Hi Dave,
That is an issue that needs to be re-emphasized. You can't read
the EPROMS in a 7L18 without using multiple rail supplies. +5V
alone won't do it.
Also, the 7L18 draws too much power for any of the 4 slot scopes.
In spite of what the manual says, It is designed to operate in one
frame
There is also a tekscop...@yahoogroups.com which is a LOT more tolerant of

Someone has also started a Microwave equipment group too.

With Loran C shutting down in Jan, curious if anyone still uses it.
I have a z3801 but always liked the Austrons 2100s as another way to check
everything.
I pulled the old Gertch RLF-1 out of the basement and it still works.

Very sorry if I grabbed your thread. I thought I changed the header

The house and senate voted to shut it down and the president signed it.

The USCG and DHS said they had no need.
It was very hard

But that doesn't happend, right? *ironic tone*
With eLoran modernisation, there would be some chance of survival, but
obviously focus is on stripping down the suit if it
My impression is eLORAN is off the table. Since DHS is letting it go also.
Sextant, compass, and a good chronometer.

The tree reference is for nav in forest or jungle canopy areas. A very few

Unfortunatly very few commercial aircraft carry Loran C equipment. The large
ones would fall back on inertial navigation.
