[DSP-10] Choices of Oven VCXOs?

[Doug Bade]

         I to am using the HP Z3801A. I know it is a little more than Steve 
was asking about, but the performance of mine is exceptional. I built a 
choke ring antenna, which is sitting IN the garage, looking through the 
ceiling, and GPS as well as 10 MHz, are locked and steady ( I know this is 
no measure, but just too much snow falling outside right now and I have no 
radome on it...) I have 2 of them, and when checking them against anything 
else in the shop, they are well in manufacturers spec.. It seems to me too 
for $399.00, you get a lot of equipment for a very fair price....Even when 
GPS lock is lost and they are in hold, the freq stability equals and 
exceeds my service monitor which is an ovenized 5 yr old HP.

         Completely off the subject but interestingly;

         In a busy service shop, the waterfall display is really amusing to 
watch looking at 144.1 in SSB mode on an outside antenna. It is amazing the 
correlated energy it sees listening to the noise floor... I saw what looked 
like a doppler shifted signal move in and back out of the pass band about 
1.5 khz freq shift over 5-10 mins.. No Idea what that was... fairly wide 
modulated energy, so not like a local osc... about 800 hz wide...

         Enough noise... 73, Doug KB8GVQ
