Re: [Elecraft] Signal source for KX3 temperature frequency calibration

For those considering using the excellent dual output Leo Bodnar GPSDO, be aware that you cannot select certain combinations of output frequencies. I have the dual output unit and it can be set for 10 MHz on one socket and 1 MHz on the other, which was ideal to drive my old Racal counter at 1 MHz

Re: [Elecraft] Signal source for KX3 temperature frequency calibration

Indeed.  I have one of each.  Two of the Minis is probably a viable alternative unless you want two locked signals with a prescribed phase difference.  Of course then you need a splitter on the GPS antenna and two USB ports.  One problem with these is that they're TCXOs, not OCXOs.  They can tak

Re: [Elecraft] Signal source for KX3 temperature frequency calibration

Agreed, but as I already have the single frequency version, it will be cheaper too just buy another one. 🙂 73, Alan - G4GNX > On 14 Jun 2023, at 22:38, Wes wrote: > > The Leo Bodnar two-channel GPSDO should give you both frequencies, although > setting them is really clunky. The promised

Re: [Elecraft] Signal source for KX3 temperature frequency calibration

The Leo Bodnar two-channel GPSDO should give you both frequencies, although setting them is really clunky.  The promised revised software never materialized. Wes  N7WS On 6/14/2023 11:27 AM, G4GNX wrote: It’s true that both rigs *can* use a 10MHz reference, but the far better way to run the I

Re: [Elecraft] Signal source for KX3 temperature frequency calibration

It’s true that both rigs *can* use a 10MHz reference, but the far better way to run the IC-9700 is by using an injection board which pulls the onboard TCXO from the GPS reference at 49.152MHz, instead of using the 10MHz input which is only checked periodically. The only disadvantage is that 2 d

Re: [Elecraft] Signal source for KX3 temperature frequency calibration

Why not just split the signal to both radios since both use a 10MHz reference? Or are they very far apart? Björn SM7IUN On Wed, Jun 14, 2023 at 4:34 PM G4GNX wrote: > AFAIK Leo ships Worldwide (perhaps not Russia)! > > It’s an excellent device and fully configurable. > > I use one on my IC-9700

Re: [Elecraft] Signal source for KX3 temperature frequency calibration

AFAIK Leo ships Worldwide (perhaps not Russia)! It’s an excellent device and fully configurable. I use one on my IC-9700 and it works flawlessly. I’m considering buying another one for the K4, because I’m a bit OCD. 🤣 73, Alan - G4GNX > On 14 Jun 2023, at 14:40, Björn Ekelund wrote: > > I'

I'm not sure they ship to the US but I use this to calibrate all my radios. Björn SM7IUN On Wed, Jun 14, 2023 at 2:31 AM Hank via Elecraft wrote: > The TinySA ultra has many uses in the ham shack. > > I

Re: [Elecraft] Signal source for KX3 temperature frequency calibration

The TinySA ultra has many uses in the ham shack. It has a nice frequency generator function including AM/FM modulation plus some nice spectrum analyzer features only found on much more expensive devices. Hank K4HYJ > On Jun 13, 2023, at 12:59 PM, John Harper wrote: > > tinySA Ultra: > htt

I have an XG50 that you are welcome to borrow for the price of postage. Eric KI7LTT On Tue, Jun 13, 2023 at 9:11 AM Bill Adams wrote: > > The XG50 signal generator is no longer available and I’m in need of a > stable signal to do the extended temperature compensation procedure on my > KX3. I re

[Elecraft] Signal source for KX3 temperature frequency calibration

The XG50 signal generator is no longer available and I’m in need of a stable signal to do the extended temperature compensation procedure on my KX3. I remember a discussion about using the K3’s external converter output but cannot locate any details. Any suggestions? Bill AF4B Sent from my i
