Elecraft K3 Review
| NE3R | Apr 4th 2009, 19:00 | Build quality | |
| Purchased: USD 1.00 (New) in 2008 | Features | ||
| Time owned: 6 - 12 months | User friendliness | ||
| Value for money | |||
I've had the Elecraft K3 for about 9 months and I've found it to be an excellent radio. I ordered mine in unassembled form and greatly enjoyed putting it together. I ordered the 100 watt version, with one optional filter, 400 hz 8 pole for CW / Digital modes.
It is not the most ergonomic radio on the market, but it is still easy to use. ![]()
