Hi Gang, I have an XV432 that is giving me fits. While my XV222 works FB with my K3/KXV3 combo, or any other IF rig for that matter, the XV432 has only worked well with my FT817 and 5W drive. While getting stuff together for the August UHF Contest, I now cannot even run the XV432 with the K3 because as soon as I select it, the radio locks up. The display is on but the buttons on the radio do nothing. The only remedy is to put the power cord from the radio and disconnect the I/O cable. Does not matter which of the 2 transverter ends on the cable I use. Again, the XV222 is FB and 432 won’t work.
Some Googling turned up NT4RT who gave a paper at the 2012 SVHFS conference on a bunch of mods for the XV432 to make it work better. Lots of ground via connections, connector rework stuff and loads of changing signal paths by scraping solder mask and cutting traces. All very involved. I have the paper in my Evernote account and will share if you have not seen it, pending NT4RT’s approval. I’m not sure it he wants it to be “public”. My unit has the errata items performed along with an input filter at the TX1 connection described by a DL ham IIRC. So, here are my questions. 1. Is anyone using their K3 with the XV432 in original as-built condition with good success? No self oscillation or other issues? 2. What mods did you make to tame the demons, if any? I’m to the point where I need to decide: A. Fix this one which may take A LONG TIME. But that gives me a K3/XV222 and 432 for 6/222/432 in the rear position of my rover with one headphone, one key, yada yada. B. Ditch the XV432 and use my FT100D as my 6/222/432. This is a pain because running on 6 and 432 key 222. I’ve run into problems doing this and it really requires that the XV222 be turned OFF except when in use. I suppose I could build a switch that would power up the XV222 when I’ve selected the 28MHz band on the 100D. C: Build another XV432 and use the current one for spare parts. Your ideas are greatly welcome. -- 73, Mark K2QO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
