I highly recommend NOT using xtal. The few experiments I have performed with the 5351's, the TCXO became mandatory for stability. The 5351's I have, came populated with xtal. So, I got some TCXO's that will replace them.

I have been wrapped up in antennas and other things lately. I would like to contribute to this, but I don't have the bandwidth yet. I have an Agilent SA here, in addition to several others. But my 2 Aeroflex CSM's are down now. I have a couple of Rigol's, but I don't like them that much. They...

Rather than start a public debate, I'll message you.

I have used all of the variants. Repaired all of the variants. Tested all of the variants. The current Imax is trash. The old Imax is old. The Maco is not going to fall apart within 18 months, as an Imax will and won't have RF on the coax shield. There is better than a Maco out there, but if I...

Measure the signal level at the input of the counter.

You are still blabbering, about a DEALER, supporting a radio that they didn't make. When your Icom radio is not doing what you *think* it should, who do you contact for support? The dealer that sold you the radio that Icom made? Or do you contact Icom support? I know who I would be reaching out...

There is no magic here. The 5.6V Zener should have worked. I would use a 1 watt part, rather than the .5W the factory used.

Hello, I am looking for the Dyna-Com 3B pages from CB-46. I didn't find it posted. Thanks

Wanted Lafayette Comstat 25B Late Version Manual/Schematic/ Block Diagram/ Voltage chart/Alignment. There are two versions, early,uses 6AQ5 AF amp, 6AN8 RX OSC. The Late version uses, 6BQ5 AF amp and 6BL8 RX OSC. The SAMS I have, covers the early version radio, which, is not providing the info...

I don't remember what the Clipperton L, or SB-220 uses. If it that series switch, you have your answer.

I have a bunch of 5351's, only one is adafruit. I have put my DDS projects on the back burner, probably till winter. I probably have some fakes too. I need to look at them more closely.

In regard to re-ordering boards, I can't count how many engineers I know, that have been down that road, too many times, so don't feel bad about it. When you are all done, you need to measure phase noise. Have fun! SL

You could approximate, based on turns count, spacing and diameter, or Motorola application notes. Try posting a photo of the coil in question here as well.

Yes you are, for real.

800-850 measured with what? What mode? What is the level of the second and third harmonics?
