[Elecraft] Sub Rx Success!
Just completed the installation of the Sub Rx in K3 325! Very pleased to say all went well and it's working just fine. Need to learn how to drive it now.

[Elecraft] K3 Speaker cabinet resonances
Has anyone found a solution to the cabinet buzz from the K3 internal speaker? I've not used the internal speaker until recently on my K3 and now find I have annoying cabinet buzz around 450Hz and 600Hz, not so good for CW! I haven't tried any damping as yet and just wondered if anyone has managed to cure this cabinet resonance. 73,Deni F5VJC K3 325 -- View this message in context: http://n2.nabble.com/K3-Speaker-cabinet-resonances-tp1306081p1306081.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Speaker cabinet resonances
Thanks to all who responded to this question. Having looked into it further it seems I have a combination of cabinet buzz and a defective speaker. I removed the top panel of my K3 did tests and found the most bothersome buzz at 600/610 Hz is still present with the top panel detached. Checked screws all tight (not too tight) and various other mechanical tweaks but can't clear it. So I guess I will email Elecraft support about a possible replacement speaker. This is a very small annoyance in an otherwise fine radio, and it's just come to light now because I always used external speakers or headphones until now, having reduced my K3 to bare bones due to an impending move of shack, I'm listening to it's internal speaker. 73, Deni F5VJC K3 325 Deni F5VJC wrote: > > Has anyone found a solution to the cabinet buzz from the K3 internal > speaker? > > I've not used the internal speaker until recently on my K3 and now find I > have annoying cabinet buzz around 450Hz and 600Hz, not so good for CW! > > I haven't tried any damping as yet and just wondered if anyone has managed > to cure this cabinet resonance. > > 73,Deni > F5VJC > K3 325 > > -- View this message in context: http://n2.nabble.com/K3-Speaker-cabinet-resonances-tp1306081p1307647.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3USB ??
I bought a K3USB when I ordered my K3, quite now some time ago... I have never used it as I've been using a standard serial port with my K3. Now I want to convert to USB and of course I've lost the K3USB device. I can't even remember what it looks like! Can someone describe, or better still send me a pic of the K3USB so I know what I'm looking for? I have vague recollections of a silver screened cable with a clear outer sheath...?

[Elecraft] K3 for me...
Hi Julian, well said! My views exactly as another in EU with an early K2. Good to have it affirmed by you. I too have been hoping and waiting for just this radio... it's a must have, and my order is in too! 73, Deni F5VJC / GM3SKN K21188 I'm totally gobsmacked by the K3. I never imagined that the K3 people have fantasized over for years on this reflector would actually become a reality, in kit form too, at such a reasonable price. The moment I saw this, as when I first read about the K2 back in 1999, I knew this was one radio I just had to have. From this side of the Atlantic, at $2 / £1 exchange rate, it looks very good value indeed. I'm hoping that the modular kit will qualify for import duty exemtion as well. I have decided to get my order in before one of the UK dealers asks for exclusive UK distribution rights and we all end up having to pay twice the price.

Re: [Elecraft] Modern battery for K2
Hi Sverre, I am still using this battery external to the K2. It is very convenient as it just sits under the rig and easily connects to the K2 power jack with the attached cable provided, no mods required. Yes the switch needs to be ON both for charging and when in use as a supply for the K2, and yes the LED is ON in this state so will no doubt in time discharge the battery. As it seems very convenient like this I decided to leave the battery external. I have now purchesed another Na I find them to be excellent and much better than the heavier limited Ah SLA batteries. 73, Deni F5VJC On 7 August 2013 16:22, Sverre Holm (LA3ZA) [via Elecraft] < ml-node+s365791n7577478...@n2.nabble.com> wrote: > I wonder what resulted from this.

Re: [Elecraft] Static rain ?
Very interesting Geoff, thanks for the comments. I've deliberately not installed those front end diodes in my K2. As to the rain static, we've had very severe rainstorms in France as I believe you too have experienced in the UK and this problem with rain static I have never heard so bad, however this is a relatively new antenna installation for me. The vertical element is constructed from a 42' length of coax using the braid as the radiator to provide a fat wire, this radiator is suspended "inside" a Spiderbeam fiberglass pole so is in no way in direct contact with the rain. I used to use a butternut vertical (exposed aluminium vertical radiator) and didn't notice rain static quite like this. Yes my feeling is the resistor bleed would be better than the choke for the reasons you mention, still, I've just been out and measured the resistance from the antenna to ground and of course it reads zero Ohms, through the ATU I imagine so I don't quite see why I need a further static bleed path, but I'll try it anyway. Good to hear your K2 is a survivor, I've not had that horror, something I dread, however at the base of my antenna is a spark gap arrestor and then the auto ATU so...fingers crossed. 73, Deni F5VJC Geoffrey Mackenzie-Kennedy wrote: Deni, My suggestion is that you use a resistor and not a choke. A choke at some frequencies will become a series resonant L-C 'tuned' circuit, and it is quite possible that the choke will resonate in or close to one of the bands that you use. If that is the case you will loose transmitter power heating up the choke, likewise the strength of received signals reaching the receiver can be reduced. For static bleeds I usually use 100k 2w carbon resistors, the old fashioned type not carbon film, because the resistors *must* be non-inductive types. My K2 survived a lightning strike to my 40m beam, but I think that the combination of a coax spark gap out in the garden and an underground coax feeder with 'surge loops' took out much of the sting. Back to back diodes for protection against overload can create all sorts of intermodulation problems if the diodes start to conduct, and for those of us in Europe who share 40m with BC stations and using receivers which cannot cope, overload is a problem but there are solutions. Please contact me off list if you are interested. 73, Geoff GM4ESD - Original Message - From: "Deni" <[EMAIL PROTECTED]> To: Sent: Saturday, December 09, 2006 9:52 AM Subject: [Elecraft] Static rain ? I have recently been plagued by rain static on a new vertical antenna, this is a 42 foot vertical fed at the base through an SG230 auto tuner, and used on all bands. It seems I need a static bleed of some sort, a choke or resistor. What is the best component to use in an outdoor environment? My junk box RF chokes look rather puny for this application, the typical small 2.5mH RF choke. Would a physically large, say 1 Meg resistor be more suitable ? I thought the auto ATU would in itself provide a static bleed path, but apparently not. Is the K2 prone to front end damage due to this static charge? I do not have the back to back diodes fitted (to prevent huge signal overload) Any thoughts, how have you solved this? 73, Deni F5VJC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 Toroids Latest?
Hi Vic and all. I have kept my K2 (1188) up to date with all the A/B mods, however at times I see references such as the one below about T7 where a toroid may have been changed from the original windings to a revised spec. Are these documented anywhere, which toroids are now different and why? Thanks, 73, Deni F5VJC / GM3SKN K21188 = It looks fine, although I would move the two wider filters a bit to the right. There looks like about 6-8 db difference in attenuation between the widest and narrowest filters, which is probably on the high side of normal (although this tends to vary). I see about 4 db on mine, which is #709 but has had the crystals replaced and T7 rewound to current spec. I would be interested in knowing how much difference in attenuation others are seeing. I know that K1JD has an ANCIENT K2 (field test vintage) which has zero db difference! -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
