Still a 6! Time Owned: more than 12 months.
I wrote the first review of this fine power supply. After 2+ years of almost daily use it still doesn't make any noise. On a scale of 1 to 5, it is still a 6!

Earlier 5-star review posted by WA0YSL on 2011-01-09

I normally use a big old Astron linear supply for my station, but I got interested in switchers so I bought this Jetstream. I've been trying to get it to make some noise, but I can't do it! No blower noise or RF noise at 100 watts CW. It's a nice looking package, and the switchable meter works great. On a scale of 1-5 with one being worse and 5 being best, I think I'd give it a six!

Outstanding! Time Owned: 0 to 3 months.
I've owned this for approximately 3 months and so far love it. Works quietly and without any problems so far. Reasonably priced and well constructed, in my opinion. Small in size so it is easy to fit anywhere and very light. Great power supply and we'll see how it holds up over time.

SUPERB Time Owned: 0 to 3 months.
I bought my PS last week in Houston Amateur Supply in Springs, TX , when I opened the box I surprised by the small size of this PS.
I must confess that I don't trust in switching PS due to his RFI noise, but this small jewel DOES NOT HAVE this RFI issue. I will buy another one for my shack.
Other feature I like is the iluminated dial and no fan noise

Great Switching PS Time Owned: 0 to 3 months.
I've been using Comm Series, Astron & Kenwood liner and switching power supplies but I decided to move to a singe 30 amp supply to save room on my desk. After doing some research and reading reviews I purchased the JPTS31MB from cheapham.com, a great retailer by the way. Received it 3 days later and I was up and running. I was surprised at how well this unit was constructed and packaged from the factory. The JTPS31MB has some weight to it for such a small unit, not too heavy but enough to give it a sturdy feel and not slide around on the desk. The knobs and switches are firm and tight. The voltage adjustment knob has a notch that catches at 13.8v keeping it firmly in place in the event that it gets bumped, which prevents accidental movement of + or - voltage. The meter is spot on and well lit with LEDs (not grain of wheat bulbs). The fan spins fast for a second at startup but other than that it's not noticeable. Even running my FT2900 at full power for long QSOs I can’t hear the fan while it’s running. I've used the JTPS31MB continuously over the past few weeks peaking at around 20 amps at times with it powering my HTX-100, Yeasu FT2900, scanner, and a few other DC accessories. So far it has exceeded my expectations and Jetstream seems like a great company with some affordable quality products. I've only used this supply for 28 - 440 MHz rx/tx so I can't comment on its use on HF transceivers other than 10 meter. If this power supply holds up over the years then I would say it’s the best deal you can find for a switching power supply of its rating. 73's

Very handy but not for 160m Time Owned: 0 to 3 months.
Small with good metering. The fan comes up on start then is inaudible unless there is a substantial load. I like the connectors in the back. Also the power cable is detachable, a nice feature.

The only problem is RFI. I bought it as RFI quiet to replace MFJ 4225, but the spurs on 160m are 10db stronger than with MFJ. Only audible with K9AY receive antenna. The spurs seem to be radiated by the mains cable.

Does A Great Job Time Owned: 0 to 3 months.
I decided to give this power supply a try as the price was right, and the good reviews here on eHam. I've been using it for a while now, and everything has been great. The A/V Meter has been spot on, no hash apparent on any of the HF bands, appears solid and well built. Considering I can buy two of these compared to the price I paid for my last power supply, with the addition of handling more Amperage I think Jetstream has earned a new place on my bench. All thumbs up on this PS.

Advanced Switching Power Supply Time Owned: 0 to 3 months.
The time has come...switching power supplies have finally reached refinement. The jetstream JTPS31MB
30 amp power supply is silent, small, looks great.
Built like a brick. Great lit meter for amps and volts. What more could you ask for? I use it for my VHF/UHF rig and various accessories. NO HASH on the HF rig that sits next to it.

A great, refined power supply at an amazing price from the seller on ebay or other web sites.

I have had this supply for 3 months. No RF noise on HF-450 mhz. Very small and well built. Street price is $ 89. There is a clone of this with powerpole connectors for $119 but the clone does not have the meters. I am not sure I like the knob on the front that varies the voltage. I like my adjustments on the Inside where they cannot accidently be increased to 16 Volts (damage to transceiver)

Excellent General Purpose PS Time Owned: 0 to 3 months.
I've never been a big fan of switching power supplies, especially when used with HF transceivers or receivers due to the hash and birdies produced in the HF spectrum. However, this supply is quiet, in terms of spectral birdies and fan noise. And, it's very small and weighs almost nothing compared to a linear supply capable of 25A.

However, times have changed, and properly designed "switchers" can be very quiet. And, this is one of them. Since the voltage is variable, I use it not only to power a Yaesu FT-857D, but also on my lab/test bench.

FWIW, this supply is not built in mainland China, but rather in Taiwan. I'm not sure that makes any significant difference, but the Taiwan-based PS manufacturers have decades of experience designing and manufacturing switching supplies for the computer industry.

When checking the Jetstream's voltmeter against a Fluke 77 DVM, the PS meter is dead on. I didn't check its accuracy as an ammeter, but I would expect it to be accurate as well.

I rate this a "5" and deservedly so. This little PS has changed my mind on switching supplies.

Great PS! Time Owned: 0 to 3 months.
This is the first power supply I've ever purchased. I was hesitant to buy a switching power supply because of all the comments I've read about the noise that they make. This thing is so quiet that you forget that it is there. The post are in the back so it looks very neat sitting next to my TS 590. The two way meter is a nice feature.
