I've been using my Junker for about 40 years, I've tried all sorts of other keys but still go back to the old Junker, it's so precise it is a pleasure to use.

I wouldn't take too much notice of those speeds indicated on the RBN, they always seem to return speeds a lot lower than what the speed actually is, particularly hand sent code on a straight key. My measured speed on a straight key can be 26WPM but considerably less as measured by the RBN maybe around 18WPM, after all, its just a machine.

If I only answered CQs sent at or below my comfort level, A) my speed would never improve, and B) I would rarely be able to work any DX. The flip answer, of course, is "Call CQ yourself." Then, in theory, you'll be in control of the speed. It probably won't stop folk answering your CQ at twice the speed, though. I say "flip answer" because I find calling CQ is about a thousand times harder (give or take an order of magnitude) than answering CQ, but that's a different issue... 73, Rick M0LEP That's interesting you say that Rick, I find the opposite myself, maybe the subject of another thread rather than this one. |

Can't appreciate that. May be kind of music but interpreted as Morse code it is really bad. UU22UU or whatever is one large bunch of dots and dashes without a letter space, so multi interpretable. There are no word spaces in the text only letter spaces, and _wire_ is not sent because there is no letter space between w and i and hence it is possibly wi but also possible ez or ad or pe So making music is one thing but doing that kind of entertainment by mutilating Morse code is another thing, that makes such a kind of fist very hard and tiring to copy. Te He, you've missed the point, it's not meant to be readable morse code. |

Let's start again, for four tubes the max allowable dissipation is 260W at 1500V so with 125ma the tubes are within spec at 187.5W but with 175ma the total dissipation is 262.5W which puts the tubes slightly above their rated dissipation, so yes, I would say it is a bit high.
I have had a look at the manual and are you sure the tappings are correct? 241V should not make that much difference, if your line voltage is the same spec as ours it is plus or minus 10% of the nominal or declared voltage anyway.

I agree with Mike, I think your levels are too high, once you get those sorted out then you can start looking at the rest of the set-up.
I think you really do need to get hold of some test equipment to measure your levels, an oscilloscope would be useful if you can borrow one, a lot of amateurs use them and if you are not sure how to use them I sure they will gladly show you. You can't really use the ALC meter, that is quite meaningless for what you are trying to achieve.

Can you describe the noise? Is it something like a humming sound or a hissing noise, if it is a hissing noise it sounds like the gain into the rig needs to be reduced, if it is the former then it could be what's called a hum loop which might take a little more to get rid of.

I have tried to use the keyer in my K3 and I find I can't get on with it very well at all. Like Bob I've got the K1EL keyer and I find it's wonderful, I can set it up just like my old home brew keyer I used for about 20 years.
Having said that, I find I use the straight key more these days for two reasons, it's more of a challenge and the elbug sounds too much like a computer sending for my liking, I tend to use the elbug if I run out of speed on the straight key at more than 20WPM.

What about hanging it partly outside and partly in the loft or attic? I use a 75 foot doublet with one leg in the loft and the other leg out down the garden (back yard) at about 20 feet over the ground and it works great on all bands. You don't have to worry about the ground if you are using a dipole, because it is a balanced antenna.
That is the quickest way to learn is to use it on the air, it is hard work, and you will wonder if it is all worth it, but trust me, it is worth it in the end.

Good for you, well done, keep up the pratice so that I can have a QSO with you soon.

eHam Forums / CW / RE: How to answer a CQ
|

How do you answer a CQ in cw ? Most times when I hear someone calling CQ, I simply send K3TN back once or twice depending on conditions. I figure the station calling CQ already knows his call - no sense sending him something he already knows. If the frequency is crowded and there might be some doubt who I am coming back to, then I will send his call de my call. If he comes back to me and sends only "5nn BK" I do the same. If he sends "RST NAME" I return "RST NAME QTH " to see if he wants to talk further and so on. Easy way for me to match his intent without sending a lot of unnecessary characters out into the ether. 73 John K3TN That's all very well John, but I have had situations where I have been called by a station just giving their call and I've trundled on giving the calling station all my details only to find he is not calling me, but someone else, maybe a DX station 1KHz down. I don’t use full break-in all the time, so who is in the wrong here? It makes you feel a right plonker when you realise you’ve made a mistake because the calling station hasn't used your call. |
