Re: [Elecraft] K3: Noise Reduction (NR) in FM Mode
If I remember correctly it was Collins who first came up with the idea of using a simple secondary 'noise receiver' to blank the main receiver in HF SSB mobile installations using the KWM -1 and / or KWM-2A transceivers. The secondary 'noise' receiver was tuned to a frequency above 30 MHz and had its own small whip antenna. The FM receivers in our old RCA 'Carphone' series of VHF Land Mobile rigs used hard limiting before the discriminator to get rid of impulse noise and other AM gremlins. A modified version of the Collins system provides very effective noise blanking when used in a receiver covering the ham bands. Usually the noise receiver which provides the blanking pulses is tuned to a frequency clear of signals just outside of the band in use so that the main receiver is not blanked by strong unwanted in-band signals, which can be a problem with blankers driven by in-band noise especially during contests. One name given to this arrangement many years ago is the 'Evasive Noise Blanker'. Further improvement in overall receiver performance can be gained by removing the noise blanking gate, which is usually in the main receiver's signal path ahead of the IF filter(s), and use the blanking pulses from the noise receiver to turn the LO injection to the first mixer on and off - quite easy to do if any 'logic' is used in the LO system. The next improvement is aimed at dealing with storm static! Sorry to have drifted off subject! 73, Geoff GM4ESD. Matt Zilmer [EMAIL PROTECTED] wrote on Friday, June 06, 2008 at 6:24 AM At least with the Motorola Syntor X, they used a separate and very simple receiver to pick out impulse noise and used this secondary RX detector output to poke holes in the main RX audio. They called it an Extender and I believe it was only included with the low-band Syntor X. It is described as a Noise Blanker. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K1 drift cured (almost)
My K1 (#2059) has shown some frequency drift, especially when exposed to direct sunlight. It was in the order of 200-300 Hz. Maybe more if transmitting. Enough to be annoying. Now yesterday I put together a small huff puff circuit according to: http://downloads.hanssummers.com/sprat123.pdf Didn't use the oscillator section in the 74HC4060. Just connected pin 74HC4060 pin11 to one side of R12 on the K1 front panel board. At this point there's a good 5V swing on the 3 MHz VFO signal. Then a 100 pF cap from the varicap (5 mm red LED) to the connection C2/C5/C7/L1 on the K1 RF board. I used the Q10 output which gives a 20 Hz step, instead of the Q13 which would have given a 2,6 Hz step. I think it is nice to be able to hear the steps, to say if the circuit is working or not. Everything is mounted ugly style on a 30x50 mm unetched circuit board. I tested the temperature drift by removing the top lid and putting a 60 W desk lamp just over the TRX for some 5 minutes. The measured drift was 14 Hz and when the lamp was removed it slowly returned to the original fq. I think it is the 60 MHz oscillator that is drifting. However, it's a great improvement after all. Total time invested is approx. 3 hours. 73 Christer SM6PXJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: Re: [Elecraft] K2 - signal loss in band-pass filter
My 8V is as low as yours Kristinn but I do not have the same problem. This leads me to think that you have another problem...

But in my case I am not able to set the range of the S-meter properly, which I attribute to the low 8V level. My S-meter can not be adjusted to turn all LEDs off when no signal is present, and I do not get the S-meter quite up to full scale when the RF gain is turned fully CCW. If I am correct, this is due to the low 8V and that would be an incentive to get that voltage fixed. -- View this message in context: http://www.nabble.com/K2---signal-loss-in-band-pass-filter-tp17294418p17691603.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If you use a discriminator there was amplitude sensitivity in the detector so limiters stages were used in the IF before the discriminator. A ratio detector compensated for signal amplitude and didn't require a dedicated limiter stage. PLL-based detectors were also immune to amplitude variations. I worked my way through my last year in high-school working for an outfit that provided commercial two-way radio systems. (I did a *bunch* of installations in police cars.) We sold EF Johnson too. I hated those radios because the crystal ovens kept failing. Fixing them was not considered high on the list of fun jobs so guess who got to fix all the damned crystal ovens? :-) We did Motorola too. The Motorola stuff was just better built. We always felt that Motorola was the best, GE next, and EF Johnson was what you got when you couldn't afford anything better. I know that when I was building repeaters I preferred Motorola or GE RF decks. So blankers were never needed. Maybe Motorola didn't use good limiters.

