Hi Nick, for what band do you need a coupler and what is the legal limit ? Normally the resistor is the limiting factor or (if you speak of POWER) the SMA or N conector. 73, Rainer Am 23.06.2022 um 22

Hi Sam, if you do not sell the feed I might be interested. Can you send me pictures and what is the price? vy 73, Rainer Am 10.06.2022 um 13:31 schrieb SAM JEWELL via groups.io:

Hi Nick, I had this brick running @ 20W out 24/7 on DB0AJA until I shut down the beacon. Absolutly no problem !! Good luck es vy 73, Rainer Am 01.06.2022 um 04:36 schrieb Nicholas Shaxted:

Hi, I just checked my log and most stations were stronger on 3cm than on 6cm and signal getting smaller from band to band on 9cm, 13cm and 23cm. What I was told is that this is a result of the size of

Hi John, the best would be to reduce the output to abt. 20dBm (you can set it via the IF drive or use a 10dB attenuator) and get a RA181213G from Mitsubishi to drive the 23cm PA to 250W max. maintaini

Hi John, the 23cm PA can NOT be used with MKU 23 G4 as this transverter is for 13cm / 2.3GHz !!! You need a MKU 13 G3 !!! 73, Rainer Am 29.04.2022 um 13:16 schrieb lostbeach via groups.io:

The "transverter" is in the external box. The only conection between te box and the radio is an LAN cable as far as I can see. Am 17.04.2022 um 13:54 schrieb Stuart G1ZAR:

The ICL7660 is available for 10V and 12V input - the ICL7662 has a maximum of 20V input. Both are still available from Mouser. 73, Rainer Am 10.04.2022 um 12:57 schrieb Alan Melia via groups.io:

Hi Marc, the relay has a minimum isolation of 80dB @ 3GHz so it will be very usable at 3,4GHz. Also the Insertion Loss shpuld be no problem. Try it and you will be satisfied ! 73, Rainer Am 18.02.2021
