Hi Paul,
1) turn back on your SWR protection to prevent damage if something happens.
2) your power supplies and bias current are fine
3) it should be pulling somewhere near 1A on transmit
4) although most of your filter scans look like a pretty good shape, looking at the left-hand scale, you see they are not getting activated properly: the scale should be going from about 0dB down to about -35dB.? Confirmation that your transmit is not working properly.
5) your SWR scans are irregular, further confirmation that something is wrong with tx.
?
First, make sure you haven't put your QMX keyer in Practice mode (a P will be in the display after the frequency).? That would cause all of the above symptoms, because transmit is disabled in firmware, and stays disabled even while running diagnostics.
?
Otherwise, this type of failure almost always means that one of the following assembly issues is happening:
1) One of the ends of L502 is not connected well.? This is not uncommon, especially if your kit used the larger gauge wire.? It must be scraped well at the ends to remove the insulation, since it will not burn off.? Even the smaller gauge wire, which has insulation that will burn off with solder does not always contact well if not heated well enough - even if the solder connection looks perfect.? I recommend removing and scraping the ends of the wire, and replacing (if you had the larger gauge wire), or if you used the same gauge as for the toroids, heat it again with a soldering iron set to at least 370C, and heat each connection for at least 10 full seconds.
2) One of the connections of T501 is not good.? You said you already re-wound this.? It is not typically the windings that are the problem if you have no tx, it is the connections.? Especially the center-tap connection with the twisted wires.? Even if the soldering looks perfect, the insulation can prevent proper contact.
3) One or more of the connections of T507 is not good.? Only the one single-wire 'turn' that connects the signal to the output could prevent transmit, but I suspect that is not your problem because you are receiving well.? However, if any one of the other connections is bad, it will prevent the SWR and power readback in the diagnostics from working properly.
?
Since your current draw is so low on transmit, I suspect it is one of the first two issues above.? There are several other things that can cause transmit to fail, including improperly installed BS170 transistors, and failures in some of the pre-installed surface-mount components, but these are very rare problems.? By far the above mentioned things are the most common failures.? Even if you are sure you soldered well.
?
I hope this helps, and you find the problem quickly,
