In my case, now I have the Leo Bodnar reference locking fitted on my IC9700, I can properly test the doppler tracking of the ON0EME beacon, off the moon. The slight, but noticeable, uncertainties of 1

Ed, Hardly a recommendation....I use an HP 5753C and S parameter test set. The price was good! Calibration is done at the end of the test cable using professional SOT calibration and a good test cable

Actually, I humbly disagree with John. The easiest way to achieve a good match is to slightly press down in the centre of the driven element on the Wimo 67 element 13 cm......... make sure your VNA is

I would echo that. Excellent and great company. Several different whiskies tried as well! Airport on my way home. Sam, G4DDK

You are convincing me to put the 3cm (and 13cm) systems back on...... 73 de Sam, G4DDK Sent from Yahoo Mail for iPad

It probably wont. They were made for the receiver manufacturer and thn they either went bust or more likely changed the design. The 'generic' Lark 2.3GHz range filter specs seem to be close to what we

No John, These are miniature bandpass filters. NOT suitable for use between the antenna and the LNA. These ensure that anything out of band doesn't get beyond the LNA stage. Just like there should alr

Mike, I will send down 50 off tomorrow. That leaves me enough to take to GM next weekend. Sam

Looks like I will need to bring quite a few! CU there next weekend. Sam Sent from Yahoo Mail for iPad

Mike, I have quite a few left. I guess it would be best if I sent these down to you, for the component service to send out? For those who I have already said I would send to, I’ll deal with. Sam Sent

I still have a number of the Ceramic, 3pole, 2320MHz ceramic resonator.bandpass filters available for the cost of postage and a jiffy bag. I think Kent may also have given a bunch of these to the UKuG

There is much to be said for keeping the drive low. Unwanted 144MHz IF ‘leakage’ can often be heard over large distances (ask G4SWX) and with much microwave band activity IF being in the same frequenc

Although I previously posted on my web page that I was discontinuing production of the popular transverter kits, it is clear that there is still a continuing demand for both the Anglian and Iceni tran

Anglian transverter mini kits are still available....... Web page needs to be updated. 73 de Sam, G4DDK
