[time-nuts] Re: Eloran long test from now to August or September.

[Shaun Merrigan]

Paul,

Good to know about the eLoran testing, thanks.  In that case, I am going to recommission an SRS FS700 that I put away years ago.  I will let the group know how it goes.

In the interim, I have tested a second 2100F and a couple of 2100R’s.  All achieved lock within minutes.   Interesting observation:  The Austron 2100F stays locked even with all my local noise sources turned on and the LORAN pulse being obscured (on the scope) by noise pulses.

Shaun,
OK interesting to learn. So with no display I might guess the data came out a GPIB or RS 232 port to something else.
I just sent an email eLORAN on till the end of the year and maybe longer.

Paul

Paul,

The 2100R is essentially a "headless" 2100F: The front panel consists of only four status LEDs.  The GRI is set by switches behind the front panel.  According to the 1988 Austron catalog, it was intended for use in applications where: "... a minimum of operator interface is desired."

Shaun now your just showing off. Chuckle Very nice.
What is a 2100r? Have not heard of that unit.
I have 2100 and 2100F units that I use.
These do a very good job of rejecting noise. Over the years noise in the VLF band has been going up.
It effects things like WWVB at 60 Khz and LORAN C at 100 KHz. First it was the CFL lights and now LEDs.
