Re: [Elecraft] K3 and transverters
I used mine at home and more often on mountain tops during VHF+ contests as a rover. I am often in line of sight to other high power rovers and the KW stations in the valleys below. I used a K2 with my transverters. After a number of previous rover setups that did not do well, I found this combo worked well. I had no more adjacent bleed issues, and stability was quite acceptable. I have since swapped the K2 for the K3 just because :-) . I have not had the K3 combo out on a mountain top yet. I have done extensive A/B swapping at the home station between the XV144 and K144XV and show no discernable difference in performance except some noise/spur pickup and lower output power in the K144XV (no surprise). That is offset by having the 4Mhz band coverage making FM possible. I like that since I an pickup Simplex QSOs and do some occasional repeater or satellite work and use the same antennas, no extra switching or rotators required. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-and-transverters-tp7562743p7562802.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

Re: [Elecraft] K3 and transverters
Jim, mountains around DC ??? I used to live in Barnsville, MD overlooking Sugarloaf Mountain, and that is about as close to mountains around DC as it gets. I cannot recall the height of Sugarloaf Mountain, but it was not that great, and it was private property when I was there in the 1980s - but the owners provided a path to the summit for visitors. It was often referred to as a bump out of place. One must go quite a ways Northwestward from DC to encounter mountains. Western Maryland yes, Southern Pennsylvania, yes, but much of Maryland is the eastern coastal. plains was flat and without bumps- yes those Eastern coastal plains do turn quickly into mountains, so your choice of position is a big factor in your assessment of vertical altitude. If one wants mountains when in Maryland, it is advised to head for Western Virginia and the Shenandoah Mountain range. Southwest of Maryland is the great Shenandoah National Park where My family vacationed for many years. My children grew up on the instructions from the park rangers at Big Meadows. 73, Don W3FPR 9/16/2012 2:06 AM, Jim Brown wrote: On 9/15/2012 10:43 PM, Vic Goncharsky wrote: What I am personally looking for is information about on the air performance of 144 and 432 Elecraft transverters in strong signal environments like VHF/UHF contests in dense areas with multi-kilowatt folks occupying mountain tops all around.

[Elecraft] K3: Use of KX3 USB/RS232 cable
I have been trying to use the KX3 USB/RS232 cable to command my K3 via its RS232 port. I assumed that this would require only the RXD and TXD connections that is supported by the KX3 cable. But it will not establish contact with the K3. I have a conversion box with a stereo 3.5mm mini-phone connector connected to a DB9 for making the connection with the K3. Tip --pin-2 (DB9) and Ring -- pin-3 (DB9); Gnd -- pin-5 (DB9). My K3 Prolific USB/RS232 cable makes contact with the K3 with no issues. The KX3 cable is connected via com-3 while the K3 cable is connected via com-5. Looking at these ports on the device manager the appropriate drivers are installed for each port and indicate they are working. Com-3 connects to the KX3 fine and com-5 connects with the K3 fine (using the appropriate utility sw). Just wondering if there is something incompatible between these two serial cables that they cannot be used with the other radio? The reason for asking is that I need both com ports to support operation from two programs that need to communicate simultaneously with the K3. One sw is only requires RTS or DTR to control PTT, while the other sw is using RXD and TXD to execute a frequency command. Both programs operate correctly with the K3 if I use the K3 serial cable to connect them. 73, Ed - KL7UW __ 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

Yes, Simon, you will likely find that the sloping signals drifting across the waterfall are caused by local switched mode PSUs. Perhaps your own?