[Elecraft] K3 and DXLabs
Well this is a little like talking about someone when they are in the same room. My normal day to day rig control program is also MixW. I too find the HRD interface a bit cluttered. Having said that, I've used Simon's programs for other things: FT-817 commander for programming memories for low orbit satellites and general rig control for the worlds most annoying radio (I can't see anything on the FT-817!). HRD DDE DDS-60 control. Along with a USB control program for the DDS-60 VFO I linked to HRD through Dynamic Data Exchange to send and receive frequency and band information to give me control of a homebrew Receiver. DM780 is a brilliant program but needs to be severed from the mother ship. I believe it will eventually be the gold standard of all digital programs. It truly is a joy to use with a very intuitive user interface. And before anyone brings it up, yes I did donate. It is a bargain.

[Elecraft] OT: Noise Reduction (NR) in FM Mode
Yeah, it's been all too many years, but hard limiters were not used in many designs and no FM detector is completely immune to noise. It brings back memories of just how loud and strong ignition impulse noise used to be back in the 50's before anyone did anything to suppress it! Used to roar through on 2 meter AM in the home station from cars hundreds of yards away at times! I was kidding about Motorola/ Working in land mobile with E.F. Johnson equipment, Motorola was always in our sights ;-) We did very well in the San Francisco area because we did have superior repeater sites. The Motorola gear was very good stuff as was the E.F.

Re: [Elecraft] N4PY software for K3 now available
Joe, Do you speak with personal experience or simply speculation? I believe Carl offers a 10 day free trial, so you can try it before committing to it, and once purchased, you get 1 year of free updates. The program is not posted for download, so you have to email Carl [EMAIL PROTECTED] if you would like to try a copy. His subscription service is only for the updates - your copy can be run forever even if you stop the subscription. I also believe it runs on all 32 bit Windows OSs - I have had it running on Windows 2000 and Windows XP, and Carl states that it will run on anything from Windows 95 to Vista (but not isat64), and I am not sure about NT. I no longer use N4PY software routinely - I migrated to Ham Radio Deluxe because of its integration for digital mode operation, but YMMV, that is just my choice. 73, Don W3FPR Joe Subich, W4TV wrote: As far as I know you can't run N4PY's software without first purchasing it but there are reviews on eHam.net .

[Elecraft] K3: 6M SSB audio hash
Hello: I've noticed some audio hash on my SSB signal on 6M only when the PA relay kicks in at 13 watts. My long microphone cable goes to a Multi-Switcher - W2IHY Noise Gate/Equalizer - Heil Goldline microphone. This completely disappears when I use a Kenwood hand mike direct to the K3. Thinking that this was a classic RF on the line problem, I clipped on multiple ferrite chokes with many turns on the cable coming from the K3, the Goldline mike, and in between the switcher on noise gate. This didn't even slow it down ! Hmmm. Interestingly when the PA relay is off at 8 watts, there is absolutely no hash. For now, I'll just use the hand mike on 6M (which requires a bit more mike gain) to keep a clean signal. Has anyone else noticed this ? Got a solution ? 73, Jamie WB4YDL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Xverters
Tom, My background is physics, not rf theory. But you're saying that the xv144 gives you better performance than a rig that was designed for that? I guess thats not too hard to believe, but still counterintuitive from my standpoint. Do you think I would get acceptable results from adding a texas microwave (or any brand) on top of the xv144 for 1.2 (or is it 1.4) ghz operation? My main interest in this area are the amsats but I've only managed a few sketchy qso's with a handheld before. Using transverters is uncharted waters for me. The only reason I'm considering one now is that 1. elecraft makes them and 2. a lot of folks seem to use them... so they cant be that bad right? I'm just skeptical of the added noise you introduce into the system with using them.

Re: [Elecraft] K3: 6M SSB audio hash
Jamie, The Heil headset will plug directly into the rear panel jacks - why not give that a try as an added piece of evidence that it is not the microphone. Most likely, something is being picked up on those long microphone cables and is not a K3 problem at all. Are all the mic cables shielded? Are all the cable shields connected to the plug/jack shell? They should be. I have not investigated the W2IHY equipment, but my understanding is that it is setup primarily for pro mics which use balanced AF lines for the mic audio. My suspicion is that there is something awry with the balanced to unbalanced arrangement when used with unbalanced line microphones such as you have there. As far as why it shows up only when the PA turns on, I can only speculate there too, but remember that there is more gain in the transmit stages when the PA turns on, and that added gain may make any small AF line pickup more pronounced in your transmit signal. If it were from RF coupling into the audio, it would vary smoothly from low power to high power and all RF levels in between - you indicated only that it was there with the PA on, but did not say that it got worse as power was increased. 73, Don W3FPR James C.

