The SODA POP was originally\ndesigned as a single band QRP CW transceiver on a 3.6\" square board. The mods\ndescribed below make it a multi-bander.\n\n**Warning**: I have not actually tried to use these files yet. They may have\nerrors. I shall in no event be liable for any claim, damages or other\nliability, whether in action of contract, tort or otherwise, arising from, out\nof or in connection with these files or their use.\n\nTwo versions are available: one with headers and either through-hole or SMT\ncomponents; one with SMT components and a DB9 connector. The DB9 one has an\noption for automatic band selection. Some modifications have to be made to the\nmain board for both modules.\n\nThe most recent version of these modules can be ordered from OSH Park from\nhttps://oshpark.com/profiles/PD7LOL.\n\n---\n\n- [Common mods](#common-mods)\n- [Through-hole / SMT module with headers](#through-hole--smt-module-with-headers)\n- [SMT module with DB9 connector](#smt-module-with-db9-connector)\n- [SMT module with DB9 connector and auto band selection](#smt-module-with-db9-connector-and-auto-band-selection)\n- [Horizontal format SMT module with DB9 connector and auto band selection](#horizontal-format-smt-module-with-db9-connector-and-auto-band-selection)\n- [Author \u0026amp; license](#author--license)\n\n---\n\n## Common mods\n\n### Main board\n- The following components are moved to the band module:\n\t- **TX**: C2, C3, C5 (and C6), C12, L7, L8\n\t- **RX**: L3, CT1, C31, CT2, L4\n\n\tTheir values can be taken from the manual under \"Band specific parts\". One\n\tpart, C31, is on the band module even though it has a fixed value (5p).\n\n### Software\n- The software has to be adapted as described in the manual under \"Manual band\n  selection\".\n\n## Through-hole / SMT module With headers\n- L3 has to be shorted (on the main board).\n- Add 2-pin female headers on the place of L7 and L8\n- Add 3-pin female headers on the place of CT1 and CT2 (middle pin should be\n  removed)\n\n![The PCB layout for \u003c160m](headers.png)\n\nIf you want to make a 160m module with through-hole components, the layout is\nslightly different to make room for the T50-2 toroids. Also, C31 is removed in\nthis case, and L4 is omitted (as in the manual). If building with SMT\ncomponents, you can use the same layout as for the other modules, short C31 and\nleave out L4.\n\n![The PCB layout for 160m](headers-160m.png)\n\nFor 80m, there is no separate layout. Simply leave L4 empty and short C31.\n\nFor 60m and 80m, the T37-2 should fit on the normal board.\n\nWhen plugged in, these band modules cover the ON/OFF switch on the main board.\nI would suggest either mounting the switch on the case or omitting it (and turn\nthe rig on and off by applying and disconnecting a battery or power jack).\n\n## SMT module with DB9 connector\n- Add a (male) connector to the main board using short coax cables. The parts\n  you should connect are L3, CT2, L7 and L8.\n\n![PCB layout for SMT/DB9, \u003c160m](db9smt-top.png)\n![PCB layout for SMT/DB9, \u003c160m](db9smt-bottom.png)\n\nThese files show T37-2 toroids, so they should work for all bands except 160m.\nThe T50-2 toroids for 160m will not fit any more, so they will extend beyond\nthe board boundaries.\n\nThe PCB is placed between the two rows of the DB9 connector.\n\n## SMT module with DB9 connector and auto band selection\nThis is a very nice mod to the above module, contributed by\n[David, VK3IL][vk3il]. It adds a [PCA9536][pca9536] that can be connected to\nthe I2C pins of the SODA POP controller to add automatic band selection. For\nthis, the firmware needs to be updated.\n\n![PCB layout for SMT/DB9/autoband, \u003c160m](db9smt-autoband-top.png)\n![PCB layout for SMT/DB9/autoband, \u003c160m](db9smt-autoband-bottom.png)\n\n## Horizontal format SMT module with DB9 connector and auto band selection\nThis version is designed to mount parallel and above the main board using a\nfemale DB9 connector on the module. It includes the auto-band selection feature\nand is sized to support T30 to T50 size toroids so can be used for 160-10m\nbands.\n\n![PCB layout for Horizontal SMT/DB9/autoband](db9-horizontal-autoband-R1-top.png)\n![PCB layout for Horizontal SMT/DB9/autoband](db9-horizontal-autoband-R1-bottom.png)\n\n## Author \u0026amp; License\nThese files were made by [Camil Staps][cs], PD7LOL and [David Giddy][vk3il],\nVK3IL.
