Re: [Elecraft] RFIth
The impedance increases with the square of the turns. 2 turns = 4 times the impedance. It would take 4 chokes in series to equal one choke with 2 turns. A "turn" is one pass through the middle. More turns is better until we get to very large chokes where the inter-coil capacitance lowers the impedance.

[Elecraft] K3 Sub Rx RF Gain issue and TX sticking
The RF Gain control on the Sub RX acts weird. It will seem deaf until 3 o'clock on the dial. Once past 3, the gain jumps up and then is linear if you turn it down. This pattern will repeat if you turn off the Sub Rx and turn it back on again. The main RX Rf Gain control is smooth and linear all through the dial range. I have done the RX calibration routine on both receivers. During Field Day, if I hit the Esc Key or the paddle to interrupt a CQ (N1MM+) , my external keyer (MKUSB) would stop keying but the rig would stay in transmit mode. Tapping the XMT button would put the rig back to RX mode.

[Elecraft] Ham enthusiast arrested
Ham-radio enthusiast, Hezekiah Bambershoot, of Ft Jackson, was arrested yesterday at police headquarters for disorderly conduct and assaulting a police officer.Bambershoot initially came to headquarters reporting he had been victimized by buying a radio from a mysterious Californian named Ellie Craft. Ms Craft allegedly took advantage of Bambershoot by claiming to have down-conversion which he mistook for a syndrome of the same name. Bambershoot was happy with his purchase until his friends told him all the problems he should be having with his new radio. According to Police spokesman, Ken Wood, "The poor man was distraught and raving about roofing filters.What the heck are roofing filters?" The arrest report filed by fellow-ham, Officer Ike Com, listed Bambershoot's original complaint as "radio mushiness" but notes, "I told him all my radios sound mushy but he was upset he couldn't hear it on his.When we tried to calm him down he became unruly." Su Yae, an EMT called to the scene, defended Bambershoot saying, "When I got there they claimed he was making clicking noises with his keys but I never heard any key-clicking.The poor man was just frustrated because his purchase had so many faults he couldn't find.I feel sorry for him." Bambershoot is being held on $10,000 bond.Police are still searching for the elusive Ellie Craft. -- Buck k4ia __ 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] K3 AF Gain
The AF Gain dial can also be used like a balance control. When you say they are both set the same, what is probably happening is you have the balance control over to the one side. Look in the Tech Menu for a setting called SUB AF. The choices are nor and balance. If you are in balance mode and you want them to be the same you have to set the Sub AF Gain knob to the middle.

Re: [Elecraft] K3 - Sub RX audio to right Line Out SOLVED
In the interest of future readers, here is what I found. I had the LIN OUT menu item set to NOR 10 as recommended. In fact, they warn of going over that level. However, when you turn on the SUB RX, the signal is split and you lose 3db. This can be heard in the headphones. It seems it also affects the Line Out. When I increased the LIN OUT level to 35, the Sub Rx could be heard in the right channel of the Line Out. I have no idea how linear the LIN OUT level setting is but I suspect that increase to 35 is what was needed to overcome the attenuation that occurs when the Sub Rx switches in. Now the issue is, the output seems unbalanced with the Main Rx signal on the left channel of the Line Out jack being louder than the Sub Rx signal on the right channel. I am able to compensate for this by turning down the Main Rx gain control on the MicroHam MKII. I wasn't able to even them out with the RF Gain control on the K3 but I will play around with that some more.

