10 MHz source dilemma

by VA3ELE Peter

Hi Ben et all, Here, Hugh VA3TO and I are using BLILEY OCXO, I don't have a part number to pass along as I'm not home infront of it. I believe 47NV..... It runs off 5vdc and is extremely accurate after just a couple minutes of warm up, stability is also top notch and the phase noise is excellent. We have been using these in our 10/24 & 47GHz systems for a few years now and no complaints. I found the 5v supply to be of great importance, as your portable battery system coukd easily drop below 12v or even into 11 or 10v, the OCXO still stays stable unlike some that require the higher voltages. After that most transverters will unlock below 9v and some around 8v. If I'm not mistaken, PACKRATS have a kit that they sell, a board with the built in 5v reg and the actual BLILEY OCXO as well at a reasonable price. Reaching out to the group should get you going. If you like to brew your own, the BLILEY OCXO are readily available on eBay too. Hope that helps. 73 de Peter VA3ELE

Looking for M2 2M9SSB yagi

by Fred Stefanik

Hello I'm looking for a M2 2M9SSB yagi to use as a "lab rat". I currently have 4 of these in my EME array and want to make some mods to clean up the pattern and reduce my RX QRN. If anyone has one or knows of one they want to part with (in almost any condition) please contact me. Thanks and 73, Fred, N1DPM FN32qb
