[13:43] <ly2en> couldn't resist
[13:54] <dfgg_> nice, even just first little steps
[14:17] <ly2en> next logical step is to enable APRS on the dishwasher
[14:18] <ly2en> but hey, have more sondes over here
[14:18] <ly2en> maybe will try something else, the horus 4fsk

[18:25] <ly2en> so just noted that the metal string attached to the RS41 sonde is... ground?
[18:25] <ly2en> a counterpoise to the pcb antenna?
[18:43] <SA6BSS-Mike> only one wire out , tx antenna for all I know
[18:43] <SA6BSS-Mike> there is 2 counter pose to the pcb gps chip anntenna
[18:43] <SA6BSS-Mike> on the pcb
[18:47] <ly2en> but just checked, the antenna shorts with GND
[18:48] <ly2en> i would like to solder a SMA female socket there
[18:53] <SA6BSS-Mike> there is likely a inductor to gnd in the lp filter
[18:53] <SA6BSS-Mike> https://github.com/bazjo/RS41_Hardware
[18:54] <SA6BSS-Mike> yes, diagram shows gnd through 2 inductor
[18:54] <ly2en> a-ha, the L407 ?
[18:55] <SA6BSS-Mike> yes, 402 407
[18:55] <ly2en> roger that
[18:56] <ly2en> so I guess now it's time for this: https://www.aliexpress.com/item/32847381130.html
[18:56] <ly2en> :)
[18:56] <SA6BSS-Mike> you have got a freq for the beacon of the administration?
[18:57] <SA6BSS-Mike> theres usually a beacon coordinator
[18:59] <ly2en> not yet but working on it
[19:00] <ly2en> will probably be done sooner than stuff arrives from china
[19:00] <SA6BSS-Mike> cool
[19:01] <ly2en> not sure if I need a bandpass filter or a saw filter
[19:02] <ly2en> but maybe a good idea to put it before the PA
[19:03] <SA6BSS-Mike> the rf going into the pa is well filtered but you stil need a filter after the amp
[19:03] <SA6BSS-Mike> no saw filter in pa segment, a standrad 5 pole filter is good enough
[19:04] <ly2en> good enough to reject potential spurious emissions at low levels, before PA?
[19:04] <ly2en> ah you mean after the amp
[19:04] <ly2en> I don't want to drive the amp with something unrelated.
[19:04] <ly2en> like, with something out-of-band
[19:05] <ly2en> for example, before 2.4GHz PA on the qo100 satellite TX chain I use this: http://s.click.aliexpress.com/e/wSTsXc4

[19:25] <ly2en> and when you mentioned filter *after* the amp, you mean the 5 pole filter?
