Maybe this will help.

Thanks Chris! I looked at that one too and it doesn't look like it has the oval hole in the heatsink, the IR logo is different, and the small circular indention in the Mosfet body is on the bottom, not the top. For all I know, the MS1307's that were in the 703 were "rebranded". I am just...

Mic type should be Electret. As for Mic gain, I would set it while driving the Expedition and key the mic without talking. Set the mic gain so no RF is coming out from background/road noise. A nice plug & play upgrade is the President Digi Mic. The channel buttons don't work - and never will...

Unfortunately, the RFParts MS1307's were different too. No oval hole in the heatsink.

I got tired of all of the jammers on the 5's. I hang out on 27.370 LSB. No jammers and a lot of friendly operators. Main call in freq. for the WWS group (World Wide Sidebanders), also Needle Benders and World Radios too, so please be courteous and don't have a long QSO (5min+) there (please QSY...

LOL, you haven't mentioned what kind of mic it is. Kinda need to know that before advice can be given... Stock, Aftermarket, Dynamic, Electret, Noise cancelling, etc.

You guys do realize that the MACO V2, V3 & V4 are just Delta Loops that use a gamma to match. You can change polarity by the orientation of the antenna.

I understand the rules and wish to enter the contest.

Here is what it looks like.

Rebuilding a KL-703 that has IR branded MS1307's. One of the PushPull circuits got wiped out due to a solder ball that shorted a Drain & Gate. I have RM3's but they don't match. I can't source any that look the same. The Chinese stuff is all rebranded. I will try to get a picture of the...

1, 3, and 7... Awesome! Pez - now just get them to use the Q6pro guts in a short case with Q5 Display & Heatsink.

Just had a nice QSO with NeedleBender 24 Francis 20 miles north of Belfast Ireland on 27.375LSB. He's there now. Getting some NE corner coming in.

LOL. I have the worst luck. I heard JJ sign off with 08 Tropicana in Honolulu and I tried to make it back to JJ but he was gone (conditions may have fell out). I guess third time isn't a charm...

Just missed JJ again on 375LSB, dang it. He was signing off again when Mark in S. Georgia and I were trying to get back to him. Maybe he will be on later or tomorrow. Lots of rag chewing in Florida, Georgia, Carolinas, Kentucky, and West Virginia. Even some Australia.
