Hey ivan:
well, I'm afraid i will not be specific enough but I do have some ideas. CCrane has some good models, there is a lot of discussion of their models, and similar ones on the CCrane yahoo discussion group. Many of the Kaito units appear to be very good.
Check the Grove enterprises website, as well as Universal Radio's catalog.
I use an Icom R75 which, with a decent length of wire, works very well. It has the added benefit of being one of the best (for the money) shortwave receivers around.
Possibly the best, or most cost effective, solution would be just adding a select-a-tenna to your existing radio. These things work great, they have been around for a long time, some don't even need power. Check either Grove or Universal for these. Either one would be helpful for you if you can call them on the phone they probably have experienced customers in your position.
GOOD LUCK
STAY WARM!