Re: [Elecraft] K3 in WPX SSB with 2.7 roofer
I have found that if I shift the passband I can still understand SSB even though the DSP filter says it is only 1.1 khz wide. Try it and the signal will be very clear once you hit the sweet spot. I think this is because the intelligence carrying portion of the voice is not necessarily in the center of the passband. Buck k4ia On 3/31/2014 10:52 AM, George Danner wrote: One of the things that Bell Labs found in adding loading coils to phone lines (to reduce the high frequencies) was that in an audio system if you reduce the high frequencies then you needed to also reduce the low frequencies to keep the intelligibility constant. Since a phone system needed intelligibility above fidelity; Bell Labs just decreased the coupling capacitors to reduce the low end while using the line loading coils to reduce the high frequencies. I tend to use lo-cut to improve "listen ability" when I cut the high end. I use a 1.8 kHz filter for a morning SSB net that has other nets 3 kHz away usually on both sides. Some of the transmitters on the adjacent frequencies can't fit in 5 kHz much less being 3 kHz away. The 1.8 kHz filter is the best solution - the filter skirts along with the DSP skirts help the most I can expect. I would recommend adjusting Hi-Cut for the interference and Lo-Cut for the best compromise on fidelity & intelligibility; if that switches in a tighter filter, then that might be needed. My 2 cents! 73 George AI4VZ -Original Message- From: Al For years I have heard folks state that 1.8 kHz is mandatory for SSB contesting... but I have never understood how one could put up with this narrow bandwidth for long.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem UPDATE
An OCF is an unbalanced antenna and it must have a choke to keep RF off the feed line into the shack. I use about ten turns of coax on a 4 inch PVC pipe right outside the wall where the feed comes into the house. It might be more or less, I am not at home to look. You can research it. Other choke baluns would help, if they present a high enough impedance. That seems to have cured RFI problems for me but I have occasionally felt like I needed more isolation. Many people have advised me to get rid of the OCF and go with something balanced but it suits my multi-band needs for now. I am pretty sure RF on the feed line would cause the tuning circuits in the KAT to act crazy. I'll leave that one for the Elecraft gurus to answer. Buck k4ia On 1/8/2014 5:57 AM, Ray Coles wrote: As the original poster under this heading I figured you might be interested to know what I have achieved so far, even though I am not yet ready to send the white smoke up the chimney. Briefly, my problem was that my KAT500 would go into uncommanded tunes during a QSO, usually on digital modes.The practical result was that I had to restrict TX power to less than 40Watts on most bands to avoid a burst from the Chicago Piano in the KAT. I had assumed an antenna/feeder problem and had changed every last connector, wire, balun and insulator in my system before asking for help from the Reflector Brains Trust. All of the other people who subsequently reported a similar problem made me feel a little better, and I also received a lot of diagnoses and practical advice which I have followed or will follow soon. One of the simplest was from Ron WB4OOA: Carry out a K3 Gain Calibration via the K3 Utility (I had to download the latest Utility version to make this work properly) then Install the KAT500 V1.42 Beta (Not quite as easy as it sounds). After this things were better, and my power setting on the K3 always appeared on the KPA500 wattmeter. I could now operate at higher power on some bands but had to stay below 40W on 40m. I had also adjusted the per band retune trigger SWRs upwards via the KAT500 Utility which also helped a little. I remain convinced though, that the basic trigger problem lies with the antenna system (an OCF multiband dipole) and I am continuing to work on this aspect using my analyser. Why it should have suddenly kicked off after many months of solid performance, and why changing everything hasn't yet cured it remains a mystery. My next steps are to try a choke balun on the feeder (parts now to hand) and to prune the antenna to get a better resonance on the bands of interest. Now if only this darn rain would stop!

Re: [Elecraft] K3 / KPA500 / KAT500 Tuning

Re: [Elecraft] W2 - Possible Addition to Station
I use both the W2 and the KAT500. The W2 is closest to the antenna and tells me what the SWR really is. The KAT500 tells me what the transmitter is seeing. You really need both. Buck k4ia K3 # 101 KX3 #715 On 9/2/2013 6:44 PM, Don Wilhelm wrote: Jim, Under normal operation, the resolution between an SWR of 1.3 and 1.5 is not of impo0rtance (pardon those who always strive for an SWR of 1.0). At HF that amount of resolution is unimportant unless you are doing measurements on your antenna system (that is different from normal operating) - and in that case, you would likely be using the computer connection to provide you with the greater resolution values. I sense that several hams are offering their W2 wattmeters for sale because they have purchased the KPA500 and/or the KAT500 and find that the SWR display on those devices renders the use of the W2 redundant. The W2 *is* an accurate wattmeter. I cannot comment on the accuracy of the MFJ unit. In general, wattmeters are getting more accurate, but some are still rated at 20% of the full scale readings - that is typical for analog meter readouts. So bottom line, do you want accuracy or do you want precision indication of power and SWR. If your concern is for SWR only, keep in mind that almost all wattmeters are accurate when they read an SWR of 1.0. 73, Don W3FPR On 9/2/2013 6:17 PM, Jim Bennett wrote: Currently my station includes a K3/100, P3, Ameritron AL-811 amplifier, and the LDG AT-600 ProII auto tuner with the M-600 analog display.

