+===== Nachbau RF Board =====
+<bootnote> Das RF board befindet sich in Entwicklung, Alpha-Status. Die Daten des RF Boards können sich ändern.</bootnote>
+==== Test Adapter ====
+Einfache Realisierung von Testadaptern mit "Streifenleiter Platinen":
+  * Der kurze Adapter ist für den Labortisch. UI Board und RF Board liegen dann hintereinander. Über die zweite Buchsenleiste können Messungen am Header30 ausgeführt werden (geringere Kurzschlußgefahr). Die Beschriftung dient zur Orientierung der Pin-Belegung.
+  * Der lange Adapter ist für den Fall, daß das RF-Board aus dem Gehäuse herausgenommen werden muß (Länge 160mm)

-==== Tranverterausgang ====
-=== UHSDR Transverter Settings ===
-UHSDR unterstützt bereits die Transverter Offseteinstellung.\\
-* 10m-Band (oder 20m Band) wählen
-\\
-in Config-Menü XVTR Offs/Mult. auf ON\\
-eine Zeile tiefer in XVTR Offs die Frequenzdifferenz einstellen (in d. Regel die Quarzfrequenz)\\
-Ist zwar etwas mühsam, aber danach geht's (bei mir wiederholt mit DB0ETB getestet)
-=== RF Board Transverter Ausgänge ===
-I will add TE connectors to PCBs. The MMCX are much too big. You are free to choose the kind of adaptor you want.\\
-\\
-I recommend not to use the "standard BNC output" where signal already passed PA. My intention is a signal for transverting which is as clean as possible. The best point to pick it up is BEFORE it has passed PA stage (and AFTER it has passed RF preamplifier at RX).\\
-\\
-I will not follow the path "save each Cent I can save". In most cases "you got what you pay for". That means: "from nothing comes nothing". I know: that will make in complete an amount of ~50 Euros which can be saved. But that will result in much less flexibility, some lost of quality and complaining. I do not want to save that… And I do not want discussions like "CW signal quality is too low" or "transverter operation signal is bad" because of I saved some Cent.
-mit "TE-Connector" meinst du sicherlich die U.FL "Norm" ?
