[VHFcontesting] 222 Tuesdays are BACK!

[David Pruett]

John,

When I e-mailed Paul, W1GHZ about boards for his 222 transverter a week 
or two ago, he said the Toko helical filters and the 5W power module 
were the "unobtanium" parts.  He said he was working on a substitute 
power module, but that it "wasn't a direct replacement".

His note said that he had "a few of the boards left" but the general 
tenor of his note seemed to indicate that the parts shortage was a 
serious problem.

It is interesting to note that all of the 50-432 DEMI transverters are 
not currently available because these are "in re-design".  I bet this is 
due to unobtanium parts...  In reply to a note to a friend of mine, DEMI 
indicated that they hoped to be back in production by late December,  
Also the 432 MHz Elecraft transverters were not available for a while 
due to parts shortages (but back in production now).
