Re: Time goes by

Hello Hubert,

Nice to hear that you like JUMA TX500. Unfortunately the "small" kits are discontinued. We are currently focusing on JUMA PA1000.
My plan is to share also the remaining PCB Gerber files of the "small" Juma kits soon, including TX136.

JUMA PA1000 with KX3 and PX3

Hello KX3 users, KX3 is a good companion with JUMA PA1000. If you have also a PX3 Panadapter you can get all the three tracking the frequency by connecting this way. http://www.jumaradio.com/juma-pa1000/PA1000-KX3-PX3.png JUMA PA1000 with KX3 and PX3 Note1.

Re: Juma PA1000

Hello Tilman, The switching to STBY state when changing a band is a default safety feature. That can be modified in the Service Pages so that PA1000 will stay in OPER state when changing a band and also when powering up. See more in the user manual found here http://www.jumaradio.com/juma-pa1000 73 ...

Re: PA1000 QSK

Hello Petr,

JUMA PA1000 is using a quiet and fast T/R relay with an operation time of abt 5ms. So it is almost instant QSK depending on your transceiver QSK settings.

Re: PA1000 and SunSDR2 Pro from Expert Electronics

Hello Slav, Sure, also JUMA PA100-D is compatible with SunSDR2. All you need is to provide PTT signal (TX ON) signal and use frequency detect in PA100-D. The PTT out in SunSDR2 is pin 13 (and GND pin 15) in the EXT CTRL connector. See those two wires shown in PA1000 manual but connect them to 3.5mm ...

Re: JUMA COM HUB and MacBook, KX2, PA1000

Ryan, We have not tested JUMA COM HUB with a MacBook. But it should work fine if you are able to connect MacBook directly to your KX3. All the the settings are the same as if connecting directly to the KX3 alone. You only need to set COM HUB for the same baud rate as MacBook/KX3. Read more here http...

Re: JUMA PA1000 with KAT-500

Hello all, Do not route JUMA PA1000 PTT signal via any tuner because it can cause hot switching in PA1000. The routing will spoil the PTT/RF timing coming from your transceiver. Typically the PTT signal (TX ON, SEND etc) comes abt 10ms before a transceiver is putting RF out and vice versa when you r...
