Re: Sorry Re: [QRPLabs] Magnet Wire " of colour "
I've used different colours of craft wire from Hobbycraft and The Range in the UK. Not such a big range of colours and only two diameters, but it's soft copper and the enamel appears to be polyurethane and can be soldered-through. Watch out for the fumes. I think the brand name is Trimits. 73, John G4EDX Nottingham, England On 17 January 2018 at 15:19, Chris Wilson <chris@...> wrote: Hello Paul / Alan / Mike, |

Well I bought some earlier, was concerned it was just a coloured coating but looking at it in quantity it says enamelled, and soft, so here's hoping... ! Will report back when it lands. Thanks for the heads up Mike. Paul, great results on MF, very impressive!! Wednesday, January 17, 2018 Alan, I hadn't even thought about those things! I was wondering about 73, -- 2E0ILY Best regards, Chris mailto:chris@... --

I hadn't even thought about those things! I was wondering about thickness and durability of enamel. 'Enamel' is a rather generic term with regard to coatings on wires, and as we know not all are created equal. 73, Paul (currently working on mounting my prized U3S onto a rack panel along with some other bits of gear :-) On 01/17/2018 09:24 AM, Alan G4ZFQ wrote:

Thank you Hans!
That is what I thought, just wanted to confirm that it was probably static and not mis-configuration... Oh well... I guess I zapped it... will have to order a new one since all my other synth modules are in use... 73 Colin |
Re: Taking another stab at getting my 80m QCX up and running
I have a very nice old Boonton model 91H RF voltmeter. Do you think that would be useful for continuing the search for why the bandpass peaking signal is stuck?Mike, I do not know it but it is probably not sensitive enough. An alternative could be a normal RX, maybe with attenuator. 73 Alan G4ZFQ |
Re: Sorry Re: [QRPLabs] Magnet Wire " of colour "
What is the difference between enameled wire sold as magnet wire and enameled wire sold as craft wire? I've always avoided buying the latter, wondering if it is suitable for our purposes.Paul, I was going to ask, seen it before on Ebay etc. Is it soft copper, not hardened and springy? I assume any impurities will make no difference to conductivity and soldering. I also assume the enamel is not self-fluxing. That's a NO for me. I do not agree with scraping. 73 Alan G4ZFQ either works..Have a look at and? their? product code SPC-0320 |
Re: Sorry Re: [QRPLabs] Magnet Wire " of colour "
Good question Paul. My assumption is that a 28awg copper wire is a 28awg

copper wire. Were it anything else I would expect it to be described as a 28awg copper alloy wire. Easiest thing is to ask ray@... who sells the stuff. As far as I can tell, it looks, feels and solders just like enameled magnet wire. On 17 Jan 2018 at 9:11, N1BUG wrote:

Re: Taking another stab at getting my 80m QCX up and running
Alan,
I wondered about that. I keep letting the unfamiliar circuitry, ?P, Tayloe detector, etc skew my thinking... I need to get a handle on that. In the end... this is still an RF receiver and RF coming over the air is a very, very low level signal. ?V's not V's. It's not black magic. It's not smoke and mirrors... I have a very nice old Boonton model 91H RF voltmeter. Do you think that would be useful for continuing the search for why the bandpass peaking signal is stuck? I also have the choice of using an HP8657B to put a larger signal into the BNC but if I can chase ?V from the internal sig gen through the circuit I'd rather do that.? Technically not stuck btw. Yesterday it was reading 3 and 3/4 of the bars. A few days ago it was 2 and 3/4 of the bars and I haven't touched C1. This will end up being simple... I've built 20 or more kits of varying complexity over the last couple of years and every now and then a solder ball gets loose, a component is inserted incorrectly, and rarely, a component is bad or went bad because of the two reasons before this one. Not one time has it been the kit or the mfg of the kit. It's always been construction error... ? -- 73 NE5U Mike |

Re: Fast Simple QSO (FSQ)
(1) Your post was about about how interesting / useful the FSQ mode is. I agree, nothing wrong that, but you're post was
not a request for consideration. It was a post about how interesting / useful the FSQ mode is, and nothing more. It was only after it was questioned that you might have thought it could be of interest to Hans, maybe for future consideration. In which case.. (2) It's a QSO mode. How does that work with a U3 and no means of "on the fly" data entry ? I hope you can understand why I questioned the validity of the post. 73 de Andy |
Re: Taking another stab at getting my 80m QCX up and running
Hi Al, I have finally come to the point in life where nothing is obvious :)?
I pulled the resistor and it was dead on 120k¦¸. I see the square wave at the resistor lead come from pin 8. It's not there after the resistor.? "Continuity between the resistor and BNC center pin?" You know what... I don't think I checked that because I wasn't getting anything from the resistor connection on the board or the center pin of the BNC. I just checked it and it's good. I have looked over everything with a microscope numerous times and so far nothing obvious has shown up.?? There's a lot of stuff not getting done because of it but I can't walk away from this thing. Something will turn up... small solder ball causing a ground... something... -- 73 NE5U Mike |
Re: Power output questions
Hi Phil,
If the voltage is really 8,25Veff then?your output is 1,4Watt, not 2,5Watt. That is a little low. How did you measure the voltage across the dummy load? In my 20m QCX I used an oscilloscope (200MHz bandwidth) and measure around 46V peak-peak. That equals to 23/1,4142= 16,2Veff If you do the math then the output is 5,3Watt. 73, Martien PA4H |
Re: Fast Simple QSO (FSQ)
Not sure ,but was sharing something I thought was interesting.
After all...Han`s kits use modes that HE decides are relevant...and they come from somewhere right? I think Han`s chooses the modes that may or may not be relevant in his kits by popular demand or by how effective they can be for weak signal operation. Never know until people actually try stuff rather than act like sheep and follow the herd? Jim |
Re: Fast Simple QSO (FSQ)
Why not?? Some of the QRP Labs products transmit experimental modes, FSQ is experimental; maybe others would find it interesting.

Fast Simple QSO (FSQ)
Just for experimental purposes,my radio is setup for Fast Simple QSO (FSQ).
I have tried this back when it was first introduced and now wondering why it has not been used by many. I do see a lot of people using the mode for 40/30m.Today I am setup for 20m band 14104 dial testing with a friend while I leave for work today. Software is interesting and also curious how imaging compares to SSTV.So leaving it also setup to RX images. Software - 30/40m - I think this mode is worthy of further experiment.Feel free to call my station. Jim,N2NXZ 14104 usb |
