 Another goal is current consumption of less than 0,3- 0,4 A but this seems to be difficult with the existing units ([[OZY|Ozy]], [[MERCURY|Mercury]] and PC/ controller). If we can manage to get all into this box and working with suitable software, we can modify the hardware and use less power hungry components for a 2.nd generation transceiver.
-Using latched relays for filter switching will save power. This will require modified software but should not be difficult. The interface to [[[HERMES|Hermes]] will be I2C.

 The LP Filters will be based on Alex but with only one Antenna connector. The toroids may be smaller (T38 instead of T50). Also the capacitors can have lower voltage ratings. An Antenna Tuner can also sit in on the same board. (LDG makes good tuners so it may be possible to use one from them)

+Today I posted a new version of the schematic and PCB layout of '''Apollo''' and ATU ([[Apollo - Development Discussion]]).
 I have included an ATU on the 100X160 Eurocard. For this, we use an ATMEL CPU, AT90USB1286-16AU. The ATU has 8 Toroid wound coils and 8 Mica capacitors controlled by 17 latched relays for low current consumption. The CPU can be programmed via JTAG, USB and also I2C from Hermes. Software for the ATU will be created by LA7DJA, Espen.

 I am in the final stage of the PCB layout. The PCB had to be 4-layer. The complexity and compact size prohibited the use of only 2-layers. The stability of the circuits are highly improved with one layer with a continuous Groundplane.
