Hi Joe, Leif and all Well not to much happens regarding our progress testing MAP65, in HB9Q we finish the feeder installation on our 15m dish but until now I can not put the WSE converters to work, main problem is to control the LO on the WSE, simple doesn't work. But our main problem was time, i just back from a complicate knee surgery and I'm recovery now at home. HB9Q is 100 km far way from my QTH means i need to wait some weeks and back to work on the WSE converters.
I did some test in my network and I find the configuration very simple but until know I have no chance to test over the Air, I try to use MAP65 on HF (14.076 Mhz) at home I have not EME antennas but MAP65 is fix on JT65B and on HF mode is JT65A, maybe some can Joe fix on the next versions to test the decoding Based on the extra time I have now at home I start to build a "poor man WSE converters", for sure the core will be linrad and the use of some softrock lite v6.2 receptors to produce 4 audio channels (having adaptative polarization is my goal). I'm close to finish the front end part, 2 receptors down from 144 Mhz to 14 Mhz using for both receptors a 130 Mhz LO (same amplitud and phase) and a +17dbm mixer, the second part are 2 softrock receptors with a diplexer in front plus a 14 Mhz IF amplifier, both softrock receptors share the same LO. I'm not desing nothing special, I decide to try that on the KISS way (keep it simple and stupid), I use some mmic amplifiers like GALI74, ERA5 and MAR6, 3 pole helical filters on the Front end part and a good desing for the LO (thank's leif for the ideas in your homepage) to have very low phase noise, the final part will be the DELTA44 and Linrad For Linrad I want to see if I have any advantage to run Linrad under linux, if some body give me good arguments maybe I try my first Linux setup, please dont tell me one is better than the other one, I'm not interested in how good or bad is one or the other OS, I only want to know advantge when i run LINRAD under LINUX otherwise I will keep the Windows version. For this "poor man WSE converter" I dont expect equal or better performance than the orginal WSE converters, dont worry Leif your WSE converters are the really State of the Art, I only want to build that for pure experimentation, i know the softrock receptors are simple but also are mediocre to bad in IP3 and intermodulation products, if everything go and run maybe I decide to produce something better on the back end part instead of the softrock, is better to have Adaptative polarization even with this mediocre system than nothing. I will share my progress on my homepage (as soon I finish the webpages) but please this project is not for somebody who cares until the las DB fraction, IP3 levels or high performance, is more related with a system can work with less money but off course with less quality, its a compromise, I want to see how bad can be the numbers. For this project the only instruments I have is a Spectrum analyzer up to 1.5GHZ ( no tracking generator), a 30 Mhz osciloscope and a Fluke RF probe. Maybe a serious evaluation need to be done by some body with more experience and instruments than me. Ideas and recomendations are welcome Best regard to all Alex Artieda HB9DRI ############################################################# This message is sent to you because you are subscribed to the mailing list <linrad@antennspecialisten.se>.
