With lower voltage, the load will pull more current. At $16 to $18 per psu, it's worth experimenting with them. The site that I read said 13.3 to 13.5 volts capable without tripping to over voltage protection. Worth a shot. If it works, I'll share it. If it fails I'll update.
The link says a jumper but back when I did this I read a resistor on another site. I can confirm that the resistor works but I will try a jumper on the new one.
This is the exact same power supply (dps-750rb a) I got from tba years ago. It worked great at 12v. I dug it out of the tote with radio accessories to check. I used a 390 ohm 1/2 watt resistor to get it powered up. I found another post about raising voltage which I want to try. I will update...
After reading more it would seem that I can't get all the characteristics of the crystals in order to match without more expensive equipment. :( This kind of ruins my idea of relying on simple equipment and calculators to make my own. It would seem that the easiest (and cheapest) route in my...
Thanks. I've been reading up on chebyshev design and I found a few calculators. If research was all I had to worry about, it wouldn't be as bad. I also have to worry about finding quality parts. As I've never sourced crystals I'm not sure where to order from.
I saw a post by Robb for bandpass filters and started reading /watching YouTube videos to study up. My direction is a little different than Robb's and rather than hijacking his post I figured I'd start my own.
I'm looking for suggestions for quality crystal vendors where I can order 50 or so at...
What you are wanting to do is mostly frowned upon by those trying to enjoy the hobby. Personally, I don't care because TX is so far from me and you won't be adding to the noise in my receiver. You may want to watch how much you bleed over the band too. With enough interference, you're bound to...
From what I read, this was repeated on the bench but the external swr meter showed a different reading until he raised the DK to 3.7 watts and then it matched.
I'm not familiar with the 980 and I'm not sure why simply lowering your dead key would change the swr reading in the radio unless it...
As with everything, it's all opinion and price. For me, if possible, I want to keep things stock. I would like to improve the bias in the ts250 but my knowledge prevents me from doing it myself (for now). There are no real techs I'm aware of (nearby) that can do the work.
90% of the reading I...
I used to drive up there twice a week when I was driving a truck for a local tile distributor. I dreaded those days as I had no chance of missing rush hour traffic and I was heavy coming home. I know your pain but glad i didnt have to deal with it every day.