The above equipment does not have the ability to display SWR or power output on 2 meters with the amplifier online. So, I've been looking at something to fill this gap. One option was the $80 MFJ-873 V/U meter. A second, much more expensive option is the Elecraft W2. I'm not a big fan of a string of LED's for measurement of anything, as it simply does not give the resolution one would like to have. I dealt with that when I had the Elecraft KPA500 last year. Nice to look at, but not overly big on resolution. What I DO like about the W2 is the software that is available from the web site - the W2 Interface Program. In addition to bar graphs for SWR and Power Fwd/Ref, there is a numeric display with a LOT more resolution than one normally would see with any analog "meter". Since I nearly always have my MacBook Air turned on when I operate, needing to have a computer for higher resolution than LED's isn't an issue for me. __ 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 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] KUSB Noise Query - K3
I have found that I must be sure to screw in (not just plug in) the serial connector on the back of the K3. If I don't, I will hear a pulsed rushing noise from the USB.

It turned out to be a fault with the sound card, which took out the serial connections. When I first built the K3, I bought a cheap Prolific USB converter, which radiates awful noise over the spectrum. I decided to bite the bullet and buy the proper lead, which arrived today. Using my Toshiba laptop, on battery power, I get a couple of s points of noise on 10M with the KUSB connected and HRD fired up. This is using my 2 element DJ4VM quad, which is fed with 300 ohm twin into the shack, i.e. near the laptop. On LF, I can hear the pulsing information, in sympathy with the flashing LEDs on the KUSB on 160M at quite a high level. I can even detect this when fed into a Marconi dummy load. The K3 and the tuning units are bonder to an RF earth - a copper stake about 8 feet away from the K3. I have tried choking the USB lead at the laptop end, which does reduce the noise to a degree. The question I have is - am I being unrealistic in expecting zero noise to be radiated from these adaptors? Does anyone else have this problem - or has anyone looked for it? It is not very noticeable on CW or SSB. To hear it best, listen in the AM mode with the AGC off. On SSB it sounds like band noise. Is this a problem JUST with USB adaptors or can I expect silence when connecting a computer via RS232 to RS232. If not we are sacrificing a low noise floor for the convenience of computer control.

Re: [Elecraft] [K3] need help with hiss on ssb receive
Reduce your RF gain, Use the attenuator on the lower bands. The reason it is the same with the AGC on or off is because with AGC off the receiver is running full bore amplifying all the background noise. You must reduce your RF gain until the background noise (hiss) goes away so the signal you want to hear will be just above the silence. Then, set the AGC controls to the defaults or follow some of the other suggestions on this list.

Re: [Elecraft] Elecraft newbie considering K3 vs KX3
You are going to get a ton of answers but here's my take (and I own both). It all depends on what you want to do. I would compare it to the choice of a laptop computer vs a desktop or a 5-shot 38 revolver vs a 13-round 45 semi-auto. Either one will get the job done but they have different pros and cons. If you want a light weight, low power consumption rig that is really easy to move around, the KX3 is better. It is perfect for hikers, campers, backyard operators, battery power and all-around fun with much better performance than the typical "trail" rig. Not so sure how that will change once you add the 100w amplifier. I suspect it and the larger power supply will be more of a desktop profile at that point but without the additional performance of the K3. If you want maximum flexibility, more power, more features you go for a desktop. The K3 has become the standard by which all other contest quality rigs are measured. Some of them are as big as suitcases. The K3 is small by comparison but it is lunchbox-sized compared to the KX3 which is more the size of a VHS tape. Either one is an excellent choice but you wouldn't want to haul a desktop up a mountain and you wouldn't want to use a laptop to do high resolution gaming, video editing or multiple DVD burning. So, ask yourself, what do you want to do? Most will say you need both. Buck k4ia On 10/16/2012 4:22 PM, KF9QL wrote: > Hello all, Tom here.

Re: [Elecraft] K3 - Filter suggestions for new builder
You have chosen the bread-and-butter choices. You may find they are all you need. You can add others later, if needed. Could you go with less? Personally, I only use the sub-receiver for chasing split DX. I don't need razor sharp filtering - in fact, I need to hear a broad spectrum so I can figure out where the DX is listening. Therefore, I elected no special filters in the sub. If you use the sub for diversity reception, you probably need to filter it up.

[Elecraft] Sherwood ranking
Very well done indeed. But, I am confused. How is the ranking decided?

Re: [Elecraft] K3 Filter question Again?
My thought on the 5 pole was that it would give you some protection but because the skirts were not as steep you could hear someone calling you off frequency better. They would be down but not out. The 5's have slightly less insertion loss and are cheaper. On the other hand they need an offset adjustment and therefore don't lend themselves to diversity reception as well. I think the answer is: it depends on your style of operating and what you want to spend. The reason there is more than one choice is that one size does not fit all. Or, as my Nana used to say, "that's why they don't make it all vanilla." Sent from my iPad On Aug 8, 2012, at 10:04 PM, Matt Zilmer wrote: > Those 8-pole filters have steeper skirts.

