FAQ:

Q: Can i use the PA100D amplifier with other QRP transceivers, other than the JUMA TRX-2 HF QRP TRx?

A: Yes, the amplifier can be used with other QRP radios, like the Yaesu FT-817/818, M0NKA mcHF SDR, Elecraft KX-3, Xiegu X5105, Elad FDM-DUO, IC-705, Juma TRX-2 etc. See a general interconnection spec. sheet HERE.

Q: How can i use the PA-100D with JUMA TRX-2 transceiver? Is there any interconnection cable available?

A: The interconnection cable [ROW-CA1] is available for purchase HERE. The PA-100D can be simple interconnected with JUMA TRX-2 via Digital Band Switch Mode. The F-sense mode will be selected in PA-100D amplifier. Cable will be connected to RS-232 jack (TRX-2) and to RS-232 jack (PA-100D). Interconnection cable ends are properly marked. Also, the RF drive cable is needed, between the TRX and the PA. A simple 50Ω, 0.5m-1m long, BNC-male to BNC-male cable is enough. Connection diagram available HERE.

Q: How can i use the PA-100D with FT-817/818 transceivers? Is there any interconnection cable available?

A: Yes, we built the interconnection cable [ROW-CA2] for FT817/818 radios. The interconnection cable is available for purchase HERE.  This cable allows the QRP transceiver in use to automatically select the desired band in the PA100D amplifier (Digital Band Switch Mode).The band selection in the transceiver is synchronised with the band selection in the PA100D. See the demo video HERE.

Q: How can i use the PA-100D with mcHF transceiver? Is there any interconnection cable available?

A: Yes, we built the interconnection cable [ROW-CA3] for the mcHF radio. The cable is available for purchase HERE. This cable allows the PA100D amplifier to receive a PTT T/R signal from the mcHF and the RF drive signal that will be detected by the Freq. Sense module (AUTO Band Det. with Freq. Sense Mode), in order to activate the TX mode (when OPER M mode is selected in PA100D). 

Q: How can i use the PA-100D with ICOM IC-705 transceiver? Is there any interconnection cable available?

A: The interconnection cable [ROW-CA5] is available for purchase HERE. The PA-100D can be simple interconnected with IC-705 via AUTO Band Det. with Freq. Sense Mode. The F-sense mode will be selected in PA-100D amplifier. Cable will be connected to SEND jack (IC-705) and to T/R (PA-100D). Interconnection cable ends are properly marked. Also, the RF drive cable is needed, between the TRX and the PA. A simple 50Ω, 0.5m-1m long, BNC-male to BNC-male cable is enough.

Q: How can i use the PA-100D with Elad FDM-DUO transceiver? Is there any interconnection cable available?

A: The interconnection cable [ROW-CA6] is available for purchase HERE. The PA-100D can be simple interconnected with ELAD FDM-Duo via AUTO Band Det. with Freq. Sense Mode. The F-sense mode will be selected in PA-100D amplifier. Cable will be connected to PTT-OUT (Elad) and to T/R (PA-100D). Interconnection cable ends are properly marked. Also, the RF drive cable is needed, between the TRX and the PA. A simple 50Ω, 0.5m-1m long, BNC-male to BNC-male cable is enough. See the demo video HERE.

Q: How can i use the PA-100D with Elecraft KX2/KX3 transceivers? Is there any interconnection cable available?

A: The interconnection cable [ROW-CA7] will be available for purchase HERE. The PA-100D can be simple interconnected with KX-2/3 radio via Digital Band Switch Mode. The F-sense mode will be selected in PA-100D amplifier. Cable will be connected to ACC2 jack (KX2/3) and to T/R (PA-100D). Interconnection cable ends are properly marked. Also, the RF drive cable is needed, between the TRX and the PA. A simple 50Ω, 0.5m-1m long, BNC-male to BNC-male cable is enough. 

Q: How can i use the PA-100D with Xiegu X5105 transceiver? Is there any interconnection cable available?

A: The interconnection cable [ROW-CA8] will be available for purchase HERE. The PA-100D can be simple interconnected with X-5105 radio via AUTO Band Det. with Freq. Sense Mode. The F-sense mode will be selected in PA-100D amplifier. Cable will be connected to ACC jack (X5105) and to T/R (PA-100D). Interconnection cable ends are properly marked. Also, the RF drive cable is needed, between the TRX and the PA. A simple 50Ω, 0.5m-1m long, BNC-male to BNC-male cable is enough.
