ok for QRP  Time owned: 6 to 12 months
I have the 9040, the 40M version, I obtained mine used 10 months back. I have had a number of kits and figured that I would try a full 5W radio. When I obtained the radio I notice that it would not work off a 12V system, it stated in the manual that it requires 13.8V. I gave it 13.8 and checked the voltage regulation, it seemed to be off, so some adjustments were made. With a 50-ohm dummy load I show about 8 watts. With antenna connected it is showing about 4 Watts which for me is plenty to work with. I have also installed a K12 cw keyer inside the rig, it will fit OK and you can use some of the pins that MFJ has provided for their accessories. The version I have appears to be made later and I have only 1 or 2 reports of drift.  
Product is in production.
