Thank you. I don't have know what board area I have available, but I
think think its going to be considerably less than that size. I think
the only option will be to use an TCXO, which to be honest is good
enough, but if there were small rubidiums, I would consider using one.
But it seems they are not as small as I would have liked.
What board size do you have,
I don't actually know, as I don't have the transceiver yet. But given the board
sold had basically a TCXO and not much else on it, its not going to be large
enough for a rubidium.
what stability do you really need?
To be honest, a bog-standard crystal is probably just about good enough. There's
not much point in going much more accurate. But an TCXO was offered as an
option. Getting that would be a "nice" improvement, but they are hard to get. I
suspect they would fetch as much as a rubidium due to their rarity.
But if I'm going to design my own board and put on an osciallator, I might as
well put a small ovened oscillator. Most of the hassle will be designing the
circuit - the cost of the device is not going to be a major hassle.
Give theres a wide range of volatages in the rig (including 28 V for the final
PA transistors), fitting a small over should not present any big problems.
Can you fit a DIP14 package?
Cheers,
Magnus