RE: [Elecraft] K3: 6M SSB audio hash
Thanks Don: I still suspect the 10' cable to the NCS Multi-Switcher is acting like an antenna at that high a frequency - however, nothing changed with multiple ferrite chokes along this line. Good idea to check the back mic connector, although direct attachment of the hand mike and the headset to the front connector did not cause the hash. The cable is a very well constructed cable made by NCS for the K3 (Kenwood). I can certainly ask NCS (I forgot his name, but he's very approachable) regarding the shielding characteristics. I use the same cables for the other radios. You asked if it gets worse with increase in power - yes, but not very much. It's nearly an all or nothing deal. When using my K2/100 with 6M transverter through the W2IHY unit, there is no problem at all. The only difference is a longer cable to a different port on the multi-switcher to reach the K3 - which is on the other side of my monitor/desk. 73, Jamie WB4YDL -Original Message- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2008 5:17 PM To: James C.

[Elecraft] K3 BETA FIRMWARE RELEASE -- MCU Revision 2.00
K3 beta-test firmware revision 2.00 is now available. It includes one new feature (transverter band data) and two improvements based on feedback users sent us about revision 1.99. Full details appear below. The use of beta-test firmware is encouraged, but optional. Please send any problem reports to [EMAIL PROTECTED] For instructions on how to obtain and load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 2.00 / DSP 1.77, 6-6-08 BAND DATA FOR TRANSVERTERS: The BAND0-3 outputs on the 15-pin ACC jack can now be used to control transverters as described in the Owner’s Manual (revision C, page 18-19). To enable this feature, set CONFIG:KIO3 to HF-TRN (which outputs band decode data for both HF and transverter bands) or TRN (transverter band data only). The default is NOR (HF band data only). CW MODE SPEAKER ARTIFACT ELIMINATED: Some operators reported a periodic burst of noise coming from the speaker when headphones were used in CW mode. This has been corrected. MIC BUTTON FUNCTIONS DEFAULT TO OFF: There’s now a menu entry for turning the mic up/down buttons on or off (CONFIG:MIC BTN). The default is OFF, which makes these buttons inactive. You should turn it ON only if you have a mic whose up/down buttons provide contact closures to ground, with no resistors in series or in parallel (such as a Kenwood MC-43). Some mics have internal resistors and are not compatible with the K3’s up/down feature. If you try to use such a mic (by setting CONFIG:MIC BTN to ON), VFO A may scan continuously. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Xverters
The FT736R is not known for having much dynamic range. I own one. :-) Its a great overall rig for VHF/UHF use with multiple bands in one box, but as a result there are many compromises. Most multi-band VHF rigs compromise their dynamic range, phase noise etc. In general a high performance transverter, like our XV family, paired with a high dynamic range rig like our K3 and K2, will outperform most multi band VHF/UHF rigs for receive performance. The Elecraft XVs are designed to match the wide dynamic range of the K2 and K3. Plus their front end pre-amps are very quiet. While they will work with most HF rigs, they tightly integrate with the K3 and K2. The K3 supports up to 9 transverter bands (6 on the K2) with correct VHF/UHF frequency display and individual transverter offsets programmable on each band. Each of our XVs will power up and drop on/off line as they are selected by the K3 or K2. Also, we support using an XV, like the XV144, as an intermediate IF for microwave use. 73, Eric WA6HHQ cptpatmcd wrote: Tom, My background is physics, not rf theory. But you're saying that the xv144 gives you better performance than a rig that was designed for that? I guess thats not too hard to believe, but still counterintuitive from my standpoint. Do you think I would get acceptable results from adding a texas microwave (or any brand) on top of the xv144 for 1.2 (or is it 1.4) ghz operation? My main interest in this area are the amsats but I've only managed a few sketchy qso's with a handheld before. Using transverters is uncharted waters for me. The only reason I'm considering one now is that 1. elecraft makes them and 2. a lot of folks seem to use them... so they cant be that bad right? I'm just skeptical of the added noise you introduce into the system with using them.

