I already have the shx8800, and I'm worried that buying a K5 might just end up being useless because it will only receive weak signals. However, the K5's S-band and shortwave capabilities are very appealing, so I hesitated for a long time before deciding whether to buy one. Today, I discovered that the K5 can also receive and transmit CW signals, and since it was on sale, I decided to buy it immediately.