Re: [Elecraft] K3 and transverters
It's possible that I was among the first, if not the first, to report the K144XV self-oscillation problem in March 2010 not long after it started shipping. It took six months to solve, including 3 replacements units, a replacement KXV3A and a lot of emails, tests and effort on both sides of the Atlantic. David G4DMP whose K144XV showed the same problem eventually isolated it. As he has said in an earlier posting, the solution, discovered in September 2010, was simple in the end. It is implemented in K144XVs shipped since then and referred to in an Errata Sheet for the K144XV Installation Manual dated September 30th 2010. It applies to pages 15 and 16 of the Manual and involves the omission of one of the screws holding the top cover. I believe the metal standoff beneath the hole may also be omitted now but is still shown in the photograph on page 14 of the Manual, the date of which precedes the solution. In the unlikely event of anyone out there still having the problem, the above details may help. As will be apparent the support from Elecraft was unstinting and the K144XV may now be bought with full confidence. I would agree, however, that the K144RFLK is essential, for CW and SSB operation operation at least. I have never had problems with strong local signals but here the 2m band is so rarely awash with them that it's not surprising. 73 to all Geoff G3UCK -Original Message- From: Ron D'Eau Claire Sent: Sunday, September 16, 2012 12:02 AM It's my understanding that the oscillation problem was solved long ago by (IIRC) a change in the K144XV pc board ground scheme. __ 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

[Elecraft] K3 PLL 1 problem
Today I started having a PLL 1 problem. I even saw an ERR PL1 show (only) one time I first noticed it when on 160m. I was on A=1.900 and B=1.895 then I went into Sub. I can switch from VFO A to B back and forth and all is ok I turn the Sub on With VFO A on 1.900 VFO B on 1.895 then if I switch A/B the 1st time works then the next time (when I switch back B/A) PLL 1 = *00 It doesn't matter which VFO (A or B) is on 1.900 and which is on 1.895 the failure is always on the 1.895 frequency. If I move VFO A knob the PLL will resync. With Sub on or off If I pick any other combination of 160m frequencies separated by 5khz or separated by any amount, or even on the same frequencies. A/B B/A works just fine PLL 1 doesn't lose its sync and give me *00 It works as it should when Sub is *NOT* on! It only fails when Sub is on and only with the 1.900 1.895 combination. This was working on previously. Today is the 1st time it has failed. I have rerun the synthesizer calibration on both PLL 1 2 === when VFO A is tuned to 1.900 PLL 1 = 3.4 when VFO A is tuned to 1.895 PLL 1 = 3.3 when VFO B is tuned to 1.900 PLL 2 = 2.2 when VFO B is tuned to 1.895 PLL 2 = 2.2 === === PLL 1 varies with turning the dial from as low as 1.6, up to 5.8 PLL 2 doesn't ever seem to vary from 2.2 then again I can't turn VFO B and watch it as I turn but even if I turn VFO B around and then check PLL 2 PLL 2 is always 2.2 when I check it. === any ideas, comments? -- GB 73 K5OAI Sam Morgan __ 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] Question about suspending a delta loop...
Rick, Is your delta loop suspended with its apex up or down, or is it a horizontal loop? If the apex is down or up it is better to use only one counterweight, otherwise the antenna will walk if the trees sway in the wind. A supporting catenary will also walk if a counterweight is used at each end. At my last QTH in GM all of my HF wire antennas were supported by tall pines and exposed to very high winds. So I might be able to offer some suggestions if you could please tell me about the configuration of your loop. 73, Geoff LX2AO On September 16, 2012 at 4:37 AM, Rick McClelland, AA5S wrote: I have a 240' delta loop suspended at three points about my QTH. I've been pondering adding another 47' but this is quite a challenge given the dimensions of my suburban lot. One thing I'm considering is to make good use of two trees located in a common area outside my property lines. Easily said, but I would not want to hang a 5 kg line ballast at either of these points because I can imagine a couple of neighborhood youths scaling a tree with one of them cutting a line causing the 5kg weight to crash down upon the tender skull of the other youth. Legal matters notwithstanding, my question is whether I'm inviting certain mechanical failure if I fix the two endpoints outside my property lines and make use of only a single 5 kg ballast on the tree located within my property lines. The advantage of doing this is obvious, if any of the supporting lines outside my property are cut, the antenna falls onto my property and there is no possibility of injury to the purpetrators of the dastardly deed. As a possibly relevant aside, I don't use a typical insulator at each of the three suspension points. I use a 4 flat acrylic insulator with two 6 acrylic insulators attached to the end of the 4 insulator such that the resulting insulating apparatus appears to be a rather large 8 tuning rod. In my non-mechanical-engineering mind, I imagine that having the insulator arranged in such a fashion reduces the peak tension at each apex of the triangle and also allows the wire to move more freely through the insulator without binding at that point. I realize that this matter isn't related to any Elecraft product but there are so many sage OMs here that I feel that an answer will be quickly forthcoming and without controversy. -- Rick McClelland, AA5S Fort Collins, CO __ 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

