My third mcHF will no longer be QRP

-
A 120 watt mcHF variant is born. Even so, its size will be small compared to the much more expensive. Stay tuned


 Inside a Retex SOLBOX there is still room for a 120 Watt linear amplifier, four 7-pole low-pass Chebysehv filters, forced ventilation ... and even a 12-volt 20-amp switching power supply, but only if I can shield it for avoid interference from 40 kHz. In any case, a conventional 12-volt 2-amp source would facilitate QRP operation. A dial for CNC tool, instead of a simple button, I hope it gives a touch of distinction. 
Entertainment for my summer vacations.

      The covid-19 pandemic has slowed down my supply of components, but the project is well underway. I had not problems with unwanted couplings in the final amplifier, the partitioning through aluminum panels has made this possible. As soon as I can I will upload photos.

      Petr, OK1RP has left a new comment on your post "My third mcHF will no longer be QRP":

      Wow, I really like your project for 120W mcHF ! I home that you will successfully finish it. I am following you there and getting motivation for similar thing... :) Have a good luck mate! Petr

MiniPA-70 and MINIPA-100 step by step

-

The difference between transmitting with 5 or 12 watts of power in practice will not reach half a unit "s" in a remote receiver, however, that can be the difference in critical conditions to achieve a QSO. But the mcHF behaves much better emitting with its nominal power of 5 Watts, that's why a "help" in the form of linear amplifier is a better option when necessary. MINIPA-70 or MINIPA100 is a good  and unexpensive "help". My recommendation is first separate the supports of the transformers T1 and T2 (cut them from the printed circuit) and then solder the components of small size. Leave the fan and PTT connector for the end. These connectors prevent solder other nearby components and can easily melt due to excess heat. In this way the transformer T2 is built. The two small metal tubes are the half turn of the primary. Use a 100 Watt flat tipped soldering iron to build T1 and T2 and solde their brackets to the printed circuit board. Con...

Modification in mcHF V06 to make accessible the jumper P6 on UI-board

-
Image
The P6 jumper, located near the MCU, allows you to write the bootloader for the first time (in a new MCU) or also to replace the bootloader when necessary. The problem is that jumper P6 is located on the inside face of the UI board. It is highly recommended to "extend" the jumper towards the edge of the UI board. In this case, I stuck a waste of a female connector with glue and made the male jumper by joining two pins of a male connector. In this way you can rewrite the bootloader without having to disarm almost completely the transceiver.

mcHF V06 TX-RX antenna switching: Pin diodes vs Relay

-
Image
See also related post. mcHF V06 TX-RX relay antenna switching as implemented by Wolfram PY2BND This is the modification that I just made in my mcHF V06, inspired in df8oe RF-04/05/06-H-029   upgrade. In my case, I had to make the modification due to failure of pin diode D3. Clic here to see the df8oe modification Click here to see "The pin diode circuit designer' Handbook" The variant has been to connect a G6S-2 signal relay as a switch of the antenna signal, but taking care that capacitor C81 is earthed in TX mode. Else, in RX mode, the antenna is isolated from PA out. In this way, the shunt function of D4  pin diode is emulated. Protection by diodes 1N4148 -or similar- has always been discussed because the intermodulation effect that would cause an incoming strong signal exceeding 500 mV .Unlike df8oe, I used an NPN transistor to pilot the relay. Now switching transition between RX and TX is done the way that the RX band-pass is complet...