[Elecraft] WB3AAL NK8Q out on the Appalachian Trail 7 June 2008
Hello Happy Trail Days, 7 June 2008 is the National Trail Days in the U.S.A. http://www.americanhiking.org/NTD.aspx Mark de NK8Q and I, Ron de WB3AAL, will be out on the Appalachian Trail on Saturday. We plan to meet at 7 AM or 11:00 UTC and make our way to The Pinnacle that is South on the AT from Eckville, PA. When we arrive at the parking lot at 11:00 UTC we will decide if we will hike to The Pinnacle, highest spot on the AT in Berks County PA or go to another location. This spot is very popular and becomes very crowded on nice days. We should be on the air between 8:30 AM or 12:30 UTC and 9:00 AM or 13:00 UTC. I, WB3AAL, will be using my K1 on the 21.060, 14.060, 10.106 or 10.116 and 7.030 or 7.040 Mhz. Mark, NK8Q, will be using his KX1 on 14.060, 10.106 or 10.116 and 7.030 or 7.040 Mhz. Mark will also be taking some Rockmites for 7.030 / 7.040 and 14.060. We will stay on the air until the QSO die off or until 12 noon or 16:00 UTC. The wx is to be very hot and humid in EPA land. Mid 90's and high humidity. So if you are up and about look for us on the HF CW bands. If you work us please spot us on the X Clusters and / or the e-mail list. 72 and Thanks, Ron Polityka WB3AAL www.wb3aal.com www.n3epa.org/ K1 - SN 01011 K2 - SN 01392 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3: 6M SSB audio hash
Jamie, Since you did not have a problem with the K2/xvtr with the same setup brings up another thought - the K2 required a high level of mic audio input while the K3 has plenty of mic gain. If you have not tried it yet, you may want to reduce the mic gain setting on the K3 and increase the gain in your external units. Using a higher level of audio drive to the K3 just might reduce the problem or even eliminate it. If nothing else, it might point the finger at something you may not have considered. I know I am posing more questions rather than providing answers, but that is partly how troubleshooting is done. 73, Don W3FPR James C. Hall, MD wrote: Thanks Don: I still suspect the 10' cable to the NCS Multi-Switcher is acting like an antenna at that high a frequency - however, nothing changed with multiple ferrite chokes along this line. Good idea to check the back mic connector, although direct attachment of the hand mike and the headset to the front connector did not cause the hash. The cable is a very well constructed cable made by NCS for the K3 (Kenwood). I can certainly ask NCS (I forgot his name, but he's very approachable) regarding the shielding characteristics. I use the same cables for the other radios. You asked if it gets worse with increase in power - yes, but not very much. It's nearly an all or nothing deal. When using my K2/100 with 6M transverter through the W2IHY unit, there is no problem at all. The only difference is a longer cable to a different port on the multi-switcher to reach the K3 - which is on the other side of my monitor/desk. 73, Jamie WB4YDL -Original Message- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2008 5:17 PM To: James C.

Most likely, something is being picked up on those long microphone cables and is not a K3 problem at all. Are all the mic cables shielded? Are all the cable shields connected to the plug/jack shell? They should be. I have not investigated the W2IHY equipment, but my understanding is that it is setup primarily for pro mics which use balanced AF lines for the mic audio. My suspicion is that there is something awry with the balanced to unbalanced arrangement when used with unbalanced line microphones such as you have there. As far as why it shows up only when the PA turns on, I can only speculate there too, but remember that there is more gain in the transmit stages when the PA turns on, and that added gain may make any small AF line pickup more pronounced in your transmit signal. If it were from RF coupling into the audio, it would vary smoothly from low power to high power and all RF levels in between - you indicated only that it was there with the PA on, but did not say that it got worse as power was increased. 73, Don W3FPR James C.

Thinking that this was a classic RF on the line problem, I clipped on multiple ferrite chokes with many turns on the cable coming from the K3, the Goldline mike, and in between the switcher on noise gate. This didn't even slow it down ! Hmmm. Interestingly when the PA relay is off at 8 watts, there is absolutely no hash.

