[time-nuts] Recommendations for time beginner?

[Frank O'Donnell]

Hi, I'm extremely new to the topics covered on this list, but am finding 
reading the message traffic to be highly educational. I have some 
questions that I'd like to put out, and apologize in advance for them 
being at a greatly simpler level than most of the discussion here.

I came to time-nuts by way of an interest in frequency measurement as a 
radio ham. To supply a 10 MHz signal to my gear I bought a used Trimble 
Thunderbolt. I always like to have a backup, so am thinking of obtaining 
another device (either a GPSDO or something else that can provide a 10 
MHz signal). For a beginner, is there something else that offers 
accuracy/precision at least as good as a Thunderbolt and doesn't cost 
more than a few hundred dollars at most that you might recommend?

I also have some questions about using the Trimble, but will put those 
in a separate message.

Thanks,

Frank O'Donnell
