Dear , I have looked at the schematics at that page. It's equal to that you created.

, Is this your project? http://transverters-store.com/psk.htm 73 de Kleibe PP2KR

Yuri Sorry. The language barrier sometimes get me confused.

, Stability of the frequency is a issue to deal in this mode. I'm thinking of a crystal heater....Maybe a crazy idea?

Yuri, I believe that for JT65 we need to generate a USB signal(I assume we are talking about 14 MHz). Do you transceiver works on LSB like the SmallWonder series? I think we can keep the winning team. Let's use your circuit as a model and lets see. Recently I have purchased an apartment at 23 floor so my shack it isn't assembled yet.

Well. UR4QBP did a good job redesigning a NWT7. He used a DC upconverter to reach 9V to feed a specific IC in that circuit. I will be happy with just 500mw!!! Doing it portable will be amazing. Have a look at http://ur4qbp.ucoz.ua/forum/8-141-1 And a DAC USB would be perfect. I need to test its circuit at http://www.pavouk.org/hw/usbcodecpcm2912/en_index.html Let's design some circuit in a CAD(my prefereble is Eagle since I have done a lot of work with it) and try to analyse the viability of it. About the boards: I have all except the Minima transceiver(that are all spoken for). We can exchange some boards if you like :liba:

Hi dear friend Bernat et all. Here in PY2 land has some dificulties to make PCB. If double sided is very,very expensive. So I need to make them in China. The price is about 30 to 40 times below if I try to make here. So I need to get in multiples of 10 in the chinese fab. The excedent boards goes to some folks at QRP-BR forum. I'm most interessed in JT65 and maybe a USB powered transceiver. Its just an ideia but I think you got it.

, I found you on youtube late night. I have seen your new pdf. Very nice and thank you for the new info. I have tried to make some transceiver but lots of daily obligations have prevented me to. I have make some boards from nice projects and you can have a look at https://pp2kr.wordpress.com/ I will send you a private email. 73 to all KLeibe PP2KR

Very nice design. Do you have a detailed BOM? 73 KLeibe PP2KR