RE: [Elecraft] K3: 6M SSB audio hash
I have not investigated the W2IHY equipment, but my understanding is that it is setup primarily for pro mics which use balanced AF lines for the mic audio. My suspicion is that there is something awry with the balanced to unbalanced arrangement when used with unbalanced line microphones such as you have there. There is a significant problem in using balanced input with any amateur mic - including Icom, Kenwood, Yaesu and Heil. Yaesu, Kenwood and Heil connect the shield of the mic cable to the mic return and not chassis (ground). Icom uses the shield as the mic return. When the shield of the mic cable is tied to the low side of a balanced input, RF that SHOULD go to ground/chassis is forced through the mic preamp instead. With the shield tied to the mic return there is effectively a 10' piece of wire (antenna) connected to the mic input unless the mic return is tied to the chassis and the chassis is connected to a solid RF ground. 73, ...

Most likely, something is being picked up on those long microphone cables and is not a K3 problem at all. Are all the mic cables shielded? Are all the cable shields connected to the plug/jack shell? They should be. I have not investigated the W2IHY equipment, but my understanding is that it is setup primarily for pro mics which use balanced AF lines for the mic audio. My suspicion is that there is something awry with the balanced to unbalanced arrangement when used with unbalanced line microphones such as you have there. As far as why it shows up only when the PA turns on, I can only speculate there too, but remember that there is more gain in the transmit stages when the PA turns on, and that added gain may make any small AF line pickup more pronounced in your transmit signal. If it were from RF coupling into the audio, it would vary smoothly from low power to high power and all RF levels in between - you indicated only that it was there with the PA on, but did not say that it got worse as power was increased. 73, Don W3FPR James C.

My long microphone cable goes to a Multi-Switcher - W2IHY Noise Gate/Equalizer - Heil Goldline microphone. This completely disappears when I use a Kenwood hand mike direct to the K3. Thinking that this was a classic RF on the line problem, I clipped on multiple ferrite chokes with many turns on the cable coming from the K3, the Goldline mike, and in between the switcher on noise gate. This didn't even slow it down ! Hmmm. Interestingly when the PA relay is off at 8 watts, there is absolutely no hash. For now, I'll just use the hand mike on 6M (which requires a bit more mike gain) to keep a clean signal. Has anyone else noticed this ?

RE: [Elecraft] Elecraft SSB Net -- declare dormant for summer?
I put out the message below, and nobody replied. Meanwhile, the Wiki site has announced that the SSB Nets are inactive during summer 2008 until further notice. Refer to User Nets header at: http://www.zerobeat.net/mediawiki/index.php/Main_Page So please be informed -- It is NOW dormant. Perhaps it will thrive in the winter season. There is no designated net control or manager, so when the time comes, I encourage anyone to take charge. Thanks to those who showed up on numerous occasions.

You lose the benefit of the balanced circuitry's ability to reject noise, but the input will work fine. The correct wiring is simply hot to one side, shield to the other side AND the chassis. That is *NOT* what is happening ... the mic connection does not simply unbalance the mic input because one side of the preamp is still not grounded. What is happening is that the mic is connected to the preamp in a balanced configuration but the shield is left floating on the mic end and tied to the mic return at the transmitter input. The mic return is then tied back to the chassis through an RF choke (DC return). What happens is that you now have a shield (unbalanced for RF pickup) over top of the twisted pair (nicely balanced) mic leads. Worse, the RF choke from mic return to ground makes it almost certain that any RF on the mic shield will be forced through the preamp instead of being bypassed harmlessly to the chassis/ground. It would be better if the mic return (and shield) was connected directly to the chassis at the mic connector than the present situation ... but not as good as if the shield were connected to the chassis (usually PTT ground) and the mic treated as a floating/balanced input. 73, ...

Sometimes there is some leakage on the little KIO3 digital I/O board

Gary, thanks for shipping the new front panel. I just finished
recalibrating the rig and have been listening to some qsos.
Replacing the front panel appears to have cured my problems. The K3
turned on properly and has responded appropriately through each step of
calibration. (This time I was sure to save the configuration on my
laptop...just in case.
Once again I feel compelled to compliment Elecraft on the fit and finish
of the K3, as well as the superior customer service. I know that
Elecraft will take whatever reasonable steps are necessary to satisfy
their customers. I deal with tech support with various IT and telecom
organizations so I can legitimately compare.
Well tomorrow I'm going to get my feet wet and do some hamming.
Good Night All...and thanks for all your help.