[Elecraft] KX3 I/Q output for pandapter
I am fooling around with an EM0202 external soundcard and NaP3 which works just fine with an LpPan pandapter providing the I/Q from my K3 but I am not having much luck with the KX3, I have turned on the RX I/Q in the menu and run the I/Q output from the KX3 to the soundcard. I had to crank the gain way up but the signals are not there - just images, a blip in the center frequency and mirrored spurs on either side. . Before I go crazy trying to get this to work, is it fully implemented at this time and should it work?

It looks like I can assign a simple menu item to PF1/2 (page 19 of Operator Manual) but I can't find anything about Macros. Question #3: Other than PF1 and PF2, how do I assign macros to other keys?

[Elecraft] KX3 Got a good feeling about this
My KX3 (ordered Dec 29) was delivered today. Hot Doggity! I started the build and it is remarkable As always with Elecraft, the unpacking is to behold a work of art. How do they put together such a beautiful package? The hardest part for me is discriminating (is that a bad word?) between a 1/4 inch and a 3/16 inch screw or a 2-56 vs a 4-40 thread. If you work with this stuff every day (I don't) it might be easy. But, it is a puzzle with easy answers. Don't be intimidated by my comment. If the instructions say there are 7 of something, you can figure out which of the doohikies in front of you have 7 - and that must be it. Thanks Wayne and Eric. You have redefined the modern amateur transceiver from the technical side in a revolutionary way. You went against the conventional wisdom of quadruple up-conversion and produced receivers of remarkable sophistication. Then you did the impossible and kitted it out.

[Elecraft] Connect your radio and computer wirelessly
This popped up on the KX3 reflector but I thought it should be here too. Pardon if someone beat me to it. Here's a neat new device that connects your computer and radio over an ad hoc wireless network. It is really designed for the iPad and the maker's program HamLog but I see it having application here. Communication with the computer is wireless and communication with the rig is over its serial port. No USB or serial port from your computer is required. 1. Take your iPad to the field and log your contacts with HamLog, then import them into your home logging program (yes the program supports ADIF file transfers). HamLog supports Elecraft radios, including the KX3. 2. Maybe you've had bad luck with ProLific and FTDI drivers trying to run USB>Serial converters. You could have your radio and computer talk wireless while you access the internet over a network cable. Go to pignology.net I have no connection with the company - just interested in the possibilities and marveling at the creativity. -- Buck k4ia __ 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] AD-1-K doesn't have blocking capacitor, Heil claims
Yes but. . . The Mic pinout used by Elecraft is the Kenwood pinout. So, you would use a Kenwood adapter with a Heil product.

Re: [Elecraft] K3 Hum on transmit
I have found, on occasion, I get a raspy pulsing noise on the audio. I believe it is coming from a USB connection through an audio switching device. I must make sure the RS232 plug on the back of the K3 is securely screwed on (not just pushed on) and wiggling the audio plugs in the row below the RS232 and the ACC jacks will make it go away. I haven't figured out exactly which one it is yet. The K3 is star-point grounded with the computer case but not the audio switching device. I have done the pin1 mic mod.

[Elecraft] K3 and LP 100A calibration
Following up on an exchange I had some time ago with Larry, I couldn't figure out why his LP100A watt meter was reading low - even after he had calibrated it in his shop. With some help from Don W3FPR, I got it figured out and offer this for future reference to others who may experience the same confusion. There is a procedure on page 49 on the K3 manual to calibrate the power out on the K3. After doing this you calibrate "per-band" using a procedure on the same page. I didn't realize the K3 power meter is not absolute. In other words, this procedure on page 49 is what tells the K3 power meter how much 100 watts really is (actually 50 watts is used for the test). I had calibrated my K3 watt meter some time ago against an MFJ-949E antenna tuner watt meter. (OK stop laughing). Turns out the MFJ unit and another cheapo SWR meter I had here were both way off. The MFJ reported 100w when the true output was more like 70. As a result, even though my K3 watt meter read 100w, in perfect agreement with the MFJ, both were wrong. I re-calibrated, per Don's suggestion, using the LP100A as the reference. Now 100w on my K3 shows 100w on the LP100A and 125 watts on the MFJ. As an added bonus, my amplifier now puts out full power as it was being under driven before. -- Buck k4ia K3 # 101 __ 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 Internal Tuner Question
Well here's one for you: My setup is K3 to wattmeter to dummy load. The K3 says 100w If the external wattmeter is: MFJ 949E tuner/SWR meter (tuner out of circuit) it says 100w cheapo Radio Shack SWR meter 100w LP 100A digital wattmeter says 70 watts Elecraft W2 says 70 watts Yes, I have run the transmitter calibration routine in the K3 Utility program. SWR in all three cases is nominal 1:1 The result is the same to a real antenna although the SWR is not 1:1 What could be causing the external-sensor type wattmeters to read low?