It is routed over pulleys at the three corners, with the apex at a yardarm about 90 feet up a tower. The loop is roughly 75 feet per side, not a true delta shape. My antenna is fed to the radio using ladderline and operated multi-band through a 9:1 Guanella balun from 160M to 6M. It's buried in the woods. It's matched by the transmatch in my K3. I ignore the losses in the ladder line with CW. It is ordinarily fed as a loop at one corner although I am experimenting with what happens when one starts opening corners opposite to the feed point and feeding the antenna as some sort of irregular bipolar contraption. From the station I will soon be able to remotely reverse the feed points as well as open or close relays at will at the corners opposite to the feeds. EZNEC suggests that I have a tonne of impressive lobes and low angles on some bands. While the delta loop is off the best heading by virtue of limitations on where I could hang it, I will at least be able to reverse the antenna patterns and see what that does for me. Up here we get freezing rain and high winds and ice build-up all at the same time, and is always a threat to wire antennas. Therefore I hang all my antennas with bungee cords wherever the haul down ropes or other means of securing the antenna are located. To this, at the most accessible point of the antenna suspension system, I add a tie-wrap as the final means of securing the bungee cord (and hence the antenna) at ground level. I call this a frangible fuse, I termed I robbed from working in aerospace. A physics guy can explain it better, but really big forces build up in the antenna if it takes a sudden shock. Something about overcoming resting inertia made sense to me when I read about it. Ballast is not a good idea up here. We need something compliant like the bungee cords everywhere there is an opportunity to fit them. If the bungee cord goes to the limits of its travel, it breaks the tie-wrap, allowing the antenna to gracefully sag to the ground and rest until I pull it up again and replace the tie wrap. I want my antennas to fall down without damage so I have built a deliberate failure point in the system at minimum walking distance from the station. I have paid the price from having antennas destroyed by weather but this method is nearly fool-proof and it has frequently been tested. No antennas have been destroyed in this story. It doesn't matter what causes the sudden force on either of my wire antennas; if it is bad enough, it results in a graceful fall of the antenna wires to the trees below with its feedline intact and ready for quick return to service. 73, Gary VE1RGB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Rick McClelland, AA5S Sent: September 15, 2012 11:38 PM To: Elecraft Discussion List Subject: [Elecraft] Question about suspending a delta loop...

Geoffrey, I did leave out that important point. My delta loop is oriented horizontally, all three support points are at the same height (about 40') in three different trees.

If the apex is down or up it is better to use only one counterweight, otherwise the antenna will walk if the trees sway in the wind. A supporting catenary will also walk if a counterweight is used at each end. At my last QTH in GM all of my HF wire antennas were supported by tall pines and exposed to very high winds. So I might be able to offer some suggestions if you could please tell me about the configuration of your loop. 73, Geoff LX2AO On September 16, 2012 at 4:37 AM, Rick McClelland, AA5S wrote: I have a 240' delta loop suspended at three points about my QTH.

