My personal favorite is from Heathkit. In the early 80, while I was living in Germany, I built the Heathkit HR-1680/HX-1681 RX/TX pair. The HX-1681 transmitter is CW Only and runs about 100 Watts output on 80, 40, 20, 15, and 10 Meters. Coupled with the HR-1680 receiver, the pair runs full QSK. It was the only rig I had while I was in Germany and ran there as DA2EU. I mostly ran on 15 Meters and the combination worked great. The HR-1680 only has standard SSB filters followed by an audio filter, but it still works great on crowded bands. I still have it and still use it.
But my favorite may not be the best for you. You would probably be better off with a nice new all mode/all band transceiver. Almost all of them are in the 100 Watt range. But a lot depends on your price range. For example, I was looking recently with a $1,000 price limit. That $1,000 would have to include the transceiver, power supply, and any accessories. In that range there are some very nice radios, like the
ICOM IC-718 or the
Alinco DX-SR9T.
Either of the two rigs will provide you with all band coverage (160-6 Meters) and all mode operation. You may only want CW operation initially, but there are dozens of digital modes to explore and these rigs are ready to go.
