Have any of you lovely hams found a handheld transceiver with a dial or knob for going through presets / scrolling through the frequencies?

My 25-year-old Radio Shack HTX-202 has a rotary encoder for tuning.

yeah i have about 13 of them. what i think you're running into is that a lot of DMR radios are basically adapted from commercial/cop radios, which rarely had general purpose encoders for tuning or switching freqs. 99% of actual purpose-built ham rigs have them. (my ic-w32a has two!) my md380 has a 16 position rotary switch to pick talkgroups but it's not continuously spinning, there's a far left and right position. This is actually nice if you're trying to operate it blind - i know exactly where the goon talkgroup is by feel <waggles eyebrows>

PSA: .radio domains are 25 euros a year if you're registering your callsign. There are a few other ways to get the ~90% discount, but this is the one I care about You need to go through register.radio to get the discount - all the other registrars i checked like Gandi only sell for the full-price 200-something euros/year. register.radio makes you fill in your contact info for the various WHOIS contacts, but don't expose that information after registering - I emailed to ask because I didn't see a whois privacy thing during checkout.

ill post it here too. stupid afternoon project. APRS mini box.  pi zero W audioinjector pi hat (VERY nice, strong recommend. Don't gently caress around with USB sound dongles) ancient yaesu ft-270RH on 5 watts PTT on GPIO pin 26 via a 2n2222a and resistor 9-20V to 5V buck board for power (just added a power lead off the radio feed) poo poo owns and it works perfectly if i add a GPS hat, a battery and maybe an LCD touchscreen to this i could have an ammo can tracker/messagebox

goddammit my hotspot hat arrived and i have to remove a tiny rear end SMD resistor for it to work on a pi4. i tried it on my old pi1 and the wifi is hosed up if i use the pistar image. haven't tried connected to ethernet yet, but that's not really a long term solution for me unfortunately i'm very disappointed.

well, i'm gonna try it, but while i've done SMD before it's way easier in my experience to solder than ti unsolder this kinda stuff. maybe i can find some braid that'll help though. i'll give it a shot but it'll be a miracle if it works afterwards any idea on if i should bridge or leave the short? i imagine the answer is bridge, but the broken-english instructions just said remove...

i am suspecting its putting a voltage where it shouldnt. remove, don't bridge. if you want to Be Bold just grab the finest tweezers you can find and rip it off. dont be too hung up about needing to desolder clean. you'd never be able to resolder it back on anyways. just dont gently caress up any adjoining traces or through-holes

Holy poo poo, that worked. I just pulled the little fucker off and it booted! Thanks a million, dude. Today has been Rough (unrelated to the hotspot being broken-ish) and getting a little dumb ham radio win like that really feels good right about now.

lol well it looks like it doesn't actually work - once i found a modem type that could successfully reset, MMDVM_host still can't read the firmware and such from it still feel good that i got it to boot tho. maybe i'll give it a shot on the old rpi1 tomorrow

while I'm studying for my license I'd like to at least get used to pulling poo poo out of the aether and listening to it, and it looks like RTL-SDR dongles are *deeply* on sale on amazon.ca right now but not the full antenna kits. is there a recommended type of antenna or anything for those or is any ol' antenna with an SMA connector on it fine?

HF update: it occurs to me that if i get permanent WFH, there's a reasonable chance that i'll move into a place where i can put up an antenna, even if it's stealth mode on top of the roof or something. and if that's the case, a QRP radio would still be cool but i'd probably go for a 7300 first i tell myself this to keep myself from blowing the bonuses i got today (and then some) on a 705

unless you are like seriously a hike/camp addict get the 7300. besides you can run it off a battery if you go car camping or w/e 100 (actually mine pushes like 135, 140 depending on band) watts makes a huge difference in enjoyment

like, i CAN drive but i hate it because i'm colorblind and have no depth perception. driving safely is a much more difficult and focused thing for me cause it is way harder for me to tell the difference between "traffic slowed a little" and "traffic stopped, you better slam on the breaks right now". basically if there's any traffic at all i'm white knuckling it. i miss the days when my eyes were just as hosed but i didn't realize how much it effected me

gotcha. yeah lol uh the 7300/9700/705 are quite possibly the _worst_ radios to use actually mobile. just say no to touchscreens in a moving vehicle. anyways yeah get the 7300 first. i love the 705 but its limiting if you arent an experienced op with a quite good setup

i need help from you radio heads! i was talking to a friend about getting into SDR, and she mentioned having one of these Soma Ether devices https://somasynths.com/ether/ it seems cool to walk around and listen to RF emissions, but i can't shake the idea that this is just a normal FM radio thats missing a tuner. what am i missing? then there's this VLF receiver http://www.auroralchorus.com/wr3gde.htm which seems like the same kind of thing, but specifically set up to receive low frequencies (and no demodulator). seems like it would be more fun to monitor natural phenomena with this, vs overlapping FM broadcasts with the Soma. my question: what do radio heads think of these?