[Elecraft] KX3 #1690 observations
Hi All: I received my KX3 s/n 1690 about 10 days ago and have been putting it to work on many modes. It's got best receiver I've ever used, although the highest end xcvr I've owned previous to it was a TS850 with narrow filters - not quite high-end compared to the $5K radios on today's market. But I expected it to be good given Elecrafts work on the K3 - and I have been very pleased so far. I can see two areas where a tweak might be beneficial. With weak signals or QRN, I spend a lot of time using a CW passband of 150 or 100 Hz. It would be nice if the PBW control switched from 50 Hz steps to 10 or 20 Hz increments below 150-200 Hz - these would allow a finer adjust on close-in interferers while minimizing the need to go to 50 Hz passband with its higher PB center attenuation. The other area is maybe unique to HF digital mode operators. Since I'm QRP with the KX3, I use Olivia because of it's advantage as a weak-signal mode. With the KX3, I find that during a 3-5 minute transmission, the PA starts its HI-TEMP foldback at anything above the 3.0W setting. For this mode, the modest heatsink on the KX3 is insufficient - the plate is not terribly well thermally coupled to the devices - nor does it have much thermal mass. I could make something ugly with a piece of 3/16 in copper stock that I have using a 4-40 tap for threads - but I wonder if Elecraft could offer a heatsink upgrade for data mode users. I haven't tried heat sink compound on the FETs, but I still thing the heatsink could benefit from more thermal mass. Backpackers may not want the extra few ounces - so an option approach might work best. I wonder how other data users deal with this - a muffin fan would help I imagine. In summary, I am 90% delighted with the KX3. I cant wait for the amplifier to be announced - I really need the boots in my deed-restricted neighborhood. Is there a general timeframe this is expected to be announced / orders taken? I'd rather not get the Tentec 418 because the integration to the KX3 won't be as good and there's no internal tuner. Did manage to get NH8S on two bands QRP though...

Re: [Elecraft] FW: Question about suspending a delta loop...
Ahh, so it is more complicated that I previously thought. Splitting/rotting bungee cords would certainy make them unsuitable for this application. The phrase GEAR Resistance Shock Cord Assemblies is something I hadn't heard of until I started googling around following the suggestion of using bungee cords. I presume the fancy title indicates that they are more expensive than run of the mill bungee cords. These particular items are intended for use in the bungee jumping industry; as in, human beings jumping from great heights and being saved from certain doom by these items. If that is truly the case then maybe these have more durability than the Chinese made Harbor Freight variety. I guess someone has to try them out to see if they are suitable for this application, any bungee jumpers out there willing to give it a go and report back your results?

I've found some nice GEAR Resistance Shock Cord Assemblies on the Internet ( http://www.adrenalindreams.com/gallery14.html) that seem like suitable candidates.

Rick, I will describe what I have. Perhaps it will trigger something useful for you. I have a full-size 160M delta loop that is made from a single piece of that *Silky* jacketed wire which is wonderful around trees. It is routed over pulleys at the three corners, with the apex at a yardarm about 90 feet up a tower. The loop is roughly 75 feet per side, not a true delta shape. My antenna is fed to the radio using ladderline and operated multi-band through a 9:1 Guanella balun from 160M to 6M. It's buried in the woods. It's matched by the transmatch in my K3. I ignore the losses in the ladder line with CW. It is ordinarily fed as a loop at one corner although I am experimenting with what happens when one starts opening corners opposite to the feed point and feeding the antenna as some sort of irregular bipolar contraption. From the station I will soon be able to remotely reverse the feed points as well as open or close relays at will at the corners opposite to the feeds. EZNEC suggests that I have a tonne of impressive lobes and low angles on some bands. While the delta loop is off the best heading by virtue of limitations on where I could hang it, I will at least be able to reverse the antenna patterns and see what that does for me. Up here we get freezing rain and high winds and ice build-up all at the same time, and is always a threat to wire antennas. Therefore I hang all my antennas with bungee cords wherever the haul down ropes or other means of securing the antenna are located. To this, at the most accessible point of the antenna suspension system, I add a tie-wrap as the final means of securing the bungee cord (and hence the antenna) at ground level. I call this a frangible fuse, I termed I robbed from working in aerospace. A physics guy can explain it better, but really big forces build up in the antenna if it takes a sudden shock. Something about overcoming resting inertia made sense to me when I read about it. Ballast is not a good idea up here. We need something compliant like the bungee cords

