Compact LBQ-150 Guangzhou China Tuneable VHF Preselector for Ham Radio/2-Way

Description: This Guangzhou China model # LBQ-150 unit is a small, tuneable VHF Filter for use in VHF Ham Radio or Commercial 2-Way Radio Receivers or Transceivers. It appears to be a brand-new, unused unit. It came in a plastic bag with plastic covers on the input and output port connectors, which I believe are type SMA Female. Here's some of the LBQ-150 Specifications I found on line, from LA2YUA's site:- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Frequency Range (MHz) = 136~180 MHz Bandwidth (MHz) = 0.6-2.0 MHz Insertion Loss (dB) = 1.0-1.7 dB VSWR = ≤1.4 Isolation (dB) = ≥30 dB Maximum Input Power (W) = 30 W Normal Impedance (Ω) = 50 Ω Dimensions (mm) = 178×154×35 Weight (kg) = 0.75 kg Field Tuneable to desired frequency range.- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - The label says that this unit is currently tuned to a center frequency of 146.000 MHz. It came from a local Ham Radio Club's collection, that has a 2-Meter Repeater. Perhaps they originally ordered it to use with the Repeater, but never put it to use.There is some info on-line about retuning these similar units to a new pass frequency:"Most such preselectors are bandpass versions of mobile notch duplexers, with all resonators in series. you should be able to simply rough-tune the preselector on a spectrum analyzer for a peak response at the receive freqency. Then, install it in our receiver feedline and fine-tune it with a service monitor for best sensitivity at 12dB SINAD."I have a similar Celwave model 911-PB4-1-4 VHF Preselector for sale in a separate eBay sale, at the time of this listing.

Local pickup is also available. Shipping charges are based on other small electronic items of similar size and weight that I've recently shipped. Local pickup is available, but PayPal cannot be used for payment if you're picking up the item, since PayPal needs proof of shipment to be covered under their rules.Shipping is ONLY to a PayPal Confirmed Address. It is the responsibility of the BUYER to make sure the address listed on their account is correct. Please update your account address before buying, as I cannot send items to a different address than the one provided on your account. Any International sales must use eBay's International Shipping Program service, where I ship the units to their forwarding center, and eBay takes care of the necessary customs, etc. paperwork, and then they ship onward to the winning bidder. No Direct Overseas Sales! Because of the shipping arrangements that are done out-of-state, I am not able to combine shipment of multiple items. I ship items within five days of the end of the sale and receipt of payment. Please understand that once I've dropped off an item to be shipped, I have no further control of when it will actually arrive at your location. Occasionally, the shipping company routes the package through some far, out-of-the-way locations which can greatly delay the shipping time, compared to what eBay quotes for delivery times. Please see my other eBay listings for additional Amateur Radio and Electronic items. Thanks for looking!
