Spoke with Tom 002 West Birmingham UK today on 27.205 AM on the flat side. Can't ever recall working a UK station on the AM side....usually SSB...until today.
Dang it, 144. I usually have the beam pointed north. I forgot you was south of me. I did hear you the other day on ch20 am. I'm up around Oxford / Anniston area...south side of Coldwater Mountain. I'm always on ch20 AM in the shop....it makes it easier for customers to get in touch with me...
Spoke with Maryland, New York, Oklahoma, and Florida this morning. Then I spoke with Chicago all afternoon on Ch 20 AM. Skip was rolling all day long from 6am to 7pm in Alabama.
That 100 watts you were running was really doing the trip, 808. I tried to go on the flat side to get you but couldn't hear anything and had to go back to my vertical. Sounded top shelf on that Cobra 148GTL
CH 20 AM. worked 133 in Bakersfield. Then Sportspage and skid row. Talked with the west side most of the afternoon. Then spoke with #1 Equalizer in Trinidad. Trainman just choo-chooing along.............
Well guy's this was a tough one. I did manage to find the problem. If you look between your 455KHz filter and the big 7.8MHz Filter there is a resistor and a diode.(D3, I believe) The factory sure used a lot of that glue on one side of that little black 455KHz filter. I removed the glue and...
I have a 148GTL that receives low on AM only. SSB reads fine. When I inject a S-9 signal into the antenna jack the radio's s-meter reads 9 s-units on SSB. When it is injected on the AM side it reads about 1.5 s-units. All the cans in the rx chain seem to peak ok and none of the slugs are...
It's all good, Handy Andy. My unit is the 29 LX LE non Bluetooth. It has been discontinued for awhile. Not sure of the board number as it's all buttoned up now. Looking at your schematic.....If you follow where the RSW (weather audio) connection is from the front smd board to the main PC you...
Hit the nail right on the head, Nomad. The primary of L9 had a discontinuity. Replaced L9 and I have receive. Re-tuned the rx chain and I can hear a mouse fart in Mexico.Thank you for your help.
Handy Andy.....Thank you for the info. I'm going to add that in my notebook for future reference...
Nomad......TR8,9 and 10 are ok.
TR8
E=.778v
C=7.11v
B=1.5v
TR9
E=(ground 1.44mV)
C=1.65v
B=.758v
TR10
E=.801V
C=.818v
B=1.6v
TR23 Regulator is good supplying voltage rail for RX supply.
D4 detector is tested good as well.
Volume control pot is good. I'm going to check out TR10 again. Just looked...
I have a Cobra 29 LX LE that transmits fine. It has great modulation. PA works just fine. I have NO signal on the digital S meter and no audio coming thru the internal or external speaker. Not a mic issue. I can hook a signal generator to the antenna jack and hear no audio or signal. I have...
