As Harold mentions, it can be done with TN0110s, I've done so in several QDXs. But I would NOT do this in a QMX. -Nate N8BTR

I'd like to acquire a 10 - 50 watt linear power amp to use with a 50 MHz. beacon transmitter. Input must be in the 10-18dBm range. Kit or assembled or "needs repair" is

No it would just be difficult to make it work

Why not just get a transverter? There was a ham in Ukraine that had a store before the war started. No one else seems to be interested in picking up that mantle (that I’m aware of).

Did not investigate the component TN0110 further, but may provide opportunity in combination with an "U" shaped heatsink instead of a washer when installed in a neat way. Harold PE1RJP - Happy QMX+

I’m interested in one full kit, if another group buy happens. Thank you for what you do! tom KE5CW

Rick, the 0603 size (first checked item) would be the easiest to work with. If you have a small leaded 150 ohms resistor, you might be able to solder it in that spot if clearances work out too. Good

Hi all, I was trouble shooting a problem with my QCX mini for 20m Rev. 3 board T1.09a When I would push down on the tune rate knob or even? touch the knob to adjust the volume the volume would drop

Stan, Guess I won the dummy award of the year on the 1st day. The QMX+ was in Digital mode. Set it to CW and all is well! Tnx, Tom KT4XN ________________________________ Sent: Wednesday, January

Joel, thank you very much for your wishes. I don't understand the thing with the cathodes. To the anode is ok but to the cathode the same time? All the five points are related to the LPF section. If

Many thanks Stan, I will have a carefull check. 73 hanz

First checks: 1) do you have the QMX+ in CW mode?? It will not react to the key in Digi mode 2) does a 'P' or an 'S' appear on the display after the frequency?? If so, you are in Practice mode or

Received a new factory assembled QMX+. Testing with a 9 volt battery. This is a 12 volt QMX+. The receive is excellent. However, there is no transmit on any band. Tested into a dummy load with a

I would also like to be included in a group buy if it happens for 1 unit.? Thanks for your work on this gentlemen! Martin, K0MJ

Nico, the final price per unit would be determined by the number of participants, and the related quantity discounts we can get. But for a ballpark estimate, for the first buy with 35 circuit card

All these pins should be supplied with 2.5V from the R401/R402 potential divider through T401.? There could be several open circuits around T401.

The power pins of the QMX+ USB connector are not connected to anything in the QMX+ design, so they should not be pulling any power at all from your Mac mini, so you may have a short somewhere in your

Nuts, yes! Welcome to my life. Yeah like my QCX-mini test fixture: https://youtu.be/xb_ZmPx7Py4?si=DVGts9JtbolOTpCU It took me 3 R&D-Weeks to build that. I shudder to think how many actual elapsed
