 330.644.1839 On Fri, Jul 20, 2018 at 1:03 PM George Pasek wrote: I have used WSPR through the past years and have always been amazed at how far one can go on so little power.

Re: [Elecraft] KAT500 Bypassed or Bypass?
A relay click is provided as audible confirmation of the MODE button press. We also don't want any Mode changes while the amplifier is providing QRO power. The amplifier key interrupt relay is set to "amp not keyed" by any mode change, a short delay, check for too much power, then the ATU settings are changed if needed (and in your case probably wasn't changed) and then the amplifier key interrupt relay is released. You hear this pull and release as a click. The amplifier key interrupt relay is switched to inhibit the amplifier's key line before any RF path ATU relay changes to avoid hot switching relays at high power. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of ANDY DURBIN Sent: Monday, July 23, 2018 08:43 To: elecraft@mailman.qth.net Subject: [Elecraft] KAT500 Bypassed or Bypass?

Re: [Elecraft] SVGA for P3 - only looking for ten (10) replies (is that possible?)
Thanks to all who replied very informative and congratulations to the rest for holding back we only had seven (7) replies so not overwhelming :-) To summarize the replies: Although the SVGA addition is very nice it is not absolutely necessary as the P3 as it is provides adequate resolution in its smaller (8”?) display. However the benefits of the SVGA option include: Better “view” into the spectrum when operating Split/chasing DX With the better resolution comes the ability to “see” smaller signals and pull them out of the noise With the larger display there is more physical area to see things including longer timeline of the waterfall (two minutes?) Easier to see if eyesight is diminished/diminishing for us older folks Quicker to glance over and see the important stuff as it is larger The built-in FFT processor provides much better resolution (4x?) and 1080p (1920x1080) Larger decode window for PSK/CW modes So the consensus is that the option is worth the cost if you have room for the monitor (which really can be anywhere from 20” up) however the P3 stands on its own quite nicely. My P3 arrives today sans SVGA option so I’m going to use it for a while “barefoot” (Hi Hi) before I decide to add in the SVGA. 73 Michael KK6RWK > On Jul 23, 2018, at 7:27 AM, Bill Frantz wrote: > > And if you are using PSK or CW decoding, the SVGA gives you a much larger > decode window and so more time to read what is being decoded. > > 73 Bill AE6JV > > On 7/22/18 at 8:17 PM, j...@audiosystemsgroup.com (Jim Brown) wrote: > >> On 7/22/2018 7:27 PM, Randy Farmer wrote: >>> If you're doing split frequency DX chasing or Search & Pounce in contests, >>> the big screen is a VERY valuable resource.

Re: [Elecraft] About a two-phase install of the KSB2 option on a modern K2
Mark, You can do any and all of the KSB2 installation and still transmit and receive CW as before. If you remove W2 and W3, you can restore receive by placing a bent wire jumper from pin 1 and pin 3 of both J9 and J10. Similarly, transmit can be made operational by installing a .001 capacitor between pins 7 and 12 of J11 (or you can leave C167 installed until the last minute before the KSB2 is installed). 73, Don W3FPR On 7/23/2018 9:56 AM, Mark Petrovic wrote: I have a couple days of available bench time this week before I go on vacation.

[Elecraft] Announcing "The Serial Box" serial port-splitter and amplifier interface
Product Announcement My new "Serial Box" (S-BOX) is a passive serial port Y-splitter and amplifier interface box. It does for 9-pin serial ports what my Y-BOX does for the K3 15-pin ACC port, and more. The S-BOX can provide automatic band changing and frequency tracking from any modern transceiver to any Elecraft, ACOM, or SPE automatic amplifier (if supported by their CAT or CI-V monitor). It also works with the SteppIR control boxes, the SDR-IQ, and other devices designed to "listen in" on serial port traffic between a computer and a transceiver. By default, only the RS-232 RXD and GND lines of the secondary serial ports are wired in parallel to the pass-through port, so there's little potential for RS-232 communications conflicts. Details, photos, examples, schematics and an order form link may be found here: https://bit.ly/S-BOX Each S-BOX can be custom wired and labeled to match your specific hardware interface requirements. But, the S-BOX is also flexible enough to be easily rewired in the field, as needed, when your hardware changes, with no need to obtain new custom interface cables. *For K3/K3S owners*, the S-BOX can provide one or two independent FSK RTTY + PTT keying interfaces, or an easy interface to an SPE or ACOM amp. with automatic frequency tracking, without requiring any custom-made interface cables. It can also be used to remotely "power on" a K3 or K3S, with no Remote Rig box required. *For KX2 and KX3 owners*, it can be used like a "Docking Station," providing computer-generated CW keying over the DTR pin of the same serial cable that is being used to control the radio, using only economical TRS-to-RCA stereo cables and a standard serial cable or a USB-to-Serial adapter, no WinKey required. The S-BOX also makes it easy to connect the KX2 or KX3 to an automatic linear amplifier without the need for any custom-made or home-brew cables. *For KPA500 and KPA1500 owners*, the S-BOX makes it easy to connect the XCVR or PC DATA connectors to the KX2 or KX3, or to non-Elecraft transceivers (Kenwood, Icom, FlexRadio), for automatic band changes and tuning, without having to rely on the "RF sense" feature. No hand-built "Cross-Over-Serial" cables required. The S-BOX can also be used to remotely and independently "power on" or "power off" a KPA500 or KPA1500, with no Remote Rig box required. The S-BOX includes four internal NPN open-collector keying circuits (CW, PTT, FSK), optionally keyed via any of the serial port TXD, DTR, or RTS pins using logging software, so you can key CW over the rig's serial cable, even if the radio doesn't support that feature (e.g. KX2, KX3,TS-590S, IC-7700, IC-7800). One can also key CW or FSK RTTY via a separate serial port, or key two different radios independently, using one or two serial ports and a single S-BOX. FYI, my other product, the Y-BOX, is still in production, and is especially useful to owners of the K3/K3S, KAT500/KPA500, or KPA1500 and SteppIR (see https://bit.ly/Y-BOX). The S-BOX can optionally be "daisy chained" to the Y-BOX, via a standard M/M DE-15 cable, or connected using RCA patch cables. Connecting the two is mostly useful if you need FSK/PTT serial keying or the K3 Remote Power ON feature.
