Re: [Elecraft] XV144 Crystal Oven

David, Sadly, that crystal oven is no longer manufactured. I am certain there are other crystal ovens available, but you may have to cobble something together because the pins are not likely to fit the XV144 board. The easiest solution is for someone to step up and tell you he has a spare.

Bob, I use the XV144 here w/ my K3, and my Config:xvtr power is set to L1.00, and that will easily drive the XV144 power LED's into the red. I suspect the issue is not with your K3 settings, but rather with the jumpers inside the XV144 and the setting of R22 that acts as an input attenuator.

Re: [Elecraft] XV144 help please

Bob, It did produce 20 watts with 1 mW input when it was here. And the LEDs are calibrated to what *my* wattmeter was reading. My wattmeter is checked periodically against a calibrated 40 dB power tap and a W7ZOI Power Meter (homebrew, but calibrated). So remove the top cover, and try

Re: [Elecraft] XV144 - does it power spike

Most of the YaKeIc I've ever worked with have this issue. Anytime you use ALC to control the power output there is a chance that that can happen if you are turning the power way down. When the rig is first keyed, there is a window before the ALC voltage is set properly that can allow this. It

[Elecraft] XV144 - does it power spike

Having just been told the reason I've blown the finals in 2 (possibly 3) 2m apps is because the FT-857 gives a spike of 50w when you PTT (regardless of what the Tx power is set to on the FT-857) before it settles down to the power set in the menu... Can anyone tell me if the XV144 does this -

Re: [Elecraft] XV144 - does it power spike

David, The XV144 does not do that on its own. If you are driving it with a K2 or K3, I know you will be OK, But if you are driving the XV144 with something else, be certain that it does not produce a poweer spike in the 28 MHz output. 73, Don W3FPR On 12/20/2012 1:07 PM, David Ferrington,

Hello David, I have the internal transverter that is similar to the kit that you have and I do not experience any spike at commencement of transmission. 73 Peter G3SMT __ Elecraft mailing list Home:

[Elecraft] XV144 XV50: LED brightness

I have noticed a significant difference in the brightness of the LEDs in my XV144 and XV50 transverters. Sorry there are no serial numbers, but my XV144 was purchased in July 2004 (with Manual Rev.B, November 7, 2003). My XV50 (now modified for 70MHz) was built according to the Assembly Manual,

Hello everyone, I am starting to gather equipment for an attempt at moonbounce. I would like to find an XV144 2 meter transverter for the station. I know that Elecraft has many and it would be great to build another but funds are limited. If anyone has an XV144 that they are not using and

[Elecraft] XV144, protection against high SWR?

Hello, I just wondering if the XV144 has some kind of protection against high SWR? I have burned C44 in XV144, twice in very short period. First time when I using XV144 to tune input circuit of my amplifier, and second time I forgot to switch input relays when testing and the XV144 was without

Re: [Elecraft] XV144, protection against high SWR?

There is no high SWR detection or protection in any of the XV transceivers. If operated into a high SWR, yes, high RF voltages will exist in the Low Pass Filter which can easily exceed the voltage rating of the chip capacitors. 73, Don W3FPR On 4/9/2012 4:14 AM, Samir Popaja wrote: Hello, I

[Elecraft] XV144 details

I am about to jump into the world of transverters with the purchase of an XV144 to pair with my K2. The K2 is a very early S/N but has had 'most' of the updates. I would like to make the use of the transverter as painless as possible. So I checked out the 60m mod page on the Elecraft
