Nice little rig!

I just picked one up off of E-Bay for $76 plus shipping. Same comments as other reviews - tuning is smooth; RIT and variable filter are also nice features. First contact was Costa Rica with a 569 report. Not bad for 2 watts into a dipole in the attic. Seems to be a much nicer radio than the MFJ9040 and TenTec 1330 that I previously owned.

Excellent basic monoband CW Rig
|
Time owned: more than 12 months
|
I have had my 40M Explorer II for a few years (I am the original owner and builder). This is one of my all-time favorite OHR Rigs.
It is a bit more chunky than some of the current mono-band QRP CW rigs but it is a real pleasure to use on the air. I am always amazed at how quiet, yet sensitive the receiver is.
Signals just seem to pop out of nowhere with almost no background noise. The variable bandwidth filter works very well
and the rig sounds as good or better than many commercial rigs costing many times more.
I am currently using my rig with the power turned down to 950 mW for dedicated milliwatting. BTW the Explorer II has a much improved Rx as compared to the Original Explorer. I also have an OHR 100A and it is very similar in performance to the Explorer II, but for reasons I can't quite put my finger on, I prefer operating the Explorer II.

Its been a few years since this kit was for sale, but used ones are a bargain. This radio has a real VFO with a reduction drive and a variable filter. Like all OHR rigs, the reception is clean and easy on the ears. The keying is nice and the receiver sensitivity is more than adequate. While not a mini-rig among QRP monobanders, it is has a great feel to it and operating it is a real pleasure. I bought a 20M version and liked it so much that when I found a 40M version at a hamfest, I bought it immediately. All around great little rig. OHR rigs tend to be short on bells and whistles, but long on "classic" feel and just plain enjoyable to use.

Solid Radio
|
Time owned: unknown months

I bought the 40 meter kit from OHR about 4 years ago. My father, who is a retired EE, built it for me because his soldering skills are much better (even at 80 years old). The rig worked first time we fired it up. I've been impressed with the receive audio. It has no built in speaker, but the LM380N chip will drive a 4 ohm speaker with reasonable volume. About a year ago, I accidently reversed the polarity and fried a few components. I know...it was a stupid thing to do, but my middle-age eyes betrayed me on the power cord polarity. Anyway, it took out a diode or two, the LM380N-8 audio chip, and another chip. All the components were easy to find except the audio chip. It's not the 14 pin variety of the LM380...that would have been too simple. After calling around, I found one at a supplier up in the upper midwest. We got it running again no problem. This time, I built a fuse into the box...something I should have done the first time. My favorite part of the radio is the variable filter...really nice for eliminating QRM. It puts out a solid 3 watts.
