Terry developed a torn retina in January, and a blood vessel burst in that eye while we were at Hamcation in Florida in February. He’s been going to our eye doctor every week since we got back from Florida to see if the blood would drain from his eye on its own. Over the weekend he started having flashes in the eye and it went darker.
He ended up having emergency surgery and they found a very nasty detached retina.
He has strict restrictions for a month, but we’re going to try to get as many orders caught up as possible.
We apologize, profusely, for the delay in getting orders done.
For anyone interested in the new ICOM IC-905 – I gave presentations at Central States and at the N.E.W.S. conference on my one-year opinion of the rig. You can view it in our “TECH Notes” section.
After hearing about the demise of 3456 MHz here in the US, I contacted Dave Olean, K1WHS, who is the previous owner of Directive Systems and had originally worked on the 9cm loopers. He confirmed what we saw, there is a VERY slight degradation in gain moving them down in frequency. Here are the results:
DSE945LY – .5 dB
DSE976LY – .4
DSE9112LY – .2 dB
As my friend Gene, W3ZZ, used to say “the DX will never know the difference!” The percentage of frequency change is so slight that the return loss still should be in the -20dB range which is 1.2:1 or less.
Going forward we will make changes to the loop lengths on any new 9cm loop yagis. We anticipate opening sales again on 9cm loop yagis sometime in late March or early April.

Does your Power Divider Look Like This?
Some manufacturers charge twice as much, but only guarantee 20dB of Return Loss. Directive Systems guarantees at least 30dB (1.065:1 VSWR) of Return Loss in the most popular portions of the amateur bands.
