Whilst there we had a KW2000. At the time we thought it was wonderful. I can recall working some impressive DX with it. I cannot remember the antenna we had, but I don't think we had a beam. In the following years, we had a later version of the KW2000 and a KW linear. I think the original version was 90W pep. There was an article in Short Wave Magazine on the KW2000B.
I took my morse test in the Liver Building and used an El-Bug on CW with the KW2000. I also recall working ZB2VHF on 4m AM from the club on 70.26MHz with 4W.
