In this amp there are 2 resistors R2 and R3 (maybe a voltage divider for the Hi Lo Sw3 whick looks like Hi Lo input adjust?) the schematic shows the values of 68 Ohms each but in the amp it has R2 15 Ohms and R3 47 Ohms. Was this done to change the input range? What would two 50 ohms do there...

I do not have any resistors under the board but one for the clarifier mod and one on IC20 a TDA6130 double balanced modulator IC BTW first digit on mine is a 4

Here is look at the output on my SA settings shown on photos and does it ever look ugly i think it can spur wifi freqs lol. This is in Am mic gain off and power set to 5 watts the 100 watt rf amp is not connected in the radio. . Here is a shot at 1 MHz span it spurs at every 100KHz on 11...

I will toss it on the SA and see what the spacing is on tx and thanks for looking also I noticed A choke missing on the radio L33 that is on the schematic not sure if it matters but it is in the circuit that you adjust VC3 for the lowest harmonic at 54MHZ so says the alignment page using a...

I will use this old thread.. I have a eagle 5000 that txs and rxs way to wide you pick up clean 3 channels in either direction and tx the same plus tx tosses spurs all over the place with or with out the shorting bar in on my spectrum analyzer and not really spurring on the harmonics no real...

Audio is a little tiny sounding no lows to speak of maybe another cap in the comp board or audio section.

C727 a stage coupling cap was bad, I used a home made RF/AF sniffer to track it down

Flexing the board does not seem to do any thing but if i inject a tone at the output of the comp board i get some ssb output on the watt meter so i am thinking a ground cap has went low maybe or an transistor amp is leaking perhaps

It has good am and ssb rx and good am tx but very low ssb tx less than half a watt but can be heard on a nearby radio very weak.

Safe to say your pa section is good it does full output on some bands the problem would likely be in the filter section dirty relay, bad cap or diode not much else in that section. Or some issue that the radio can not tune down the SWR on that band. Grab the schematic of the filter section and...

Hey nomad if you could PM please. thanks

OK got the bias adjust in I get 0.65v right before relay kicks in I have 35 volt at the 1407's and keyed i have 32 volts and 13.6 at the supply binding posts. I get about 330 watts out of it on ssb All seems to be working now. Thanks to Tallman and Bob for the help . Now if i can get that...

Been a while i am back at it again it is working right now swapped the boards out with the newer version I wil post some results soon...

Gave up after a month and sent it on it's way. worst radio i ever worked on, the way it was designed with so many voltages of 42 at the source and 29.1/23/12/8/5 when the supply takes a cr#p it sends 40 volts every where.

Got a TS-940 that the 28 volt line to the PA board shorted and took out the power supply after changing a lot of parts in the avr board and the heat sink transistors it fired back up rxc was great but on tx the radio chatters over speaker like motor boating along with a a relay on the filter...

I have one and they have a glitch when using an external speaker talk back comes out of it on TX when TB is turned off I posted a fix for this in the forums. Other than that I like the radio only wish it had up and down CH on mic or front panel buttons.

also clean the power switch it has separate contacts for rx board, tx board and radio power, Mine was dirty and had no tx.

Also test the pre driver

I had a hand scanned they charged 2300 but blue cross has a contracted rate with any medical that takes their plans and they paid out 230 with no cost to me, so if you ever have to pay cash before the scan work a deal with them they will barter for price from the first quote.
