|Customer Reviews for the MFJ-4230MV.|
|From: Steven K4ATZ|
|So far so good! I am using this in a GO BOX with a Yaesu FT 897 and a Yaesu hi power 2 meter rig and it works great. No noise, quiet and stable voltage. It has plenty of power for all my rigs and is nice and small! I would buy it again and would recommend it!|
|From: Joseph Fouquet N5JF|
|Great little unit it's built like a brick. The unit runs quiet and cool. Great to pack to take in the field.|
|From: Juan Martin LU5EOI|
|Almost the half size of my 706MKIIG.|
Solid, lightweight, quiet, no temperature at all...
and works Excelent on 220 volts.
|From: Jim KP2XX|
|It works. I've used this power supply on several radios that pull 15-20 amps under load with no problems. The voltage regulation holds on peaks without flinching. I'm amazed at its size. The meter and adjustable voltage settings is a real plus. A good power supply with great features at a modest price.|
|From: Robert Frawley w9uss|
|Very impressed. no noise and keeps up with my 100 watt SSB transceiver.|
My buddies were also impressed. Small but powerful. Yes I will buy more and use them in our commercial wireless biz.
|From: Matt Wilson K2MFW|
|Wow, this power supply delivers! Nice compact size, quiet and well made. I'm impressed.|
|From: Paul WD8DBY|
|This is a great power supply...its small size and large capacity output make a great combination for my deployment kit to power the commercial Icom F8101 ALE transceiver and a Kenwood TM-281. This unit easily handles the load and is quiet. The fan kicks on initially when the supply is first turned on but I have not heard it since. Highly recommend this power supply|
|From: Ron Masters N8NIX|
|As advertised and as noted in many reviews already, this small efficient power supply has no detectable noise that interferes with any of my operating frequencies. I operate a Ten Tec Omni 7 digital rig, and have never had to use noise reduction due to anything coming from this supply. I operate from a town home with an attic antenna that is very susceptible to switching supply noise due to proximity. I had to get rid of an LCD TV switching supply because of the susceptibility of my antenna/rig to such noise. I was reluctant to give this MFJ supply a try, but with the MFJ guarantee, I could have returned it if there were any problems. So I bought one direct from MFJ just to be sure. Well, there have been no problems. What a fantastic power supply. I have observed a rare birdie when I run a spectrum sweep, but if I tune to the frequency it's on, it seems to move away from the operating frequency within a few moments, leaving a pristine clear frequency. My noise floor is the same using this supply as it is using a stock analog Ten Tec supply. Note the Omni 7 is a general coverage rig, and I do listen to LW beacons on 340KHZ to 390KHZ, AM radio broadcast band stations, and SW stations ranging from WWV to CHU to all frequencies from 2MHZ to 30MHZ. For ham radio I check in to multiple nets across the 20M, 40M, 80M, 75M, and 160M bands every week, and am truly impressed with the performance of this supply. Yes, I said 160M, 80M, and 75M with an attic antenna, digital radio, and this switching supply. I'm going to buy a second one to replace the main supply on my Paragon backup rig. Thank you MFJ. One other item is that it is solidly constructed; looking, feeling and operating better than what I've experienced with other MFJ equipment in the past.|
|From: Nice Compact Quiet KD2EQU|
|This is a nice compact unit. Quiet and good looking. Performs well. One thing I do not like is that the positive and negative contacts are too close in the back. A high possibility of causing a short if traveling or moving the unit. The other unusual thing for MFJ, which prides itself on making most of their items in the US, is that this unit is made in Taiwan. Nice unit overall.|MFJ-557CODE OSCILLATOR WITH KEY$39.95
