The speaker is a nominal 8 Ohms. This doesn't explain why the IC-705 and IC-7300 can drive it with no issue at lower audio power output rating. -- 73, Norm/KC1BMD

Impedance of the speaker

I was using a small (non-powered) bookshelf speaker with an IC-705 and IC-7300. I'm not sure about the IC-705 but the IC-7300 is spec'd at 2.5W audio output. Either rig could drive the speaker with no

I use a pi for my shack, mobile and and portable all running KM4ACK build a pi.? I don't use the digi rig so I can't help you there.? Maybe ask around on KM4ACK group.? Are you using the pi 3 or 4?

I went looking for this specific topic and got lost in the wealth of topics on the site. Can you provide link to the resource for this battery project? -- Grace & peace, Tim AF6TF

those are great little speakers... i use one w/my wb7fhc m2 decoder:

Hi Axel, Congratulations, very well engineered! I also like the two 24Wh Eremit LiFePO4 batteries that I use myself, which are rock solid, are less problematic with heat than Li-Ion and have a flat

I was waiting for the battery pack to come... While doing this I decided to build my own one mounted directly to the TX500. It is based on two 2 Ah LiFePo4 batteries. And the main advantage of this

I get it, i have thought about going that way; but, the portablity and power of the pi fits my goals. Once i get the programs running fine, i will just clone it into a few more sd cards to just do a

I realize this doesn't solve your problem, but I have gone thru three different Raspberry Pi's (Zero W, 3b, and 4) in an attempt build a robust, modular, field station and everything was an uphill

I would really appreciate any assistance with my problem of gerting js8 up and running with my portable rig. So, thank you all in advance! Tools: Pc: Raspberry pi Codec: Digirig 1.6(?) Bought with

Not specifically for the TX-500, more just off-grid power backup, due to the rolling power outages in California (PSPS, public safety power shutdown)

I very much look forward to seeing a pack from Lab599 or DIY599. Today I use 3S1P 5Ah Telsa Gen 3 21700 pack I build after I snagged 50 of the cells from a company out in CA over 2 years ago. I can

very nice, chris... was the battery pack for the tx-500? i enjoy building simple accessories, such as this (off-topic here) $6 touch key, but would love to have a homebrew form-fitted battery pack:

According to Roman (Lab599) they are in final stages of development and testing a prototype in preparation for production. There was no timetable provided. It will be interesting to see which battery

I prefer LiFePO4 for safety reasons, supposedly what Oliver is using. -- 73, Norm/KC1BMD

Hello group. I use this battery for my TX-500: https://www.windcamp-gear.com/productinfo/372615.html It's been 10:30 I use it for testing and the voltage is still 10.7V. 73 Jo - F5NFB

I’m considering a flat pouch lifepo4 battery pack just for fun but that’s a month or so away Nick Smith KJ7NWK

Nice project and sounds like you had fun. For me, building a battery pack is far down on the list of projects to do. -- 73, Norm/KC1BMD
