It would be good if you mention the W1GHZ style of fairly inexpensive transverters that you can make using 28mm pipe end stops as the filter elements. These usually produce about 15 dBm output and can drive something from Ebay to get a bit more power cheers Geoff GI0GDP

Morning all, I'm writing a brief 13cm beginner article for Radcom (hopefully if accepted!) similar to the one I had published on 23cm in January, with a view to hopefully encouraging a few more on the band. I've covered the mobile phone mast interference many of us have experienced and am looking for a spec analyser picture of the large signals that can occur near (or in) the band to include in the article (think GM4DIJ put one up on FB if memory serves but can't find it now!). Will need to be non-copyright but the photo will be credited to the supplier. man thanks Andy G0FVI |

Here’s a couple. I put a 20dB gain block in to accentuate the plot. 1.7 to 2.7GHz Morning all, --

Morning all, accepted!) similar to the one I had published on 23cm in January, withIs this it ? Feel free. I used a single cavity filter to get rid of it. There is a discussion in the group archives . Around March 26th . "Cellphone interference on 13cm - stub notch filter" I tried stub notches but they were no good. Cheers Brian GM4DIJ -- Brian Howie |