Re: [Elecraft] N1MM with K-3

Re: [Elecraft] K3: Contesters using N1MM voice keyer versus K3DVK
The advantage of the N1MM voice keyer is that it will automatically send the next message depending on where you are in the logging sequence. You can also go so far as to record individual letters and it will string them together to "say" callsigns and incremental QSO numbers. Its a lot of work to do that trick but it can be done. If you use the K3DVK, you have to take your hands off the keyboard to punch a button on the front panel of the radio and your number of available messages is much more limited. And, the N1MM voice keyer is free. Buck k4ia K3 # 101 On 9/3/2011 9:46 PM, DOUGLAS ZWIEBEL wrote: > Hi... > > I am a fossil using CT on DOS.

Re: [Elecraft] low power on 6 meters
I notice high swr when my AL572 is in the antenna circuit - even when turned off. When I hook the coax directly to the K3, the swr is 1:1.

Re: [Elecraft] K3/ Microkeyer/N1MM lockup at FD
Joe You're right - the correct name is the MicroHam CW Keyer. Router version 7.7.1 Was using the latest N1MM 11.5.1 I was not using a PTT cable - I had "PTT via Radio Command" checked in the N1MM serial port setup. I did not have "Energize Hardware and Software PTT" because I wasn't using Hardware PTT. Should I check it anyway? I don't think this is a MH issue. Sounds more like you suggested, N1MM is not releasing the PTT properly when a key is struck - or the K3 is being confused by the software command. It may be a data-clash timing issue depending on exactly when in the sequence of commands flying back and forth I hit a key. I say this because the lockup doesn't happen every time I interrupt the auto CQ sequence. In the heat of battle I can't say for sure, but it seems like it happened if I hit a key right about the same time the auto CQ was just getting started. If it is a data clash, one solution could be to hook up the PTT line and use hardware PTT. What do you think?

[Elecraft] K3/ Microkeyer/N1MM lockup at FD
The mighty K4TS, Rappahannock Valley Amateur Radio Club, 8A Field Day featured 1 K3 - mine on 40 CW. 40 CW made 925 contacts but only 854 after eliminating the dupes. The K3 really strutted its stuff and it was obvious what a superior rig it is when I went around and listened to what other radios were hearing - a mush of noise and IMD that made operating almost impossible Saturday night. Several ops just gave up as the noise and close signals crushed their rigs. They marveled out how clear the K3 sounded. No news there. I did have one glitch that happened several times. I proffer it to all three groups for comment. The setup was a K3, N1MM and a MicroHam MicroKeyer (the CW only model). The keyer would start to auto-send CQ just as I heard a call. When I hit a key on the computer keyboard (including the ESC key), the keying should stop and the radio go into receive mode. Several times, the keying stopped but the radio remained frozen in transmit mode. The PTT light was ON on the MicroKeyer, the transmit light was ON on the K3 and N1MM wouldn't respond. Paddles plugged into the MicroKeyer did nothing. The "fix" was to turn off the K3 and turn it back on again. That would release the PTT and all would go back to normal. It didn't happen every time but it did happen a lot.

Re: [Elecraft] K3: How to set Split in PSK31 Data mode
Press 2 times quickly to transfer both frequency and mode to VFO B. Then, press and hold to go into Split Operation. Or, even easier, using a program like WinWarbler that decodes multiple traces, you can pick your transmit frequency and watch the receive side in a separate frame. That is the way I would do PSK split.

Re: [Elecraft] Power Supply For K3?
35A Astron linear running for 24/7 10 years at home with no issues. Samlex 1223 switcher at Field Day for 24 hours of constant CW in Virginia-summer heat with no issues. There is no "head room" in this supply to run any other accessories so it is a bare minimum for capacity. I do not hear any RFI with it but I only operate 40M. I understand Samlex supplies are quiet but, as others have pointed out, there is bound to be noise somewhere.

