Hello Andy, Any chance did you met to say L28 instead of L22 ? L22 on the schematics that I am looking at is tied into the channel selector and the main Ic chip pin 2. I didn't follow any more of what else it is tied into. Its a tunable transformer with the ferrite slug. Without having the...

Hello Bruce, This is really nice of you to offer. I will keep you in mind that's for sure! Thank you much.

Hello Andy, Yes I was trying to create the EKL as you had posted earlier in this discussion. I used a 470 and a 3.3k along with the 1n4148 diode. I used these values as I had seen in one of the Pics. If I may ask, what resistors would you recommend for the EKL creation? And in what...

Hello, Okay I have installed a new Mosfet once again on this rig. The Red like tube looking thing is in the Pic is just Red Heat Shrink protecting the leads from shorting out. Anyway as soon as I had turned the rig on, "D8" had started to smoke again. Now prior to the Mosfet install, I could...

Okay right after posting above I decide to install a new Diode in D8. Also I think I failed to mention I had replace C123 in the beginning. Well believe it or not, D8 did not melt! It seems to be holding its own. So it may be due not to have that sleeve on the bolt of the Mosfet when it was...

Okay thanks Andy. Well I would like to mention when I received it, I had about 1.5 watts to the watt meter before starting this original posting. As mentioned it had the RFX75 installed. After opening the rig up, I had discovered there was a fuse holder inside the rig and this fuse holder...

Andy, you have the Patience of Job, seriously. I feel really bad because I should had Not said " 0 " ohms. I should had said there is NO Continuity from the ground of the Mod tranny to the Cathode side with diode removed at D8. Meaning it is an open circuit.

Hello and thank you Andy for the links. The sticker on the back shows Feb 07, so I guess 2007. Only history I can mention is it had an echo board installed that I had taken out. Also it has a piggy back potentiometer for the swr cal and a talk back volume control that is still installed...

Actually I am getting a continuity reading from the Anode side of D8. I stepped the ohm meter up to Kilomhs and it read .833. So I stand corrected, sorry.

Okay, I had removed D8 due to letting the smoke out when powering up the rig. I have also removed the Mosfet all together. I have no continuity on the Cathode (-) to transformer ground. When checking the Anode (+) to transformer ground I get a quick signal of continuity but as quickly as I see...

Hello Andy, thanks for jumping in here again. Okay I have continuity on the Cathode ( - ) side and no Continuity on the Anode side ( + ) Its been a while but if I am thinking correctly this insures me there's no short in the transformer of T1 ? Is this correct?

Scratching my head here! I didn't mention this before, I thought it was a easy fix. The fuse was blown in the RFX75 and when replacing the fuse and powered on D8 popped and of course the fuse blew as well. Obviously I should had used a smaller value fuse! Anyway I replaced D8 and did the...

That would be a great idea! Perhaps for other transceivers as well. Andy, You are making this to easy for me, thank you! I will have to look in my parts bins or I may have at least one junker of a radio that I had saved, maybe I'll find something there. Using an inductor calculator with a...

Thank you for your thoughts on the RFX75, but No it Does Not work at all. Besides the man who owns this does not have a large enough supply to accommodate the current that the RFX75 draws to be used inside of his home. Again thank you for your consideration.. Andy, thank you for your valuable...

Hello Handy Andy, Its nice to see a pic of that coil/inductor, thanks! It looks like some wheres around 6 maybe 6.5 turns. Maybe turn some enamel wire around a very small tuning screw driver might get it close enough to work to experiment! Any chance could you tell me if the part numbers are...