Re: [Elecraft] KX3 #1690 observations
Stephen Rector wrote: The other area is maybe unique to HF digital mode operators. Since I'm QRP with the KX3, I use Olivia because of it's advantage as a weak-signal mode. With the KX3, I find that during a 3-5 minute transmission, the PA starts its HI-TEMP foldback at anything above the 3.0W setting Hi Steve, This is typical. The KX3's heat sink was designed to handle full power only for low to medium duty-cycle modes (CW and SSB) or for shorter transmissions. Olivia is probably worst-case, and I'd expect the maximum to be 3 W or even less. (At 3 watts, the KX3 automatically switches to a higher-impedance PA output, reducing current by about 50% relative to 3.2 watts.) We don't have a larger heatsink planned at this time; you're welcome to roll your own and/or apply some high-performance thermal compound. But there's one other thing you can try: reduce the supply voltage. With a supply voltage of say 9 to 10 volts, you should be able to operate key-down for much longer periods at 5 watts. 73, Wayne N6KR __ 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] (KX3) OMG My brand new KX3 has a nasty little problem!
Bruce, I had the same symptoms. In my case it was caused by a broken solder connection where the power jack attaches to the CP board. I removed the CP board, heated the connection and added solder to it. The problem is solved. The power jack is a surface mount device and as such had very little solder where it is connected to the board. If I were to build another KX3 kit I would resolder the power jack connections before assembly as a routine precaution. This appears to be a weak point in the KX3 construction. Lou W2ROW bruce whitney wrote The DC cable/connection is flaky.. any movement of the cord or twisting of the connector kills the power and of course when turning it back on again the radio comes back in default - many KHz away and in a different mode than the QSO - I wanted to throw it through the window!

Re: [Elecraft] FW: Question about suspending a delta loop...
I don't have a big loop, but I have not had any trouble with using a counterweight on my inverted L with one end supported at about the 40 foot level in a 60 tree. I use a compound pulley arrangement that halves the distance the counterweight must travel. About 30 lbs of counterweight supports my 100 foot antenna with about 15 lbs tension on the antenna wire. It has survived winds in the 60 to 100 mph range on dozens of occasions since I put it up in 2007. On one occasion the winds were strong enough to cause the counterweight to move about 10 feet, meaning the tree trunk was moving 20 feet about 2/3 of the way to the top. While shock loading resulting from sudden movement is a concern, my reasoning is that the wind must set many tons of tree in motion to start moving the counterweight, so the tree is a very robust shock absorber that prevents very sudden movements. The 5/16 Dacrom ropes I use have also survived nicely for 5 years without issue. As others have noted, the challenge when using a counterweight system is to keep the antenna from walking the counterweights to one limit. I opted to avoid hanging both ends of my inverted L in trees for just that reason. 73, Ron AC7AC __ 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] I/O output level
There will be some latency - so you have double latency - once through the KX3 and again through the panadapter software. That may or may not be troublesome. If so, the only cure is another soundcard and the cable to the headphone jack (and mic jack) You will likely want to use that 2nd sound card (one for the panadapter the other for digital modes), because the KX3 has no provision for transmit using the I/Q signals - to transmit, one needs to inject the tones into the microphone jack, so just accept that fact and add the path from the headphone jack to the soundcard as well. The listen through is nice because it does provide a 2nd receiver function for CW and SSB modes, and the frequency separation can be greater than the KX3 dual watch limitations. 73, Don W3FPR On 9/16/2012 5:25 PM, F5LCI wrote: Don, Thanks again for your help.

