Re: [Elecraft] Product Idea - 25 Watt PA for the K3
In keeping with my purchasing habits (I own the K1/2 and KX line) I'd rather see a compact, efficient, external, 1 W in /25W out (14dB) packer type amp offered to compliment my very versatile station. Just saying. 72 Myron WVØH Printed on Recycled Data > On Feb 23, 2017, at 1:00 AM, Rick WA6NHC wrote: > > Excellent replies so far. > > What we start with is a ten watt radio.

Re: [Elecraft] Linear PS Recommendations
Jim and Clay, It used to be that waythe RS linear models could not tolerate external voltage present when unpowered, not anymore. Astron has incorporated back-voltage protection through incorporation of some diodes installed in key locations to prevent this. You can verify if your supply has this modification by looking at the circuit board and see a 1N4001 type diode soldered across 2-pins (can't remember which ones off the top of my head) of the IC voltage regulator LM-723 chip and others hung in various places to protect the pass transistor as well. Usually soldered to the solder side of the circuit board so they are easy to spot. I can't remember is there were some small capacitors added as well. Any newer (like newer than 1990) linear Astron will have these installed.

That is why I really enjoy this mailing list. There are good people here that always offer great help. In the end the issue appears to be caused by the ribbon cable that connects the two halves of the radio. I had opened the radio a few days before the last time I had used it. I must have knocked the cable loose. While I was checking the radio I checked the connections of the cable and it was loose. After I got the radio back together I used your suggestions and the measurements were perfect. I also Googled your website. It was like finding a gold mine.

I might have an RF out issue with my KX3 but I am not sure how to test it. I have an Elecraft DL1 and a DMM that I figure I can use to check the RF voltages and verify the power out. However, I am not sure of the exact process on how to do this. If I am keying the mic on SSB do I need to speak into the mic to be able to measure the voltages or just key the mic with silence? I would assume I need to be speaking into the mic. The reason I ask this is because if I just key the mic with silence and the radio set for 10W with a input power supply of 13.5V DC I measure 4.7mv DC at the TP1 on the DL1 unit. If I speak into the mic I see voltages from 11 - 18V DC from the TP1 on the DL1 unit. It seems to me that I need to be speaking into the mic. I figure if I was checking the RF out in CW mode I would need to key the keyer in some fashion. I know this seems like an elementary level question but I would really like to verify the RF power out.

Re: [Elecraft] DTMF Tones on the K3
…unless you are digging weak signals out of the moon using it as an IF rig. Never such as thing as too much performance in an IF rig. I can see why EME-ers just want a little bit more. One of my Elmers, Al, W0PUF and I participated in the 1995 ARRL EME Contest with a Scientific Atlanta 10m dish spec’d for 4 GHz and a TS-700SP/HB amp with a pair of 4CX250Bs with an Ameco Rx conveter with no pre-amp…and got five QSOs from the W0BLK Club station out near Ellsworth AFB in Box Elder, SD. Worked the big guns only, like Al, WB5LUA and KB8RQ to name two. Ah, memories…I remember when we were working on the feed in the bird bath mode and a flock of migrating Sand Hill cranes were going south for the winter in formation directly overhead. I was in the focal point of that 30 foot dish and told Al on my HT to watch the flock as I made some noise. So Al got out the door in time to hear me issue some vocal shotgun blasts, “BOOM, BOOM, BOOM!” I shouted and be darned if they didn’t scatter…Awesome. They were way up there, like 10,000 feet maybe, who knows but I could hear them as if they were right there, trumpeting away. I miss Al.

Re: [Elecraft] RFI resistant Monitor
One thing I have noticed over the years is that the near-field noise is present with most any modern electronics. The switching frequency is between 200-300kHz and can be easily sniffed with a pocket AM radio (harmonics of that fundamental switching frequency are easily spotted with an AM radio). When I bring my CCrane Pocket Radio in the near field at the operating position, I can’t tune in the semi-local 600 KCOL out of Greely, CO. If I back up a few feet the noise level drops considerably and the station is audible again. The CC Pocket Radio has a fairly good front end with somewhat good selectivity but is still overloaded with IBOC noise. I have battery chargers, an old Dell 1501 laptop, an external HD with switcher, the list goes on. Common mode noise and strong near-field noise is the bane of my ham radio existence in this RFI rich environment.

It is also turning off when I operate on certain bands. I had exactly that experience with a Samsung that W4UAT gave me because it did that in his shack too. It also makes RF noise. The good news is that not all Samsung monitors are RFI dogs. I have two recent model Samsungs in my house and four in the shack. They are designed to run on power supplies labeled 14VDC, and the supply they sell you is a switching power supply that makes RF noise. I throw those power supplies away, cut the attached power cable and attach red/black PowePoles, and run them from either the 12V battery system in my shack or a small 12V lead-acid cell that I float-charge from a linear 12V wall wart. I also use ferrite common mode chokes on both the video cable that runs to the computer and the power supply cable "just in case" some RF trash is conducted to those cables, which the cables could radiate.

Re: [Elecraft] OT: Mobile operation "bible"
All, The coax length doesn't matter because of the following reasons. Assuming the tuner is at the rig, there is a run of any coax to the antenna feed point, and you have a fairly high Q low band antenna that can't QSY much. With short HF mobile antennas that are high Q the reactance at the feed point when you QSY beyond 3:1 or so makes the system very lossy regardless of how low a loss or how short of coax is in there. The power accepted by the antenna under these conditions goes down the further you QSY due to the large reactance leaving the dissipated power to be burned up in the coax (and some in the imperfect antenna tuner at the rig) no matter how low loss it is or how short it is. You cannot increase the power accepted by the antenna unless you bring the feed point back closer to 50-ohms somehow through external loading of the antenna. (Even then there are other loss factors to consider such as ground loss and radiation resistance). It's kind of like a "tug of war" between two Qs. The antenna Q and the tuner Q with the coax in the middle accepting all the power. 73/72, Myron WVØH Printed on Recycled Data > On Mar 31, 2016, at 11:09 PM, Jim Brown wrote: > > Bearing in mind that in a mobile installation, coax is too short to introduce > enough loss to matter, so it's merely a matter of making the rig's output > stage happy (and running at full output). __ 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

[Elecraft] KX3 Feature Request
I know this may be a nit but it would be neat if the VFO B knob would increment without rounding off the frequency. For instance, I participate in the foxhunts and find the fox. Then I use the DW SUB function and dial in the fox with the VFO A knob. If I use the VFO B knob it rounds off the decimal place and overshoots the target freq. If it were set to just increment of 1.0 I would land exactly where I want but it rounds off the freq and throws me out into left field. Thanks.
