I have been using the?Korad KD3005D for years now. It has all you need for a nice price (Euro 59) and with a real transformer in it (no switch mode power supply). 0-30V / 0-5A incl curent

I'm a bit of a newb. What bench power supply would you recommend for building kits like the QDX and QMX? I would prefer to buy a new product (vs used) and if possible like to keep the price to

Well Andy, I figured it out. Actually I accidentally stumbled onto a solution that causes the UL3S to do what I want it to do.? I've got 13 WPM CW for 1 minute, 30 seconds, then 20 seconds of

Jim, Jeffrey Moore has offered to help anyone get their qrp-labs kits fixed. He has the equipment to do it. Shoot him an email. jeffreymoore@... 73, Cliff, AE5ZA

Kieth, I am glad that you have the radio working. For the new kits with SMD components, I have bought two tools: 1 - A hot air rework station 2 - A desoldering tool. For the first, there are

Actually BS170 Ciss is 24pf. 24x3 = 72pf comparable to FDT86256’s 54 pf is not too off though QCX class E PA caps still might need some tweaking. 73 Barb WB2CBA

I might be interested if I can be of service to you. Meaning I will give it my best. These are too neat of a little radio to just junk. I can appreciate your frustration! 73KarlKI4ZUQ On Wed, Sep

Oh i see now. That makes sense. The BNC probably was shorted to the sma footprint on the PC board. I only wish I had worked on the BNC connector first. Perhaps T507 was ok after all.

You may have seen a post I did a few weeks ago regarding my QMX kit. After assembling it I discovered the dreaded short between Q103 and Q104. Power has NOT been applied. It is wired for 12 operation.

With just the jumper o C-C you should not have continuity from bnc center pin to ground. On the pcb there is a footprint for an sma connector. Make sure there is not too much solder and making

For those of you waiting to hear the end of my story --- I first cut the wires and removed T507. I then checked the BNC connector again and found the the center pin and body were still shorted. So i

Chuck, I posted this mod as an open source free mod with the thought that anyone interested can have their pcbs manufactured or get them as a group buy. I have no intention to sell these. First

Wayne, I did get a Linux PC running FLDIGI for FSQ. Got the Phaser retuned to 7105 ok. Antenna is good for 40M. I'm seeing some stuff in the 1500Hz range but not decoding yet. I'm sure I have to

Hi we should be able to use?only one FDT86256 in QCX. BS170 is 48 pF x3 = 144pF one FDT86256 is 55pF may be it might work better 73 muhsin TA1MHS

Hello All My U3S (with QLG2 GPS module) has been working well for several months, day in and day out, 24 hours a day. However, having had zero hits for the last 24 hours as opposed to the usual

Thanks, Garrett! I'm going to check that out.

Btw, I'm setup with an NVIS on 40 meters. Wayne

KD8CGH - I was on that abandoned voyage as well. Alas, I'm not wise to the ways of the 'tube' -- Dan Reynolds -- KB9JLO <><

I just received QMX kit so I took T30-6 and did a very quick test of the LPF. My order for the proper components did not arrive yet, so I just used some cheap 1608 ceramic chips. I only had those in

I will give the jumpers a try!