Re: [Elecraft] Question about suspending a delta loop...
Rick, Thank you for your reply, and my apology for taking so long to acknowledge it. I did at first try using bungee cords in GM land as Gary VE1RGB uses them, and for the reasons which Gary mentioned, but unfortunately the squirrels (mostly red) living on the farm there liked to chew bungee cords enough to render them useless. Thereafter I used UV resistant marine rope and Kevlar to support my antennas, neither of which squirrels like to chew it seems, together with fused counterweights. For the elements of my 40m wire beams and for my other antennas I used jacketed Flexweave, the jacketed type to protect the wire from the claws of the birds who perched on the antennas. If your antenna's wire can move through the supports which are not on your property without being damaged, a fused counterweight hanging near ground or a suitable bungee cord at the support on your property might be sufficient. Of course an antenna's support ropes should always pass through pulleys and not over branches, unless the antenna is a temporary installation. Marine pulleys (6mm) as used in small sailing boats have served me well. Any rope passing over a branch to support a pulley should be wiggled every eight or nine months to prevent the tree from growing over the rope, which would make it difficult/ impossible to move the rope later on. If you cannot find suitable bungee cord and are interested in knowing more about the fused counterweights which I used, please let me know. 73, Geoff LX2AO On September 16, 2012 at 6:07 PM, Rick McClelland, AA5S wrote: Geoffrey, I did leave out that important point.

Thanks Don, After trying to compare these two audio signals, I have arrived at this conclusion, valid for /my setup/ (e.g. noise from the laptop screen (look at my page on QRZCQ): IMHO the I/Q derived audio by the PC can be of some utility, but the KX3 does it better. SDR receivers (I own a PMSDR) are pleasant, but the IF to audio stages are another story : KX3 rules... 72 de FO/F5LCI Don Wilhelm-4 wrote There will be some latency - so you have double latency - once through the KX3 and again through the panadapter software. That may or may not be troublesome. If so, the only cure is another soundcard and the cable to the headphone jack (and mic jack) You will likely want to use that 2nd sound card (one for the panadapter the other for digital modes), because the KX3 has no provision for transmit using the I/Q signals - to transmit, one needs to inject the tones into the microphone jack, so just accept that fact and add the path from the headphone jack to the soundcard as well. The listen through is nice because it does provide a 2nd receiver function for CW and SSB modes, and the frequency separation can be greater than the KX3 dual watch limitations. 73, Don W3FPR -- View this message in context: http://elecraft.365791.n2.nabble.com/I-O-output-level-tp7562551p7562853.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
Re: [Elecraft] Power supply for incoming KX3
Mike, Usually, I recommend a 6 amp power source for a transceiver that is rated for the range of 10 to 20 watts, your power supply will do fine at the 5 watt level. It even may do 10 watts with no problem, but I try to rate things conservatively. My politics may be liberal, but the electrons get a conservative consideration. Hey, it's an election year and I have not yet made up my mind :-) 73, Don W3FPR On 9/16/2012 9:14 PM, Mike Weir wrote: I have a small desktop regulated power supply rated at 13.5 volts DC nominal, 3.0 amps max continuous, 5.0 amps max. Can I use this to run the KX3 while it's desktop? The max output will on the KX3 will be 5 watts QRP.

Re: [Elecraft] [K3] [P3] IF Out / IF In Cable
Yes, the cable impedance does not matter but the connectors do. The 75-ohm cable probably has 75-ohm BNC plugs, which as I recall have a smaller pin. They might not make reliable connections with the 50-ohm sockets on the K3 and P3. Go ahead and try it, but if the connections seem flakey you should get a real 50-ohm cable.

Alan N1AL Possibly, but unlikely. I've got a bunch of 75 ohm cables with BNCs on both ends that came from a broadcast studio when they rewired it (either ABC Chicago or PBS Chicago, if I recall correctly)) and they all mate just fine with my 50 ohm females. Indeed, the only BNC cable I've ever seen that didn't work was one that came with my first P3. :) Didn't bother to figure out why, just traded it for a new one. 73, Jim K9YC __ 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
