-The Antenna Switch was the last HPSDR component to be installed. It was originally installed next to the power supply on the outside enclosure wall with two standoffs. The first tests of the completed transceiver had switching noise throughout the HF spectrum. It was found to be radiated noise being picked up in the Antenna Switch due to its physical non-conducting contact with the main bundle of wires coming out of the power supply. Relocating the Antenna Switch into the corner at the end of the Atlas board solved the power supply noise problem, but there were too many undesirable narrow band signals with a dummy load on the rear antenna BNC connector vs placing a dummy load on the input BNC on Mercury. The Antenna Switch was installed in an enclosure (LMB #108) that is 2.25"X 5"X 2.25". The cost of the enclosure was $7.99USD plus local tax at Frys in Indianapolis. After installing the Antenna Switch in the corner next to the Atlas backplane as far away from any power wiring as possible, most of the added signals were eliminated. Note also the two clamp-on-toroids on the 25 pin ribbon cable. These toroids are required to block the conduction of unwanted RF into the switch. Also avoid ground loops to this antenna switch, as they will cause the noise floor to have a waveform indicating power supply noise. To eliminate the ground loop, only run a +12 volt line to the switch circuit board and leave off the ground wire.  See the new test results below ([[http://openhpsdr.org/wiki/index.php?title=A_complete_HPSDR_transceiver#Internally_generated_RX_signals| Internally generated RX signals]]).

-This program is required to get operating on digital modes. Follow the recommended settings given below and you should not have any problems.
-#Download fldigi-3.11.6-win from the Berlios fldigi archives. This is the only version of the program that is compatible with the other software programs we will be using.
-#Install at least two sets of com0com ports (COM5&15, & COM6&16). Go to [http://com0com.sourceforge.net/]to learn about and install com0com.
-#Install Virtual Audio Cable(VAC). Follow FlexRadio instructions: How to Setup Virtual Audio Cable (VAC) 4.0x with PowerSDR 1.x at [http://kc.flex-radio.com/KnowledgebaseArticle50230.aspx]
-#In PowerSDR setup>CAT Control set the CAT settings to COM5, 38400, none, 8, 1, then Enable CAT. Set the PTT control to COM6, check RTS and then Enable PTT. Set ID as: TS-480, no other ID settings will work.
-#In fldigi>Configure>Operator setup your data
-#In fldigi>Configure>Rig Control setup your data as follows: Check Use Hamlib, Rig: Kenwood TS-480 (new), Device: COM15, Baud rate: 38400, check RTS/CTS flow control, then initialize.
-#In fldigi>Configure>Rig Control>Hardware PTT Check: Use separate serial port PTT (yes, turn that little diamond dot to red), Device: COM16, Check: Use RTS, then Initialize. At this point you should be communicating between PowerSDR and fldigi. If not, shut down fldigi (remember to save the data) and restart. If it still does not work, recheck all settings and restart the computer, restart both programs, and then check for communications and TX/RX control.
-#In fldigi>Configure>Sound Card (Audio Devices) select: Port Audio (yes, that small red diamond again) and set Capture: Virtual Cable 2, and set Playback: Virtual Cable 1.
-#In PowerSDR>Setup>Audio>VAC set Driver: MME, Input:Virtual Cable 1, Output:Virtual Cable 2, Check: Auto Enable (Enable for Digital Modes, Disable for all others), Check:Stereo, Check:Allow PTT to override/bypass VAC for phone.
-#Use Modes DIGL and DIGU, TX Profile:Conventional, TX Gain so that ALC=0dB or less.
