In my study of the TX Noise produced by current transceivers, I noted the significant advantage enjoyed by users of dirty rigs by pushing other stations away from their TX frequency, and making it di
Hi Jim Hope the offender wasn't using one of the FT-1000's you sold him :-) 73 Tom W7WHY Yes, I'm saying that users of these dirty rigs need to replace them with cleaner ones. In 2008, I sold a pair
And just where should all these "less than desirable" rigs end up? They are certainly going to be put back on the air someplace. Maybe they should go into a landfill? It sounds like another "Cash for
you make me curious. what would i be listening for? i know if i mistune my arc5 vfo, or some of my power amps, i can get birdies up and down the band, but my stodgy amps (833, 810 tubes) i can't get
You only moved the "problem" by selling those awful radios. If you were seriously concerned you would have destroyed them. :-) 73, de Hans, K0HB "Just a Boy and his Radio" 73 _______________________
To the contrary, I want to ask Elecraft to give me a menu option to reenable the old FSK firmware for those times when I want the elbow room on RTTY. Kidding. Sort of. 73 jeff wk6i -- Jeff Stai ~ wk6
I wonder if this ham gets a commission from Elecraft? Maybe the K3's he has needs a better front end so they are not overloaded by nearby hams. Maybe W7DRA and I need to get on using Heath DX-100's.
I don't know about those radios by my old rig, FT1000MP, had pretty bad key clicks. I believe that most of them do. I had a couple of guys bring it to my attention and got a mod done to eliminate the

Very few signals sound dirty on either of my K3s. However, there are a couple that sound dirty and are from well known contesters. Looking at the signals on the P-3 is pretty enlightening and general
Carefully study 97.307 (a), (b), and (c). They are FCC RULES, actually, and as I read those paragraphs, a ham using those rigs would be in violation. 73, Jim K9YC ____________________________________
Dave, These rigs are fine (well, acceptable) when they are used barefoot at 100 W. But there are quite a few contest stations that run amps (often exceeding 1500W) and then they indeed have advantage
Has anyone actually tested the ftdx-5000 since the latest firmware update which was supposed to have resolved this issue with the wide cw signal? Rich Hallman, N7TR Ex. KI3V, N3AMK, HL9RH, A92FN ____
Actually, a much sensible direction to take this is not to punish the dirty rigs but to reward the clean ones. The hard part is to get some sort of pre-registration set up with the contest authority
If I had one, I could measure it, but it would be hard to compare my results to the ARRL Lab results. A more interesting question is, what does Yaesu say they changed? Note that I leaked an early ver
It is true that some rigs (depending on how they are operated) can produce signals that appear wider than normal. Can you think of a way to express this in technical terms rather than using a K3 as a
I want my blockers, running backs, and even receivers to be as big as humanly possible (and some are). WIDE shoulders and beefy bodies. But it could be that someday NFL will be flag football and CQ W
I've often thought that a bit of SDR software might be able to accomplish this. My thought was to use a sliding cursor on a spectrum (panadapter) display to center on a particular signal, "capture" t

Hi, Yes, comparing against one rig is difficult, and we are lucky the top rig in the list is rather affordable. What would it be if the Hilberling PT-8000A was blowing everything else. One the other
There are several problems in judging a dirty rig Dirty by whose standards? The FCC publishes required levels of operation for several aspects of radio performance but is silent on matters like phase
