Rating:2016-02-20Birdies & Hash Anyone!?Time Owned: 0 to 3 months.After finding out all the Yaesu 1030 power supply at phoenix hro fans whine upon shutting down, Tried the GVZ4000 - It has some birdies and hash on 160/80/40m and less on other bands. Disconnected GVZ4000 - hooked up Astron liner birdies/hash GONE. Power adjust botton on right not lined up with hole, not centered.
Will mainly use on 17m where I have found no hash yet. Not really happy, I will work around it. Would not buy knowing what I know now.
Watch your switching supplies closely, operators have hash and do not test to find it is the GVZ4000! Rating:2014-08-08lot's of birdies, noisy fanTime Owned: 0 to 3 months.I bought this power supply as I needed a single supply that outputted 40 amps. I also needed front and back outputs as the operating position at my winter home is a little tight. I soon found out that the Diamond has a very noisy fan, and also some very big birdies, mostly on the 75m band around 3788,or right where I do most of my operating on 75m. Today I swapped it out for a Samlex 1235M. I still notice a few birdies on 75, but at a much much lower intensity.

I think I will leave the Samlex in for the time being, and try to resolve the birdie and fan noise issue. I see that people are swapping out the fan to resolve the noise issue, but don't see a real fix for the birdies posted anywhere.I did notice that if you adjust the power supply's output voltage you can move the birdies around,and also lower their intensity.
This little trick makes them ALMOST go away but not completely. I'm surprised that no one posted that on here. Rating:2014-07-25Inexpensive, noisy power supplyTime Owned: 0 to 3 months.Inexpensive power supply that should be able to handle multiple rigs running simultaneously. As others have stated, the fan is quite noisy and whiny.Pro:-Inexpensive-Light weight-Plenty of current for a 100W rig, or a small amplifierCon:-Noisy fan (loud and annoying whine)-Nut on power terminal doesn't come off (can't use ring terminal)-Voltage knob wobblesMod:-Replaced with a Silenx fan. Now the noise level is significantly better, although I can still hear it.PLEASE READ.PRODUCT REVIEWS TERMS & CONDITIONS-NOTES.
