First is 4M Hi Gain Amplifier (65W PEP for 10dBm input). It seems like it was designed for the Flex 6000 series. Made by FMBroadcast Parts in the Netherlands. See website for full details but it is plug n play with a 6000 series Flex. Unused apart from initial testing, £170 plus postage.
Secondly, a Kuhne TR144H+40 transverter for 144MHz, used with my 6500. This is the 'old' model (no LCD screen) but in excellent condition, £650 plus postage.
Scaling down and concentrating on HF + 6m, hence sale. Contact Paul M0CVX. firstname.lastname@example.org
