Paul, I just made up the 3 wire cable that Jim described. It works perfectly. Remember, Jim could not get his to work with the rs422 converter. I am starting to believe the units have already been mo

Mine reads 1 PPS -4.7 ns. I'd say thats pretty good. No where do I see the words "Frequency Stable" on the screen. As far as how practical this is, I would say almost none. But I find the whole thing

It sounds like your headphones are 8 ohms. I suggest either adding a 100 ohm pad in series with each headphone or get 32 ohm headphones. The 100 ohm resistors can added right in the headphone jack. J

You need to tell the GPS receiver the antenna feedline delay in nanosecs. For free space, light travels at 11.8 inches in 1 nansecond. If the coax has the hard tpye insualtion material in it, its pro

You should normally have "monitor" turned off when you transmit. It can cause feedback if the noise is loud enough to get back to the mic. Also, when you speak on SSB, the ALC light should flicker on

I find the Orion AGC controls very interesting. The RF gain control in my opinion is not even needed on the Orion. If you set prog AGC, the threshold control works very similar to the RF gain control

The 500 hertz and 250 hertz filter correction allow you to tweak the center frequency that passes through the filter to allow for small variation in the true center frequency the filter passes. That'

The rx340 is a better SWL receiver than the Orion. This is because of the excellent sync AM mode on the rx340 and also because you have filters that go as wide as 16K on the rx340. If you want ultima
