[Elecraft] XG3 Extended Range (lower)
All, I have been looking at the XG3 as a alignment tool for old boat anchor receivers. However, many have IF strips at 455 kHz and lower. The XG3 stops at 1.5 MHz. Are there any plans to lower the bottom frequency limit to 100 kHz or lower ? Some boat anchors have a 60 kHz IF component. 73 Gene K1NR - Web mail provided by NuNet, Inc.

[Elecraft] Weak signal DXing on 2 meters

My email address is ulr...@steinberg.cc The wireless Internet infrastructure in ZS is excellent and I expect connectivity at least once a day until the middle of next week. At 21:00 I was actually pretty sure that someone called me, but it was too weak to get the call. But things seem to be improving, and the noise level is a little lower. The noise is a fairly constant crackling, and it can't be industrial here. I am running full blast on a power supply, but that is definitely not the noise source. Solar flux seems to be fairly low, so I don't think that trying a higher frequency band is any more promising.

[Elecraft] K3 LONG delay in TX after TXINH removed
I have TXinh sent to my K3 to ensure it doesn't transmit during initial keying or during antenna relay switching. In my setup TXINH is removed about 8 ms after the K3 is keyed. However, it looks like it takes the k3 about 450 ms or so after TXINH is removed for the k3 to make power output. This of course really messes up my cw output as it kills the first character. It also occurs with manual Tune from the front panel or with other modes, so not just on CW. I don't see menu items that would cause this. Anyone else seeing this? I 'think' this used to work, but I haven't tried old firmware to verify if my memory is correct. Since the 160 contest is tonight, I'll just pull the TXinh and live on the edge.

Re: [Elecraft] [XV432} LO Instability Problem
Thanks for all the help and comments received so far, on and off reflector - I have to say the responsiveness and quality of help on this reflector is second to none! To summarise: 1. I have tried detuning L4, along with L3 and L5. L4 is very sensitive as is probably to be expected, L3 and L5 somewhat less so. The most stable point of L4 does seem to coincide with the peak in voltage at TP1, and detuning L3 and L5 doesn't seem to make much difference. The problem is that the voltage at TP1 can easily reach 4v or higher, and the LO is definitely less stable if I detune it to keep the voltage below 3v. 2. Is a voltage well above 3v at TP1 a problem? It seems to be just a detector diode circuit on the output of the LO, so I presume a fair amount of variation is to be expected. 3. The crystal seems mechanically stable in that tapping it doesn't send the frequency all over the place, but it is highly sensitive to being touched, which I assume is heating effect, 4. The biggest single improvement was a suggestion to ground the can of the crystal. This is something very familiar to any K2 builder. I grounded the crystal can, K2 filter style, to the oven -ve pad, which was the closest ground point. Huge improvement. The frequency jumping has gone, although there is still significant drift, even long after warm-up. 5. I then tried readjusting L3, L4 & L5 to see if detuning the voltage to about 2.5v at TP1 helped now that the oscillator seemed more stable. This seemed to be a backward step as the LO lurched down about 10kHz in frequency, started to drift back up, but then actually stopped oscillating. Restoring L3, L4 and L5 to the point where the voltage at TP1 peaks - about 4v - seems to be the most stable point & the LO starts up fine. From switch on it drifts about 3kHz low, then as it warms up, it starts to drift HF until about 3 or 4kHz above the switch-on point. 6. If my unit is normal, the oven would seem an essential. As I want to use the transverter on SSB, I can't really live with a drift range of 7kHz! 7. What is the view on grounding the crystal can? It does seem to help tremendously with the stability (and I mean the 'crystal mode' stability, just to differentiate from drift). I think my next step is to order the oven (I'm going to have fun fitting that now I've grounded the can!) & possibly another crystal. 73 Ian G4FSU On 25 January 2013 14:01, Don Wilhelm wrote: > Ian, > > Two possibilities occur to me.

Re: [Elecraft] [XV432} LO Instability Problem
Ian, Does the LO frequency jump if you tap the crystal's can using a plastic "rod" such as an alignment tool or pencil? If it does, and if all of the soldered connections in the LO's circuit are sound, the jump and drift are most likely caused by some "mechanical" fault within the crystal assembly itself. The only cure in such cases is to replace the crystal. 73, Geoff LX2AO On January 25, 2013 at 9:40 AM, Ian Greenshields wrote: The LO on my XV432 transverter seems to be very unstable.
