-====== 2023 Projects ====== 
-

- 
-==== May 2023 Update ==== 
- 
-=== Internet Connected Radio === 
-  
-  * I am going to avoid any radio modes/methods that **require** an internet connection. I feel more and more that amateur radio communication should be radio <-> radio only 
-  * The Internet is useful as an "accessory" to the actual communication (spotting for WSPR, PSKReporter etc.), but I feel increasingly that it shouldn't be a necessary part of the communication itself, which should rely on RF alone.  
-  * "Normal" Repeaters are okay - it's RF all the way: User <-> Repeater <-> User.  
-    * No DMR Hotspot 
-    * No Fusion/YSF Hotspot 
-    * No AllStar Link 
-    * No Echolink 
-    * No APRS i-Gates 
-      * I accept that my packets //may// reach the APRS-IS network via other i-Gates, but that doesn't mean I should run an i-Gate myself. 
-      * From [[http://www.aprs.org/]] 
-        * ''APRS is not a vehicle tracking system. It is a two-way tactical real-time digital communications system between all assets in a network sharing information about everything going on in the local area.'' 
-        * Nothing about APRS //requires// that the packets reach the whole world via i-Gates and the APRS-IS network 
- 
- 
-=== Transmitter Power === 
-  
-  * I am going to limit my TX power to 20W (all bands) for the rest of the year  (and possibly for ever?) 
-  * Some of my reasons for doing this include 
-    * No large, noisy PSU capable of the high current needed to power a 100W transceiver 
-    * 20W is still "reasonable" (not QRP) power 
-    * Easier to make homebrew equipment, antennas, ATUs etc. when only dealing with relatively low power 
-    * 20W radios only draw ~5A and can be powered from "accessory" socket in a vehicle (not ideal, but workable) 
-    * 20W will give an approximation of the power levels used in commercial/military manpacks 
-    * 20W will cause less RFI to equipment in the shack. 
-    * Lower power on the bands means less QRM, less reason for other people to feel the need to wind up their power etc. 
-    * It'll be instructive to be more mindful of propagation conditions, MUF, Critical Frequency etc. when choosing a band.  
-      * Be frequency agile, rather than brute-force a QSO with high power on a band that's really unsuitable. 
-    * I'm just perverse that way... 
- 
-== Steps to 20W == 
- 
-  * //Mothball// the IC-M710 and 60A PSU - which will liberate a significant space in the shack for new homebrew projects. 
-  * Use my homebrew 60m transceiver (plus commercial amp) at 20W for the bulk of my 60m digimode (Olivia, mainly) QSOs 
-  * Install the G90 in a more permanent location in the shack, for use on CW, SSB and digimodes. 
-    * I now admit that I'm not going to get //much// use of the G90 as a portable HF radio and it's a waste to leave it permanently in a Peli case in the van and never get any use from it. 
-  * Connect up the QCX+ 40m CW transceiver that I built but have never used on the air, and have some QRP CW QSOs 
-  * Change "Service" config of TM-D710 to make L -> 5W, M -> 10W and H -> 20W 
-  * Program any/all FM1100 for Power Level 4 (15W) on all channels  
- 
- 
-=== Plans for the year ahead === 
- 
-  * build 17m CW "phasing" RX 
-  * build 17m CW TX - QRP 5W 
-  * Work some CW using bug and straight key 
-  * Monitor 10m FM and try to have some QSOs - call CQ regularly 
-  * Install an FM1100 for 4m (& SIC Roads Low Band) in Shack - antenna?? 
-  * Work some more JS8Call 
-  * Work some more SSB
