I see you have the instructions already, Jim. But for anyone else, Link supplied !!

Just noticed this. Maybe it will help you. Lightning Antenna assembly instructions (L6): http://www.radiomanual.info/schemi/ACC_antenna/Lightning_antennas_L6_user.pdf

Jim, antennas can be a pain in the @$$ for sure. But honestly, this is how you learn, OM! You will always have a different SWR readings in the shack if you do not isolate the antenna from the feedline. Remembering you are testing, a choke made from RG-58 or RG-213 would help you. (Just as...

Hi Jim, you've go a good team on this forum! Interesting topic. After 40 years in radio, I'm still learning too! To expand on one topic, use of chokes. I always use a 1:1 baluns (or choke) at the feed point to my antennas. In fact, I also use current baluns on my radio, to reduce noise. They...

Northern California, 1 hr north of Sacramento Power to the antenna is 69 Watts (miscalculation in Technical Info)

Here is a picture of the FT8 Contacts for the 10M HAM band. All locations are in reach of this repeater. This of the possibilities!!

Something new for the summer skip/DX season: A new simplex repeater is "up-and-running" in California on 27.935 MHz To use simplex repeater, you simply transmit a message (talk)! The repeater will record & then resend what you sent (said). There is a maximum of 30 seconds of message time...

finshin' pole with a strange reel ???

I have used another "Ebay" signal gen from CN in the past, similar to this one. The only problem I found with it is it will not modulate a signal on CH1 (AM or FM) with the generator on Ch2 or an external audio input. For a function generator or signal generator it works fine for $100

Thanks for the heads up. Looks nice, but......

Came across a schematic of the SSM2166 with variable low (bass) an high (treble) gain controls + an input attenuator (pot). Credit goes to WA1QIX

Hi Guys, I thought about more this thread and considered that most operators would in fact consider "sensitivity" as the key to the "best receiver" not necessary sound quality/ lowest THD. Having said this, I have an old President radio which would only receive -110 dBm signal with 12 dB of...

Has anyone performed any SINAD testing on any modern radios? I have the Radiodity QT-80. I may test this one. This was a pretty shocking test outcome from a modern (last 10 years) radio (SINAD vs price!): 37.5 dB!

Nice one, cable guy! Crazy the size I'm thinking of the same concept of the 7805 and dual-gang pot adjusting. My boards arrive at the end of the week. Post what find once you get it going. It should be interesting to mess with. Thanks, Michael

Yep, I bought a few myself, Cable Guy As Shade Tree noted, & M0NTV also found, R1 and R2 were misloaded on the boards he received: no compression was taking place as received off ebay! :-OO So verify the values of R1 and R2: R1(gate): 15K ohms for 2:1 of compression (or use a pot) R2(comp)...

Guys, I do not see any postings for Audio Compressors using AD SSM2167. There are plenty of posts for the CB City International speech processor, which are unavailable. I used one back in the day... Here we are 2025.... Just FYI, Assembled compressor boards, based on the Analog Devices...

Hello Group, I have a President Madison from Europe with a 220V/50Hz Intermatic motor on the analogue clock. I am looking for a 120V/60Hz Intermatic motor to use in the USA. Any available for trade / buy? Thanks

Hi All, I have a Anytone Apollo II (H) 10m rig. I am looking for the programming s/w, which supports this model (APOLLO_2H). I'm looking to programe the CTCSS tones for different repeaters on 10. Anyone have it that could post or send a link, please? FYI, The Stryker 94 and standard Apollo...
