OK here it is. I can tune 40SSB portion with no problem but when it comes to 40 cw it is a no go. Before I venture out and take down my 40ft vertical should I...
The first thing I'd try is adding another radial or two. In a somewhat-similar situation last winter (temporary substitute for a faulty BigIR) I had trouble...

I wonder if anyone has made their own SmartLock, using the circuit in the SG-237 manual? If so, I¹d like to discuss (on or off list) components etc, since...
I don't have a 237 diagram to hand - nor indeed at my side a 'standard' smartlock. But if it helps, I built mine (for a 230) and found it very flexible...

Hi, I just build a loop antenna. It is a square with about 5ft spscing between the corners. I have 5 windings for a total of around 100ft of #12 thhn stranded...
Hi Andy - While I never used anything like this, I don't think that 5 windings in such a small area are going to do you much good on the air, even though the...
Thanks for replies Red LED is LOCK LED and always ON in my circuit, although SGC manual says it should flash, but I thought the Zener/Cap/Transistor would...
Re: Maths Anxiety. Your trains are approaching each other at 140 mph - that is the rate at which their separation is decreasing. The 60 & 80 refer to their...
I discussed this at my local club last night and they all confirmed that Tantalums are voltage polarised, but not electrolytic. I didn't realise this. So my...

Dudes This is probably no help without looking inside but I just checked and the locked led flashes on my unit. Its a smartlock pro on a 230PRO if thats any...
Hi, I have the Smartuner connected to a long wire. I would like to ground the antenna when not in use. What is everyone using for a switch. It would be...
... I am using a heavy duty DPDT porcelain knife switch. One SPDT is used to switch the long wire to the coupler---the other way grounds the longwire. The...

Hi Kav and all here, you understood what i want to do. Now i'm sure that's possible to dismantle the mount to change the feed wire without problem. As it's...
No problem Didier I'm sure it was this group that pointed me in the right direction initially. The hardest part will be finding suitable wire. Strip some of...
