Yes it did. I read it last night. I believe the same info is on the qrp labs website in the qsx area. James

Hi Richard, I copied the whole thing from one of the ARRL Handbooks. I'm sure I can find it again. I will have a look. I do still have the T-R switch and maybe even the coupling capacitor. That cap is

Didn't Hans QSX talk at FDIM and reprinted in QRPQ (October issue??) discuss a "relayless" TR switch? Jack, W8TEE

MFJ "Pin Diode Rig"....a model or part number?

There is this MFJ pin diode rig that I managed to pick up on ebay for $100. You might look around for another of those. They do take some tinkering I'm told. An even easier solution is to simply

Bill, do you have the schematic for the solid-state T/R switch, or even better, do you still have that switch? I am keenly interested in an all-electronic (no relays) T/R switch for QSK. Building one

Hi Vic Where did you get this information from please?? There does not seem to be any other posts indicating version? 4.3, which I have, is different.? My radio "works" but has very low audio

Try swapping the Black, and Brown wires on the Volume control. Black to the wiper, and Brown to the hot end. Sunil's instructions are incorrect. Philip G7JUR

you can use any waterfall (e.g. FLDGI, or even packet sound card software) to do the same.

zl1rd, Most likely the problem is the BFO adjustment.? We would need more information on which model and what equipment you would have for testing. I personally have found a free Audio Spectrum

Hi John Wonder if you have solved this problem?? I just finished my uBITX and experience the same issues you have....? receiver sensitivity very low etc.? Would you mind responding to zl1rd@...

It caught me out too, audio not good, AGC not good so decided to trace wiring. What a difference it makes!!!! G4GPF

Yes, the brown wire is actually v high and black is v medium.

I'm confused, are you talking about the connection from the volume jack on the front panel board supplied by inkits? The brown and black wires are reversed?

Yes, however the wire colour changed with the extra board. Apologies for miss spelling your name on my earlier post. Thanks again Philip.

Well thanks Phillip, wiring it up correctly made a big difference to the ALC operation.... Cheers Maurice

Could this be why my audio amp squeels when I turn the preset pot more than 1/16th up from off?

Oh, There's not much to do wrong, it's all up to the software!? But this program always seems to agree with the Elsie program by Tonne Software, so I think it's OK.? The values I am taking are from

Here is my posting from last year The wire up drawing has an error regarding the volume control connections. It shows the orange wire as being Vol_high. And the yellow wire as being Vol_mid, going to

Mark, That gives me confidence in how you are simulating these LPF's. Could be that the 80m LPF really does have a corner at 7mhz. Or could be that the boards are not being built exactly as described
