well guys the storm got the the best of the net tonight. I copied Bill KV6Z and Chas NK8O The noise here was S9 PLUS The thunderboomers are just west of here now. tnx to those that I may may have

I wonder if the receiver is cycling through an oscillation at audio frequency. Like trying to super-regenerate, but at an audible rate? Duane KE0IUV Sent from TypeApp

Ray, What is the type of transistor tester that you are using? I have an old M3 Tester but it does not indicate capacitance. That is really cool! I had a 77WS IRF-510 and when I replaced with

I agree :) The Bayou Jumper is a great rig !

Update Hooked up to an antenna and heard a signal. It was weak but it was there. Buried in the buzz.

I have done some more testing and with my crummy little scope. I have only run the radio on a 9 volt battery. I did some poking around. Touching the antenna center pin produces loud scratching in the

Cant make it after all...finally got maint to let me on the 8th floor roof...lots of corrosion on antenna fittings. took antennas down. and replacing them If you don't change direction you WILL

Just finished the BJ I bought at the end of 2017. No, I'm not that slow, but could start on it until now. I've built several of the 4SQRP kits over the years and I have to say this is one of the

The two output pins of the NJM2113 audio amp chip (U1) are each biased at about 6 volts DC. That's why they can't be allowed to be grounded - it shorts out the bias voltage and zaps the output

You are definitely not alone on no crystal osc. I found after many hours of work, that the bias of the oscillator of is very important. It needs to be at least 3.00 volts. Check my report in the

Darn. no 'c'. Well still like the way you guys think! The manual said at least 1 uf. would 10 be better? Also it says if using electrolytic with polarity, Positive side to the tip and or ring of

JP2 and JP3 are only on the rev A(c) boards. You can find that "revA(c)" designation on the silk screened legend just above the L5 and L6 on the top side of the main board. The earlier green panel

Where are JP 2 and 3? I only see JP1 on the manual. I know mine is a rev A but I am not sure if it is an A(c). Bob

I am sure some of us like me just assumed we blew it and replaced it on our own. They are not expensive and in my case I could get them much faster locally. Cheers Jeff Vk3GMO
