Hi Peeps... Ok Tanuki, but it changed NOTHING... I even added one turn to the coil and effectively no effect.. However..............I removed the Local osc valve V3 and did what I should have done on day one...... fed a signal from the tracking generator, to the ant input and monitored the output on the spectrum analizer at the grid of the mixer. On all bands except 15... perfect expected results. On 15.... no tuning at all, thus after all this I conclude the Beehive to be S/C or VERY Leaky. This would obviously damp the tuning, and give very weird results, also the sensitivity on that band was 40 db down... Thus.. I have ordered 2 x beehive trimmers from ebay, and expect delivery on weds., I am not even looking for any more suspects. I have things to do tomorrow (Mon) anyway. Watch this space..
