However, if you only have 3 radials covering 90 degrees then you'll get some Thu, 19 Nov 2009 16:28:17 GMT Mark Spencer http://groups.yahoo.com/group/Smartuners/message/3404 http://groups.yahoo.com/group/Smartuners/message/3404 I have had good results with a setup similar to yours except I was able to lay down dozens of variable legth radials.  I would suggest putting down as many Thu, 19 Nov 2009 13:01:32 GMT ea3adv_qrp http://groups.yahoo.com/group/Smartuners/message/3403 http://groups.yahoo.com/group/Smartuners/message/3403 Hello to all the group I have just joined the group because one of my new projects is to try to upgrade the modest antenna setup I have on the roof of the Mon, 16 Nov 2009 14:55:44 GMT K6SBA http://groups.yahoo.com/group/Smartuners/message/3402 http://groups.yahoo.com/group/Smartuners/message/3402 Hello all, I recently had a great experience getting my SG-237 repaired. I had purchased it used and it was DOA. I found out about Steve Senft at Jaytron Mon, 16 Nov 2009 13:53:08 GMT mschreiner@... http://groups.yahoo.com/group/Smartuners/message/3401 http://groups.yahoo.com/group/Smartuners/message/3401 Phil, I did similar with my tuner. I'm away from home now, though, so don't have access to make sure. You should be able to use an ohm-meter to measure for Mon, 16 Nov 2009 13:38:53 GMT Phil Snyder http://groups.yahoo.com/group/Smartuners/message/3400 http://groups.yahoo.com/group/Smartuners/message/3400 I have an SGC 237 here and have just installed an Inverted "L" off my 55 foot tower with the tuner feeding it at the base. I have the tuner mounted in a Mon, 16 Nov 2009 11:42:41 GMT Mick http://groups.yahoo.com/group/Smartuners/message/3399 http://groups.yahoo.com/group/Smartuners/message/3399 Hi, I have a 230 that continuously tunes. The LEDs do the 'right' things WRT FWD PWR and 2:1 etc. Question however - occasionally the FWD PWR LED flickers - is Mon, 09 Nov 2009 16:45:36 GMT ve1ps_1 http://groups.yahoo.com/group/Smartuners/message/3398 http://groups.yahoo.com/group/Smartuners/message/3398 Is anyone using a TS480SAT and SCG tuner as a combination? If so, I have a few Elmer type questions. Please let me know as I would like to take some Fri, 06 Nov 2009 22:40:56 GMT Callum MØMCX http://groups.yahoo.com/group/Smartuners/message/3397 http://groups.yahoo.com/group/Smartuners/message/3397 Jim, if you have an SG230, your problems just went away. The only thing you need to be creative about is where to sling the wire. This is precisely why I wrote Sun, 01 Nov 2009 22:53:57 GMT yah121d http://groups.yahoo.com/group/Smartuners/message/3396 http://groups.yahoo.com/group/Smartuners/message/3396 Thanks all. Seems the tuner is okay - no damage done. I've brought it down and played on the bench, it tunes where it can, it remembers, TND line functional; Thu, 29 Oct 2009 20:23:28 GMT Randy Farmer http://groups.yahoo.com/group/Smartuners/message/3395 http://groups.yahoo.com/group/Smartuners/message/3395 ... Looking at the schematic, it appears that there is no direct DC return path from the "ground" side of the tuner (represented by the chassis ground terminal Thu, 29 Oct 2009 19:26:18 GMT yah121d http://groups.yahoo.com/group/Smartuners/message/3394 http://groups.yahoo.com/group/Smartuners/message/3394 ... Thanks - and for the link, my compressed version's diagrams are about unreadable but now I can see. If T1 (a) is now o/c, it might have taken T3 & T2 Thu, 29 Oct 2009 16:26:58 GMT Randy Farmer http://groups.yahoo.com/group/Smartuners/message/3393 http://groups.yahoo.com/group/Smartuners/message/3393 ... If you applied a fairly "stiff" power supply to RF input, you've probably taken out winding A of transformer T1 in the RF sensing circuitry.

Looking at page 1 of 6 of the SG-230 schematic (SG-230 manual downloadable from SGC website) it looks like a winding of transformer T1 connects from the RF Thu, 29 Oct 2009 15:10:18 GMT yah121d http://groups.yahoo.com/group/Smartuners/message/3391 http://groups.yahoo.com/group/Smartuners/message/3391 Not sure if this was posted - please ignore if a dupe. Any thoughts on what I've done here. Whilst testing my 12v via coax interfaces, I've managed to apply
