As I have stated previously I purchased a 1296MHz transverter from SG-Lab in Bulgaria. Anyway, upon applying power to it and testing the transmit (with an IF of 145MHz at 2.5W from my FT-817) I noted that it was not working as described. Upon opening up the top of the case I noted that one of the components was raised and obviously burnt. I contacted Hristiyan, LZ5HP, at SG-Lab and sent photos of the faulty component in situ. He immediately identified it as a short in the choke having caused the problem and I returned the unit to him. Two weeks later it was back with me in full working order with a replaced choke. This time when I applied power and some IF it worked as it should.
I also mentioned that I would look at constructing a DL6WU Yagi but, unfortunately, work has got in the way and I just haven’t had the time. I looked online for suppliers and, after much deliberation, decided to purchase one from Dual Antennas in Serbia (www.antennas-amplifiers.com). This was down to both price and quality. Although there are manufacturers both in England and in Germany, Dual seemed to offer the best deal. For a 13 element Yagi it cost me 59€ plus shipping. there was the other issue that when it arrived in the UK it was held by customs for a week whilst they added import charges and VAT but that only came to £19.15.

So now I am fully operational on all bands from 80m – 23cm (except 4m currently). I have not yet had a QSO on 23cm although I have put out a few CQ calls, so maybe next Thursday evening during the UKAC contest.
