Its oscillating. Stop using it as you are transmitting outside the band - hence the high VSWR -- View this message in context: http://elecraft.365791.n2.nabble.com/K144XV-Strange-Readings-tp7573719p7573742.html Sent from the Elecraft mailing list archive at Nabble.com.

Re: [Elecraft] K144XV Problem

Might double check your xvtr settings in the menus and make sure they look right. If you have a recent good config backup of the K3 you can try restoring it. Other things to try: - Direct setting the frequency via the keypad. - If you have quick memories assigned to M1-4 keys to set 2M

[Elecraft] K144XV TX Spur

I did not see any threads on this issue, so here goes. I added the K144XV to my K3 several years ago. I don't think I have ever used it aside maybe from an FM contact to check it out. My new 23cM transverter has a 144MHz IF so I will now be suing the K144XV. While setting up the 2M power out, I

Re: [Elecraft] K144XV TX Spur

Are you sure the transverter is actually transmitting on the desired frequency also? Or is the PLL unlocked and on a semi-random frequency. I am thinking of the transverter frequency calibration process and if you are using the reflock feature you have it working right. -- View this message

[Elecraft] K144XV?

Is the optional 5V signal on the ANT3 center pin intended to be a T/R signal to a remote amp/preamp? I'm just trying to learn a bit about 2m stuff. What sort of external amps/preamps have folks found useful? Are the preamps/amps mast mounted, combined or separate? Thanks jim

Re: [Elecraft] K144XV?

Could be used for TR signal to a mast preamp or an external amp, but most of those I have seen need 12V by deafult. I suspect the 5V is more useful for transverter TR switching for simplified connections (fewer wires). You could have the transverters mounted on a tower making this method more

Re: [Elecraft] K144XV vs XV144

Not a comment on the K144XV vs XV144, but one about running eme. Use of a low-noise figure preamp is not optional for eme, so transverter sensitivity is less important an issue, though its nice if it is low. I use a DEMI 144-28 transverter with 0.8 dB NF (unmeasured) and 17-dB conversion

Re: [Elecraft] K144XV vs XV144

oops! meant to say: you can't work em if you can't hear em, but also true on 2m-eme if you can not hear me - LOL! I run ERP= 73kW on 2m-eme. Ed At 09:53 AM 12/16/2012, Edward R Cole wrote: Not a comment on the K144XV vs XV144, but one about running eme. Use of a low-noise figure preamp is

Re: [Elecraft] K144XV vs XV144

Both have a similar low noise, high gain front ends, Ron, and there is little to choose between them as regards performance. There have been several comparisons between the two on the reflector and a search on the nabble archive might prove useful. In your application, with an external amplifier I

Re: [Elecraft] K144XV vs XV144

The receiver sensitivity of the XV144 was good enough to do moon bounce with no other preamp at the antenna. Had about 120 ft of BuryFlex. JT65, and did not drive the power amp to more than 300 watts. I might have gotten more but a bias resistor in the amp was bad at the time. 73, John KH7T

Re: [Elecraft] K144XV (Urgent)

If you're trying to install it internally, you'll need the KXV3A. 73, Scott, N9AA On 8/30/12 1:20 PM, Vic Goncharsky wrote: Today K144XV safely arrived from FAIRS Hq., Floyd VA The European 144 MHz championship is held this weekend. Started to install the module and found no IF connectors

Re: [Elecraft] K144XV (Urgent)

Vic, The K144XV is the internal transverter, and you must have the KXV3A to connect it. If you call right now and beg them to ship it overnight, you may have it in time for the weekend. 73, Don W3FPR On 8/30/2012 1:20 PM, Vic Goncharsky wrote: Today K144XV safely arrived from FAIRS Hq.,
