What's the trick to getting LP_Bridge to run with Windows Vista?? I can get it to run and connect to the K3, but I can't get it to create the virtual comm Port for HRD. "Cannot create virtual port".

What is the voltage off-load when it is set like that? But the K3 power switch is a "soft" switch isn't it, so some electronics are still connected to the supply even when the switch is off? Mine consumes 30VA even when no load is present, so for the sake of the environment everything here now gets switched off at the mains when not in use. The supply cable for the K3 certainly uses less copper than the ones supplied with JA radios. The PowerPole connectors seem a bit wimpy to me as well.

This sounds similar to what I was noting on PSK31 when I experimented with higher power levels. However someone else commented the figures I gave were surprisingly high, so I did some more tests and found that on 20m I am getting -34dB PSK IMD right up to 100W output! However the poorer figures which I measured on 30m are repeatable. I'm not sure what to make of this and I am using an amateur PSK meter not a lab grade spectrum analyzer so at this point I am not sure if I can believe the measurements. I am going to see if I can substantiate the results receiving off-air using another receiver and computer. But your comments, my results (and the Eham review causing so much concern in some quarters, which mentioned SSB splatter on 17m) could indicate that there is a variation in PA linearity from band to band that might make some rigs clean on some bands and not on others. Why might this be? I wish there would be a "service manual" available, like there is for any Japanese rice box. I mean a manual that contains all data for all adjustments. Why not?? It should not really be difficult. After all the K2 was designed to be built from scratch by people with nothing more in the way of test equipment than a DVM and a dummy load. Probably the only adjustable setting is the bias voltage, though I haven't looked at the schematic since it isn't something I personally wish to tinker with.

But why not just use heavier cable if that's an issue instead of just sticking with the default that came in the box with the K3? Cable size should be tailored to length anyway, based on standard copper resistance tables and current draw. I really don't know why Elecraft even bothers to supply a cable, except for something to use as a "quickie" to get power to the radio for testing.

I found while assembling my K3 that the crimp connectors that go on the circuit breaker were not crimped well. They pulled out very easily. I replaced them. I go from 14.3 to 13.7 on the front panel voltmeter display at full power out. I see no worse than -31db 3rd imd on my old HP analyzer. It hasn't been cal'd in a while but my other rigs are about the same except my old Ts-830. Of course it's better. I love that rig. But I can't seem to get the cat interface to work.

Adam, I run Vista Home Edition here and it works fine but in the beginning
it would not create virtual com ports. I am not sure what I did to make it work but I think it may have been something so simple as to right click the LP Bridge Icon and click run as administrator. I have also created an Administrator sign on and sometimes have to sign on as an Administrator to install programs as an administrator. 73 de KE4WY Jim -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Adam Koczarski Sent: Tuesday, January 27, 2009 2:51 AM To: [hidden email] Subject: [Elecraft] LP_Bridge and Windows Vista What's the trick to getting LP_Bridge to run with Windows Vista??

Finally got it to work later last night. I had already tried the 'run as admin' without success. I had just upgraded this system from XP to Vista, then to Vista SP-1. Doing a reinstallation of LP_Bridge did the trick. Must be a driver permission thing that doesn't make it through the upgrade process. The LP-Pan and the associated software works as designed, as does HRD. I've been experimenting with Windows 7 on another laptop here and thought it would be <fun> to try and test out the K3 tools on that OS. You can only upgrade to Windows 7 from Vista at this point in the BETA, thus last night's upgrade from XP to VISTA on the radio laptop. I'll give Windows 7 a shot tonight and see what happens. Anyone try this yet? With my week of experience with Windows 7 it seeming to be more like Vista SP-2 than a new product. That would explain the amazing stability reports for a Microsoft BETA OS. :) Seems like more of a marketing "rebranding" of Vista than a newly developed OS. I guess the Bill Gates-Jerry Seinfeld commercials just weren't doing the trick. ;) It is much faster/leaner feeling than Vista, with a few GUI changes and it comes bundled with IE 8 BETA. The IE 8 BETA definitely feels like a BETA. Some tests I've read even claim it's faster than XP! I'll keep my fingers crossed and report back what I find.

> Is there something critical in the radio that > gives this outcome? Critical adjustment perhaps? > Is it very sensitive what PS we use (ala W4ZV)? Yes, it is very sensitive to power supply voltage. Look at any of the application notes - the one Craig mentions for the P-P RD100HHF FETs is a good example. Decreasing Vcc (or Vdd) by just one Volt will increase the IMD at 100 Watts by 10 dB and decrease the maximum output power by almost 20 Watts. Running the power supply at 14.0 - 14.5 Volts and using a power supply with good dynamic regulation will go a long way to keeping the K3 "clean." 73, ...

This is possible, but, as far as I know, it is untested. I've read
several anecdotes claiming poor SSB performance, and several others claiming excellent SSB performance. What's needed is for someone to take one of the "poor" K3's, and change some factor that turns it into an "excellent" K3. Such as, plug it into a better power supply, and show that one power supply consistently produces good results and another consistently produces bad results. I predict that the power supply claim will turn out to be bogus. The K2 has voltage regulators all through it, and runs well down to -- is it 10 volts? The K3 needs a bit more oomph, but I'll bet Wayne designed it to be robust, too. I further predict that the bad SSB performance will turn out to be either an adjustment issue, or an external amplifier issue. I'd love to see some experiments.

Before making statements like that please look at the K3 schematics. Power for the KPA3 is taken from the power supply input immediately after the RF choke, to J67B/P67B, through R3 (the current sense resistor for the metering), to J78B/P68B and to the final amplifier transistors via an RF filter. There is absolutely no regulation of the Vcc applied to the push-pull 2SC2782 pair used in the KPA3. I can guarantee that running the KPA3 will result in low power output (80 watts?) with significant IMD at that level. 73, ...

I haven't tried this myself but have seen somebody else do it. Does
anyone know if it is possible to send CW from say a laptop and to be transmitted as RTTY...... Couple of weeks ago I was on vacation in EA8 and ran my microham unit with a laptop running win-test in expedition mode into my K3. I would liked to have worked the TS7C who were loud with me on rtty, after all I could copy them on the LCD readout of the K3. I did not have a paddle with me but sent CW from the laptop keyboard. I tried to get it to send RTTY but only got a tone........ I assume if one is using the internal keyer of the K3 you may only input CW via a paddle?

My program KComm can also send PSK31 and RTTY (and CW) from the keyboard using the same method.

I don't know if it works in DXpedition mode, but it'd be worth a try... ~Iain _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The K3 has a transient suppressor that should blow the fuse if a big enough transient appears on the power connector. Looking at the RF board schematic I see a BZW50-15 overvoltage protection diode connected between ground and +12V on the radio side of the fuse. I downloaded the data sheet for that part - it looks like the breakdown voltage is 16.6V minimum at 1 mA. The actual clamp voltage is a complicated function of peak current and pulse width, but presumably Elecraft chose a part that adequately protects the radio.
