Re: [Elecraft] ARRL Field Day
Bill's message brought a question to mind: I am relatively new to PSK (operate mainly CW), but after receiving my KX3, started to take an interest in it. After listening for some time, I became curious as to why some hams were giving out poor IMD reports and verbal reports of You are splattering all over when I wasn't always seeing the same thing. Some folks were just downright rude with their reports. I realize that different software packages may give different IMD measurements, but a few were grossly different. There seems to be a lot of information about getting things set right on the transmit side, but not so much on the receive side. Certainly, making sure the RF gain is down is important to keep all the amplifier stages linear, but little is ever mentioned about AGC. It is similar to ALC on the transmit side, and is certainly non-linear if you are operating near or through the threshold (not sure I described that very well). For those reasons, I would think that receiver AGC could also generate the IMD that these stations are seeing causing them to give out poor reports. Admittedly, reducing RF gain helps to keep you from activating AGC, but seems like maybe turning AGC off before giving a signal quality report would be advisable. Some of the comments I have heard have kept me from jumping into PSK with both feet. They take the fun out of operating. The website http://rsq-info.net/ has been most helpful, but I don't recall seeing any mention of AGC, so maybe I am completely off base here. I am really a PSK novice, so any comments would be appreciated. I haven't run any digital modes (except cw) since I sold my Model 19 TTY. Back then, we didn't have an easy way to measure IMD or even see the sidebands that you see on a waterfall, and you almost couldn't hear the audio over the clatter of the Model 19 once you had your signal sync'd up. We just operated.

Re: [Elecraft] ARRL Field Day
Mark, I have to admit, before I started using WINMOR, I didn't know the information I'm about to tell you. I was probably splattering all over the place too. Also, I think this only has to do with AFSK not FSK (someone correct me if I'm wrong). I know you asked about the AGC, but *usually* this has to do with ALC of the transmitting station. Splattering *usually* (I say usually because *always* is too definite) has to do with TX audio gain. On both the KX3 and the K3, you want to watch your ALC. Adjust your transmit audio (another reason to use an external soundcard for AFSK modes and not rely on the rig to do it IMNSHO) so that your ALC shows four bars with the fifth bar flickering (most other radios require *no* ALC, but the Elecraft rigs are different due to where their ALC actually kicks in). An example of when this is not the case is another PSK station within a mile or so of your station. Splattering is not dependent on output power of the rig. I can (and do on WINMOR) transmit 100W and have a clean signal by adjusting my ALC so that it is four bars with the fifth flickering. I have seen folks running 20W and be all over the place. I worked a station on FD who was all up and down the passband with artifacts. I kindly told him that he was splattering and that he needed to adjust his transmit audio - within a few minutes, he was clean. No one need be an alpha-hotel when it comes to correction. I will say that in AFSK modes, if you get much off center of the passband (about 1500Hz), you will need to adjust ALC again. I have started to just practice turning the VFO. This also helps with the 500Hz filter; especially if I want to tighten it up a bit. On the KX3, this seems worse than on the K3 and I don't know why. I don't really use the KX3 for digital modes because of having to constantly swap out cables and no monitor of my transmit audio. I just turn down the power on the K3 and let 'er rip. In all honesty, when I find a lot of folks moving to a mode, I start moving away from it. I rarely work PSK31 anymore. I prefer Olivia (8/250 for weak signal). I got on the JT65 bandwagon just long enough to get my WAS and I haven't operated it since. Yeah, that's selfish I know, but I got tired of folks all over the passband and outside the passband interfering with other operations that were/are not JT65. It seems a lot of folks get a license and forget about the part of the rules that say only use the amount of power necessary to complete the contact and don't interfere with others. I did work PSK31 on FD, but I started out on RTTY and really enjoyed it. I may actually start using it again since it seems folks are moving away from it on a regular basis. That being said, I still like CW and operate (when I operate) mostly in that mode. Sorry for the long dissertation (I have a friend who calls me verbose). I have tried to make sure that any of my signals never interfere with anyone else. If I'm on the air and a nearby signal comes on, I usually just go to another band. He's a friend of mine and he's doing nothing wrong, we're just too close to each other to operate except into a dummy load. There is plenty of space and lots of bands to work. I may even add the 6M wire to my hexbeam and start going there for some VHF stuff. Who knows. The hobby is vast and looking for explorers and adventurers. 73, Joel - W4JBB On 6/27/13 1:45 AM, Mark Petiford wrote: Bill's message brought a question to mind: I am relatively new to PSK (operate mainly CW), but after receiving my KX3, started to take an interest in it.

Re: [Elecraft] ARRL Field Day
I also think phase noise is the likely culprit. A look at the field day writeup in their club newsletter shows no K3s or K2s in their photos. The only rig mentioned specifically was an Icom IC-756PRO3 for their GOTA station and the photographs show a 3 element beam. In response to an email they said they were running 100 watts on all of their transmitters. I think 100 watts with a standard transmitter on PSK might be in the worst part of the performance envelope. My guess was that their signal might have been as much as 8 dB stronger than that of our nearby CW station. They were about 1/2 mile from us and our CW and digital antennas were about 600' apart. I calculate 13dB for the power difference, minus 12dB for the inverse square law, and a wild guess of an additional 7dB for the antenna patterns. They were a lot closer in frequency than our CW operation (1 KHz vs 20-60 KHz) which doesn't help.

Re: [Elecraft] ARRL Field Day
The Field Day Operations for WM4AA and NY4G was up on Mt Pisgah in a campground near the Blue Ridge Parkway in NC at an elevation of approximately 5000 ft (give or take a few feet). The rigs were a couple of KX3's running on external SLAs. It was also our first opportunity to use the pneumatic tennis ball antenna launcher I built and 70 ft high trees were a piece of cake. The weather was wonderful - temps in the low 70s in the middle of the day and below 60 at night on Saturday and the views were spectacular. The antennas were a full size twin lead fed dipole (a modified G5RV) - tuned by the KX3's without even blinking from 80m through 10m, a 10-20-40 ParEndFedZ and a 15m monopole. I took advantage of the IQ output of the KX3 and it was SP all the way on the NaP3 panadapter. WM4AA employed about 85% SP and 15% calling CQ. We had a 20w solar panel to help keep the batteries fresh. There were absolutely no problems with the rigs and the KX3's performed marvelously. It was our first Field Day with KX3s. WM4AA's was brand new - just received a few days before - SN ~4500 and mine was built after last years FD in August 2012 (SN 1211) and FD 2012 was done with a couple of K2's. Kudos to Elecraft for engineering such a fine rig for QRP Field Days.

At my home station, I have run 5 stations at 1.5 KW (HF bands) and had to deal with problems you only can read about!! Amazing what happens when you run HP, antennas pointed everywhere and all kinds of questionable cable/connector issues. This year, our 3 el. 20 M monobander generated some broadband noise (tested before FD began) and it was resolved when we replaced a few rusty screws, etc. Hey, its all fun!

Works well. I recall a few times of testing, no noise from SSB while listening on the CW end of the band - nice!

One station, say, on 20 and the other on 15 during daylight, then one on 80 and one on 20 or 40 at night. In my case, I was solo 1B battery so it didn't matter. :) 73 de Ray K2ULR KX3 #211 On Jun 24, 2013, at 12:12 PM, Scotty Long wrote: ARRL Field Day...

I shut down late afternoon and departed the area for cold air and drink...