Re: [Elecraft] Mac Grounding
I found it necessary to ground my computer chassis to prevent the incursion of RFI. I scraped off some paint on the rear and bolted a ground strap from there to my star point ground system for the shack. It was not an issue of safety ground but of RF being induced into the computer from the nearby antennas. My RFI manifested itself as distortion when using the soundcard as a DVR for contests. The recording sounded fine but what went out over the air was distorted. I also had to perform the pin1 mods to my early serial number K3. Anyone having RFI issues should investigate these mods. Info is available on the Elecraft website under Alerts, Enhancements and Application Notes. There are two mods - one to the microphone jack and one to the real panel. After doing the above, I have had no more problems with RFI. Buck k4ia On 4/12/2011 2:07 PM, Edward R. Cole wrote: > None of my computer chassis are grounded directly to my radio > grounds.

I don't operate phone much but when I tried to I heard a weak pulsing buzz corresponding to the USB port polling the radio. I also had trouble getting the mic gain and compression right. It seemed I had to turn both way down and yell in the mic because if I turned either up, I got a rushing noise in the audio. There was no RF "bite" and I was using a star-point ground system so I assumed I did not have any RF in the shack. I asked Joe at Microham about it and he suggested the two mods on the Elecraft website dealing with bypassing a few RF chokes and modifying the microphone jack. These mods are for early K3s and the instructions tell how to check if you need them using a DVM. My K3 #101 was a candidate. Neither mod is particularly difficult and the only part required is a bit of wire. I am glad to say that after performing the surgery the pulsing buzz is gone and the mic gain and compression settings are working normally. Night and day difference. I offer this as advice to anyone who experiences issues with noise in the audio or difficulty adjusting the mic gain and compression.

Re: [Elecraft] An AGC story
As I understand the graphs and operation: AGC Threshold is the point at which AGC action starts. The higher the AGC THR number, the higher point at which AGC starts. The highest AGC THR (8) starts AGC action at S3. That is a pretty low level but any setting less than THR 8 starts the AGC action with even less signal. AGC SLP is how aggressive the AGC action is as signals rise. A highest AGC SLP number means the AGC flattens everyone. AT SLP = 15 all signals above S3 are brought to roughly the same level. Heard one at a time, two signals - one at S3 and one at S9 will sound the same level. But, since AGC works on every signal in the passband, if there are two signals - one S9 and the other S3 appearing at the same time, the S3 signal will disappear because the AGC is knocking down the S9 signal to an S3 level and thereby also reducing the S3 signal to the noise. Using a less aggressive (lower) slope number will help but the dynamic range between and S3 and S9 signal is compressed. The core problem is the AGC starts at such a low level. Background noise alone on 80 - 40 is almost always more than S3. The suggestion is an AGC THR setting to allow higher than an S3 level before AGC action starts. That makes sense but does it start to degrade the high-end dynamic range of the radio? Are we in danger of overloading the intermediate amplifiers/mixers generating IMD and other unwanted issues? Seems like there is a balancing act here. Another way to accomplish this is to use the Attenuator and/or reduce the RF gain to reset our starting point so that the S5 signal at the antenna becomes an S3 signal at the AGC level and our AGC action doesn't really begin until S5. I would like the ability to switch in even more attenuation for high noise conditions. Can that be done through the software? Still I would like to try a higher AGC THR setting and see how it plays. The beauty of this radio is its ability to adjust to different conditions - one size does not fit all. Unfortunately, its also complicated. It has taken me three years to figure this little bit out. Comments? Do I understand it right? Buck k4ia K3 #101 In a message dated 12/9/2010 10:11:19 A.M. Eastern Standard Time, barry.n...@gmail.com writes: Thanks Don. I just realized that I can do some quick experiments to get my answer using an XG2's s3/s9 capability and noting audio level increase with AGC Off and then with AGC On and reducing RF Gain until same audio increase is accomplished. An aside to KE7X and W4TV: I too wish we could try experimental firmware that significantly raised the max AGC THR value. And to K6LL: Yes, I too fear loss of weaker signals 73, Barry N1EU On Thu, Dec 9, 2010 at 3:00 PM, Don Wilhelm wrote: > Barry, > > Without doing any measurements it may be difficult to say precisely, and I > would think there would be a bit of difference from one K3 to another. > > However, there is a quick and easy way to accomplish that - note that the > S-meter increases as the RF gain is reduced.
