Does it REALLY matter if it doesn't pass Sherwood muster?

    Does it really matter what HF receiver you use if all you operate is CW and the receiver has earned a dismal Sherwood rating?

    And why if it matters so, do lots of CW buffs use ancient gear to operate CW? How does that happen without Sherwood's blessings?

    What about home brew or real cheap kits?

    Why doesn't Sherwood rate the cheap CW rigs like the NorCal 2N2/XX or Hendricks QRP Kits and other like kits/radios?

    And since he doesn't, why does anyone even bother to use them at all? I mean I thought a positive Sherwood rating was all that REALLY matters. Sure seems it considering what you read today with the weight given the Sherwood/Holy Grail tables.

    That said, the FT450D and other much newer advanced radios than the Drakes should be banned from US sales since they take second and third fiddle to any Drake made.

    No I don't own a Yaesu---I sold it after reading the report---- according to Sherwood the only radio worth owning is old Drakes, of course they sell kits to make sure of it-----lol

    Should I peruse eBay until I come upon a Drake station?

    Bonus Question--- AND why do some hams operate CW using a fifty dollar kit and six hundred dollar special made paddle from Italy or someone's basement?


    kivb-3 yea, I see things differently

    not that many people operate with the Italian specials.

    Sherwood is like reading consumer reports, do you buy everything based on their analysis?

    Because CW ops live at their fingertips.

    I think a lot depends on how you operate. If ragchewing is your thing you can use most any reasonable rig. Serious DXing and contesting is another story. What you can afford may have a lot to do with it too.
    I think it is just as important to have a rig you would really like to have and use. The best rig out there isn't worth much if it doesn't compel you to get on the air and use it.

    Expensive keys are easier to sneak into the house than a new rig!!

    Why place so much emphasis on what one "expert" said?

    A bit of thought on the part of the equipment buyer is all that is necessary.

    If you find a radio that fits your budget and needs, then buy it and be happy that you have one of whatever it is.

    Sure there are probably some out there that are better than others, but are you really going to worry about that?

    FWIW, and that's not much, I've purchased a few rigs in my day. Not many, but they all seem to work FB and do what I need them to do and I've never read the "Sherwood report". Heard about it, yes. Read it? No. I still manage to get on the air.

    Funny how that all seems to work out.

    You can do CW ragchews with just about anything. An Icom IC-718 with the 500hz filter will do that. So will an FT-450D, or TS-480, or any rig you can get a 500hz filter for.

    Just don't expect any of the above radios to survive in contest situations without overloading the front end.

    +1 again with a hearty "heh, heh, heh" to go with it [​IMG].

    Agree with KJ3N. It can matter, and sometimes does.

    This weekend we put W8LRC on for the MIQP. There were problems, first being a local noise level of S9 to +20 depending on what rig was used. No rig we tried was immune, so we ended up using the beam on 40 SSB and doing without 20 for the time being. Needless to say, we need not be worried about being in the top half, not with a tenth or less of the numbers we were hearing, but it ended up being fun.

    Later, when later the local RFI noise got better, and we went to 80 and 40 on the sloper, the club’s TS-450 couldn’t hear a thing, and even a Jupiter I brought in needed its attenuator to get rid of IM-generated background noise. Using the spectrum display, I was able to demonstrate this visually to another op who came in while 80 was really hot. Without attenuator, even the Jupiter had problems pulling out all but the strongest signals, and the 450 was swamped.

    Not sure my Omni V, which is noticeably quieter than the Jupe, would have been much better. My old Corsair II might have been, but it’s sick at the moment. It’s for conditions like this that really good IMD performance is needed, and the more modern, better performing rigs are some 20 dB better (or more) than these in Sherwood tests. MOST recent rigs aren't that good, so for contesting, yes, one needs that kind of performance.

    It turns out the TS-450 we used at W8LRC has a quirk that makes its IMD shortcomings even more apparent than they would be in other rigs, for signals farther from the filter passband. In the ARRL’s 1992 review’s words, ”If we have only out usual test results, these receivers [NB: TS-450 and TS-690] would appear to be much less usable than they really are.” It seems that -- in the contest environment -- the 450 is only as usable as it appeared then.

    many air craft / military radio , I have heard they need to receive weak signal while near by stations is transmitting 20 kHz and 100 feet away. I am lucky that I don't have any ham live close to me, so my cheaper radio don't get overloaded. once, I had a Ham lived 200 feet away, every time he transmit, it wiped out entire band of my receiver.
