I recently picked up an early 60's Knight 6 Meter AM rig with the optional VFO. Cleveland area Hams have a retro 6meter AM net and it's been fun participating when they're on.

made a few quick-and-dirty monopoles for ~9.35 gHz to test some stuff in the lab. I'll see if they actually work this weekend, hopefully  wanted to try making discones but just don't have the time. I should be getting some that I purchased in the mail next week

The local Club finally got their weekly 10M net back on the air after a few years of old fart bickering. I Checked in with my Heathkit HW100 and all of the old guys went nuts over my old gear and begged me to come to the next meeting...  YOSPOS ham dudes, Should I go? These same people treated me like a punk kid when I tried to join the club back in 2008. MullardEL34 fucked around with this message at 10:34 on Mar 12, 2017 |

went to the national ham meet today with some pocket change picked up 20 6" SMA-male right angle to SMA-female bulkhead (with o-ring) cables and 14 motorola MHW720-A1 20W 400-440 MHz PA modules also i picked up some old Magnetic AB transmitter equipment another ham had promised me since he figured i could do something useful with it instead of it sitting in his garage taking up space didn't know exactly what it was until i got it, but turned out to be 2x100W 144-174 MHz PAs and another 8802A NMT450 transmitter which will do around 50W continuous ( already have two, one has previously been modded for 430 MHz operation) tested the PAs now and for 10W in they provide around 30-40W out after tuning the PA, rated input power is 20W and being class C amps they are very non-linear so that gain makes sense. might end up modding in a T/R relay in at least one so i can use them as standalone PAs with a mobile transceiver VHF PA  the PAs are quadrature coupled which means they will likely have a nearly perfect in/output impedance as well as work with antennas with high SWR without any significant issues NMT 450 transmitter

I have one of these: https://www.amazon.com/Kaito-KA200-Pocket-Radio-Black/dp/B00408K36Y It runs on AAAs and is super tiny, sound quality is decent through headphones. These look really cool though: https://www.amazon.com/Sony-ICFP26-Portable-Radio-Black/dp/B012F0DGYE/ https://www.amazon.com/Sony-ICF-F10-Portable-Battery-Transistor/dp/B0081IKTN6/

Olivil posted:not ham related but what's a good pocket sized AA powered fm radio these days? If you feel like making this into a fun evening project, take look at the Tecsun 2P3 Kit. Easy to build, cool retro case, and due to the huge ferrite bar and ceramic 455KHZ IF Filter, is actually a great little radio for doing AM DX. Apparently these are a sort of nostalgia item for Chinese radio Hobbyists. During the Cultural revolution the state supplied these cases to students to build their own homebrew transistor radios.    I've built three of them, one of which I modified to pick up 5-10MHZ shortwave. The mod involves adding turns to the ferrite bar and is easy to find online. https://www.amazon.com/Tecsun-2P3-Radio-Receiver-Kit/dp/B00LXK26QW https://www.youtube.com/watch?v=suDvdfjmNjk EDIT: Oops, I didn't see you wanted FM. Still, you should build one. It's fun. MullardEL34 fucked around with this message at 08:07 on Apr 19, 2017 |

So I received the radio and it's good! Impressive reception, it sounds surprisingly good even on the built in speaker and it feels well made. What do the pos radio thread think of the Tecsun PL-310et?

grab yourself an ARRL study guide (I got mine for free because I tagged along with my friend when we went to visit W1AW) and find when your local ham radio club is offering testing next. I'd consider getting both your technician and general at the same time - tech is harder for a lot of people than general so the added difficulty isn't that much, plus you can immediately start doing cool kid HF stuff like messing with large antennas, whereas with tech can be kind of limiting (hope you like talking to graybeards on your local repeaters about Obama).

ugh yeah. I want to use the magic box to talk to people other than local greybeards. perhaps far away greybeards okay actually I just like wasting money on blinkenlights and software with interfaces from windows 3.1

figured out the actual root cause of the stabilock calibration troubles the CCITT filter is implemented with opamps, and it turns out the output resistor from that filter chain wasn't properly soldered at all. i discovered that when i actually tried to use the filter as a bandpass to get more realistic distortion measurements and went from ~500mV signal to 2 mV signal with the filter in. soldered it properly, now it passes self-cal and self-test when it's both warm and cold. the worst part is the fault is even on the board the self test marked as bad, i could have caught that literally the day i got it if the self check had listed what test number had failed since the service manual has a fairly complete list of what each test number does

 http://earlyradiohistory.us/1924your.htm quote:How many well-meaning, fond American parents develop the home idea in the young boy? Are you not a bit to blame if your boy, when still in his 'teens, is seen too much in questionable company and in questionable resorts? Your boy is not naturally inclined to stay away from his home and his family. He is usually forced out, for want of something to keep his growing, inquisitive mind occupied; it's the something that he can't find at his home that forces him out. So out he goes. He drifts on, away from you,--the heartstrings loosen more and more, you--his parents--wonder and wonder and the boy becomes a stranger before you realize it. make your kid a basement dweller - a howto guide for parents
