Kevin, Ramsey used to make an "audio multiplier" kit which would do what you want. I have one at home but am currently working away from home.
The other thing that will work is a Fluke 8060A DMM. That is what I use....it has a built in audio freq. counter. 73 John VE3AMZ ----- Original Message ----- From: Gmail - Kevin, Natalia, Stacey & Rochelle To: [email protected] Sent: Saturday, July 19, 2008 5:16 AM Subject: [Repeater-Builder] Getting a Freq Counter to Read Lower Hi All, I have a Optoelectronics Handi-Counter Model 2300. I brought it at Dayton in 1995. A great piece of equipment, and I use it alot. Still works fine, except I pulled the NICADs out a few year back, not holding there charge, and never got around to replacing them, works fine from 12v. However I had a need to read the freq of some CTCSS modules, but when I went to use my counter I found that it would only go to 1Mhz. I do not have another counter handy and I understand that I can build a small add-on board to get it to read down below the min reading of the counter. Is a multiplier the correct term? Any ideas on what I can do? If I have to get another counter so be it, but for the number of times I go below 1Mhz I would like to try other ideas first. Thanks Kevin, ZL1KFM.
