Need 1 pf cap
Need one 1.0 pf ceramic disc capacitor low volts (<15 vdc) with .250"(6.4 mm) or less. Would accept two if you have a bunch but need just one.

Re: 270pf and 180pf capacitor swap on QMX
Yep- got the caps and made the replacement, and saw no significant difference. 20m was slightly higher and 30m slightly lower but that could just have been from moving the toroids around :) Thanks -

Re: 270pf and 180pf capacitor swap on QMX
You find any? I just woke up to this...so sorry! I am not getting any notifications on this page!? Need to fix that...
Let me know what you need, please!

270pf and 180pf capacitor swap on QMX
I decided to make the swap on my early version QMX which had these caps reversed in position in the instructions. The easiest and safest way is to clip the leads and replace them. Anybody have 270pf

Re: Anybody have SMD 49.9 resistor and/or BNC connector?
This stuff plus the braid. Dab some of the flux from the tube, apply some of this low melt solder on the pads, swish it clean with the braid. Then put a little dome of the low melt on each pad. Hold

Re: Anybody have SMD 49.9 resistor and/or BNC connector?
I have regular paste flux, more like waxy ointment really and copper de-soldering braid. I have removed a few SMD resistors before using a doubled over two pronged wire on a soldering iron. The part

Wow! I been trying to send you that link through out the day! Good! Good for you!
Do you have low temp solder used for removing SMD components and the special flux? I will hush if you are experienced

Re: Anybody have SMD 49.9 resistor and/or BNC connector?
I am now (or will be in 2 weeks) the proud owner of 100 49.9 Ohm SMD resistors for the QMX radio. These are from Amazon, size 402

Re: Anybody have SMD 49.9 resistor and/or BNC connector?
The size of the R522 49.9 Ohm SMD resistor on my QMX looks to be about 2mm long. Here is a snapshot of my board. It was only a small corner sheared off (don't ask) so it might still be good enough...

Check regular email I sent you this morning but someone on here will have a resistor, I will bet! The BNC may be had from Hans to make sure it fits.

I managed to damage R522 on the lower right corner of my QMX while removing the right angle BNC connector. The resistor is labelled 68X or maybe X89 and is 49.9 Ohms. The BNC broke its center pin

Re: Spare 47V 1W Zeners
I meant to say "1N4148s or 1N4756As."
Arrrgh.
I might have to throw some 6A10s out there to really mix things up.

Re: Spare 47V 1W Zeners
Be sure to specify 1N4148s or 1N4148s.
That a typo or do I need to learn something? Har, har!

Spare 47V 1W Zeners
Fresh from China, still on the tape, 47V 1W Zeners, ?.
These aren't from my free pile like the 1N4148s, so I'll have to limit all takers to 5 each.
